Last window pane list!
Last window panes for Biology:
1.Excrete- to rid yourself of wastes (sweat, urine, feces, tears)
2.Optimum/optimal- The best possible condition or situation- the optimum temperature of our classroom is???? The optimal speed of your computer?
3.Immune system- system in an organism that protects it against disease by identifying and killing pathogens(anything that can make you sick) and tumor cells.
4.B-Cells- type of white blood cell (called a b-lymphocyte) that produce antibodies. B cells develop from stem cells in the bone marrow.
5.Helper T-Cells- Helper T cells do not directly kill infected cells, they help activate killer T cells and macrophages to attack infected cells, or they stimulate B cells to secrete antibodies.
6.Killer T-cells-Attack and lyse (split open) specific cells that contain antigens.
7.Vaccine- substance that improves your immunity to a particular disease. It is made from weakened or killed forms of a virus/ pathogen or its toxins. It jump starts your immune system so that if you are exposed to the real virus (small pox, avian flu,swine flu,polio, etc) your immune system can more easily recognize and destroy the virus so that you don’t get ill or so your illness is brief and you suffer very little.
8.Virus-A microorganism smaller than a bacteria, it can’t grow or reproduce apart from a living cell. A virus invades your cells and uses the chemical machinery of your cells to keep itself alive and to replicate. Viruses will make many clones of itself or mutate when being copied. Mutations lead to the virus being slightly different in each person.
9. Antigens-any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment such as chemicals, bacteria, viruses, or pollen.
10.Antibodies-a specialized immune protein, produced because of the introduction of an antigen into the body. Antibodies are specific to the antigen it is fighting and they remain in your body even after the antigen has been defeated- ready to fight another day!!
11.Bacteria- prokaryotic organisms that lack a nucleus (but have DNA), lack membrane bound organelles, but have a cell wall and ribosomes. We use them to make human insulin by transplanting our DNA into their DNA (called a plasmid). Some bacteria are harmful so we use antibiotics to destroy them- antibiotics work to destroy their cell wall and since we don’t have cell walls – we’re OK J!tetanus, pneumonia, syphilis, and tuberculosis are a few illnesses caused by bacteria. (don’t forget MRSA and Strep.) http://www.livescience.com/bacteria/
12.Malaria is a mosquito-borne disease caused by a parasite ( a protist called Plasmodium). People with malaria often experience fever, chills, and flu-like symptoms. They may develop severe complications and die. In 2008, an estimated 190 - 311 million cases of malaria occurred and between 708,000 - 1,003,000 people died, most of them young children. *** people with sickle cell anemia seem to have resistance to malaria, making sickle cell a positive adaptation in this situation!!!

13.Cholera-is an infection of the small intestine caused by the bacterium Vibrio cholerae. The main symptoms are diarrhea and vomiting. Transmission is through consuming contaminated drinking water or food.
http://www.npr.org/2010/12/10/131950133/doctors-urge-cholera-vaccine-for-haiti-neighbors
14.PKU-Phenylketonuria (PKU) is a genetic disorder that is characterized by an inability of the body to utilize the essential amino acid, phenylalanine. Babies are checked at birth for PKU, if positive, babies are put on a special diet and do not suffer any problems. If it is not caught, the infant will suffer a wide variety of problems including seizures and mental retardation
15.HIV-Human immunodeficiency virus (HIV) is a virus that causes acquired immunodeficiency syndrome (AIDS) condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections. It is transferred through bodily fluids. (Helper T-Cells and macrophages are the most affected cells).
16.Urinary system-The urinary system or excretory system is the system that produces, stores, and eliminates urine. In humans it includes two kidneys, two ureters, the bladder, the urethra, and two sphincter muscles. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other compounds. Remaining fluid (URINE) contains high concentrations of urea and other substances, including toxins.
17.Circulatory system-The circulatory system is an organ system that passes nutrients,gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis.
18.Essential nutrients-is a nutrient required for normal body functioning that either cannot be synthesized by the body at all, or cannot be synthesized in amounts adequate for good health. It must be obtained through your diet. Eight amino acids are generally regarded as essential for humans: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, and lysine.
19.Environmental toxins- substances in our environment that can make us sick- lead (neurological disorders), mercury ( neurological disorders), pesticides, herbicides, biocides ( cancer causing agents)
1.Excrete- to rid yourself of wastes (sweat, urine, feces, tears)
2.Optimum/optimal- The best possible condition or situation- the optimum temperature of our classroom is???? The optimal speed of your computer?

DNA song
DNA/RNA song
I hope you enjoy this, my son helped me write it!The Replication, transcription and translation song – to "The Adam’s Family" theme song
There’s adenine and thymine
Cytosine and guanine
A phosphate and a sugar
And that makes DNA
DNA(clap, clap) DNA( clap, clap) DNA,DNA, DNA (clap, clap)
When thymine goes a missin’
Uracil is there to listen
It sends a little message
Because it’s RNA
RNA (clap, clap) RNA (clap, clap) RNA, RNA, RNA (clap, clap)
Transcription’s then completed
the code gets translated
acids are created
Then proteins are made!
Hip hip hooray! (clap, clap) Hip hip hooray! (clap, clap)
proteins are made, proteins are made, proteins are made!!!!! (clap, clap)
THE STRUCTURE OF AN ACTUAL DNA STRAND IS SIMPLE AND BASIC, IT’S THE PATTERN OF THE CODE AND THE LENGTH OF THE CHAIN THAT MAKE DNA VALUABLE AND YOU UNIQUE!!!!
REMEMBER YOUR ORGANIC COMPOUNDS? THE SMALLEST FUNCTIONAL UNIT OF A NUCLEIC ACID IS A PHOSPHATE, A SUGAR AND A NITROGEN BASE EITHER ADENINE, THYMINE, CYTOSINE, GUANINE (URACIL REPLACES THYMINE IF IT IS A STRAND OF RNA INSTEAD OF DNA).

Prelude to genetics
Deep thoughts by Thomas Hardy:
Heredity
I am the family face;
Flesh perishes, I live on,
Projecting trait and trace
Through time to times anon,
And leaping from place to place
Over oblivion.
The years-heired feature that can
In curve and voice and eye
Despise the human span Of durance -- that is I;
The eternal thing in man, That heeds no call to die

Next word list: #6 (20 terms)
WORD LIST- for DNA and mitosis1. Complementary base pairs- The nucleotides that fit together to form the DNA double helix, adenine with thymine and cytosine with guanine . Here is a visual, if the original strand of DNA has the following bases: A T C G A T T C G A T (ORIGINAL OR TEMPLATE)Then the complimentary bases would be: T A G C T A A G C T A (COMPLIMENT TO THE ORIGINAL) 2. Replication- the process of copying the original strand of DNA to form a new, IDENTICAL, strand of DNA so that when the cell divides the daughter cells have the same exact genetic information as the parent cell.3. Mutation- any change in someone’s strand of DNA, it could be a few letters (bases) or just one base.4. Protein synthesis- using a cells DNA to code for and then make a specific protein needed by the cell, three types of RNA are needed to do this.5. Trait- a physical characteristic or feature of a person (ex; brown hair, tall, diabetic, blue eyes)6. Genes- the segments of a person’s DNA that code for a certain trait. 7. Transcription- when mRNA copies a segment of DNA in order to take the message out of the nucleus and to a ribosome. It must be written in the RNA’s language which uses Uracil in place of thymine for a nitrogen base. The uracil still pairs up with Adenine.8. mRNA- messenger RNA is the RNA responsible for sneaking into the nucleus of a cell and copying off a certain piece of DNA and then carrying that piece of the code out to a ribosome. 9. Codon- three letters of a mRNA strand that determine which amino acid is to be made by a ribosome.10. Translation- when the code made by the mRNA gets turned into an amino acid in a ribosome.11. rRNA- is ribosomal RNA, it’s what makes up the ribosome and turns a codon into an amino acid.12. tRNA- is the type of RNA that puts all of the amino acids in the correct order to form the proper protein. It has a complimentary RNA code for the newly produced amino acid to hook on to.13. Polypeptide bond- it’s what connects one amino acid to another to make a complete protein.14. Non-disjunction- When the chromosomes are not pulled apart evenly during anaphase of meiosis. This is what leads to Down’s syndrome (aka: trisomy 21 which means three of the 21st chromosome).15. Chromosome- a condensed segment of DNA, humans have 46 chromosomes in every cell in their body,(except egg and sperm)16. Chromatid- half of a duplicated chromosome- the whole X represents two sister chromatids!17. Mitosis- the process of forming two new, genetically identical cells (skin, liver, hair, muscle, blood, etc. all of these cells are referred to as being 2N= the whole chromosome number, one set from Mom and one set from Dad)18. Meiosis – the process of forming 4 new, GENETICALLY DIFFERENT cells with half the genetic material of the original cell. These cells only have 23 chromosomes (they are called 1N)19. Zygote- forms when the egg and the sperm unite and make the first cell of a new organism.20. Allele- a choice for a trait, you have two alleles for every trait in your body, one from mom and one from dad.

2.Mitochondrion (singular) - responsible for breaking down sugar (glucose from plants) into a more usable form (ATP) for our cells. Found in animal cells and plant cells. Cells that do more work have more mitochondria in their cells (muscle cells and sperm cells have the most!).
3.Centrioles- organelles found only in animal cells that are only active during cell division (mitosis) where their job is to make sure that duplicated DNA strands get pulled apart evenly.
4.Ribosomes- found in plant and animal cells, they are responsible for building proteins and enzymes in a cell by using instructions they receive from the DNA via an RNA strand.
5.Nucleus- the control center for the cell, it contains the DNA instructions used to make every part of your body, your DNA NEVER,NEVER, NEVER leaves the nucleus!!
6.Cell wall- found only in plants, it provides structure and support to plant cells.
7.Cell or plasma membrane- found in plant and animal cells, it controls the movement of all substances in and out of the cell. SUPER IMPORTANT!
8.Cytoplasm- gel-like substance that all of the organelles are suspended in, it provides a medium for nutrient exchange as well as a cushion for the organelles.
9.Bioenergetic reactions- Chemical reactions in a cell that involve the creation of energy from sunlight or the break down of sugar for usable forms of energy: ex.- aerobic respiration (breathing), anaerobic respiration (fermentation), and photosynthesis.
10.Activation energy- the least amount of energy required to start any chemical reaction. (You have to start cellular respiration with 2 pieces of ATP in order to carry out the reaction and obtain 36 pieces of ATP)

transport videos
transport across a cell membrane interactive
Go here to see how cell transport works and get some visuals for your window pane terms!http://www.wiley.com/legacy/college/boyer/0470003790/animations/membrane_transport/membrane_transport.htm
check out a blood cell in various solutions
Click on the link below to see how your red blood cells respond to hyper-, hypo-, and isotonic solutions:scroll down to Biology 12 and then click on the rectangle that says "red blood cells" in it(while you are there check out all of the other types of transport as well!)http://www.coolschool.ca/content/showcase.php?type=science
After organic compounds and cell transport will begin the cell itself and we'll use an old friend to help us along:
Greatest Discoveries with Bill Nye: Biology--Friday after your test!
Window panes
Your 4th set of Window panes won't be due until Wednesday! You get an extra Day. Why?
Because for the rest of the semester your window panes will be handled like a project. If you have been doing them correctly, you know how long it takes and will agree that they deserve to have more weight than a homework grade. I've decided that I will add them all together at the end of each grading period( not including the ones you have already done) and grade them as a project, just like the book you will be writing shortly!

Fourth list
window panes for Organic compounds:1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.11.Insulin- a hormone made in the pancrease that helps break down sugar in the body.12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).13. Glycogen- the stored form of glucose, it is stored in our liver.14.monomer- a molecule that exists by itself - only one molecule of something = glucose15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch16. Organic compounds- compounds that have the element carbon as the central/ essential connection.17. atom- smallest unit of an element.18. nucleotide- smalles functional unit (or piece) of a nucleic acid. It consists of a sugar, a phosphate and a nitrogen base.19. double helix- the shape of a DNA molecule, it resembles a twisted ladder.20. single helix- the shape of a RNA molecule, it resembles half of a twisted ladder.

this week and next week in biology
We are now moving from ecology to biochemistry, "the cell" and transport in and out of the cell.
This site should help with the cell and then again when we get to genetics.
It's a great site- I think you'll like the interactives!
http://learn.genetics.utah.edu/content/begin/cells/
check out the size comparison, the membranes and inside a cell.

third set of window panes (10)
biology terms for third set of window panes - due on Tuesday 9-14-10
biology terms1.Logistic growth- when a population of organisms grows at a steady pace until it reaches its carrying capacity, then it levels off. (graph with an s-curve)2.Exponential growth- when a population of organisms grows very rapidly because it has unlimited resources ( graph with a j-curve)3.Stewardship- when people take responsibility for their environment and do things to minimize the negative impact humans have on the environment- like a protector for the environment.4.Sustainable practices- using energy sources that are renewable and that don’t harm the environment. (wind power, hydroelectric power and solar power are examples of sustainable practices).5.Invasive species- organisms that currently live in an area they are not naturally found, they do not have any natural predators and can grow out of control- they usually take over the habitat of another organism that is normally found in the area. (examples are: fire ants, kudzu, rabbits in Australia, the cane toad, northern snakehead)6.Bioaccumulation- a build up of toxins in the tissue of an organism, top predators are most affected.7.Acid rain= http://www.epa.gov/acidrain/education/site_students/whatisacid.html sulfur dioxide and nitrogen oxides mix together to turn rain acidic- tree tops in the mountains look as if they have been burned8.Greenhouse effect- when Ultraviolet (UV) rays get stuck inside Earth’s atmosphere because a thicker shell of atmospheric gases has accumulated in the atmosphere due to pollution.9.Climate change- when the patterns of temperature and weather change over a large area due to the “greenhouse effect”10.Deforestation- when a large wooded area is cleared, either by “clear cutting” or burning, this results in greater amounts of carbon dioxide accumulation in the atmosphere.

Extra Credit guidelines
Here's what you do:
Watch a documentary that is "life science" based. While physics, astronomy and chemistry are useful and interesting, they won't help you in my class.
Examples of good programs are things you might find on National geographic, pbs, bbc, animal planet, planet green and the science channel. Many of these programs can be watched on your computer at your leisure.
You can complete four per each 6 week grading period.
You are basically summarizing what you watched. Write a sentence or two during commercials, or every 10 minutes if it's online, to describe what's happening in the documentary. At the end let me know the overall purpose or intent of the documentary and what you got out of it. It's meant to be a reflection on what you just watched.
TRY TO CHOOSE THINGS THAT WILL HELP YOU IN MY CLASS!
Topics we'll be covering in class: the cell, genetics, heredity, ecology, organic compounds, health and disease, classification of living organism, protein synthesis, plant structure and reproduction.
MAN VS. WILD is acceptable once every 6 weeks grading period. (NOT MYTHBUSTERS, sorry)
ANYTHING ON GENETICS IS GOLDEN!!!!! I MAY EVEN UP YOUR POINTS EARNED IF YOU CHOOSE THIS TOPIC!!
ENJOY!
Check out this site:
http://www.pbs.org/wgbh/nova/programs/int_natu.html

First window pane list
Here's your first homework assignment! Due Friday8/27
Go to my blogspot and print off your first list of window panes, bring in your list and show it to me on Friday!
First word list: (only 10 this time, next time there will be more)
Test on Scientific method Wednesday 9/1
Honors- First NPR assignment due Friday 9/3
http://www.sciencefriday.com/program/archives/201005141
Go to my blogspot and print off your first list of window panes, bring in your list and show it to me on Friday!
First word list: (only 10 this time, next time there will be more)
1.Observation- when you notice things about the world around you using your senses.
2.Hypothesis- Your opinion of why a certain thing is ocurring, an educated guess based on previous experience.
3. Data- Information you collect when running an experiment.
4. Experiment- an organized, controlled way of testing your hypothesis.
5.variable- something that can change in quantity or quality.
6. Independent variable- something you have control over and alter during an experiment. It's the thing you are testing! ONYL ONE variable can be tested at a time.
7. Dependent variable- the thing being measured in an experiment! It is the variable that changes as a result of you manipulating the independent variable.
8. Constants or Controlled variables- these are the things that have to remain unchanged and stable throughout your experiment. If they are altered at all then your experiment is not valid.
9. control group- the sample in your experiment that is not being exposed to the independent variable. This group lets you know whether the results you obtain from your experiment are from the independent variable or simply the result of something in the environment.
10. test group- the sample in your experiment being exposed to the independent variable. Bigger is Better! You want a test group to be as large as possible to make sure that the results you get are true and not a fluke.
These window panes are due Tuesday 8/31
Test on Scientific method Wednesday 9/1
Honors- First NPR assignment due Friday 9/3

Window pane terms
*** Additional things you need to know! CREATE WINDOW PANES OF THE FOLLOWING TERMS
1.Geographical Isolation- When organisms evolve into new species as a result of being isolated from other populations
2.Behavioral Isolation- Organisms that are similar to each other don’t mate because they don’t act the right way, this eventually leads to a new species.
3.Temporal/Reproductive isolation-When organisms that may be similar physically can’t mate because they don’t have compatible reproductive organs or perhaps they have different mating seasons.
4.Divergent evolution-When one species evolves into many different species to adapt to a new environment
5.Convergent evolution-When organisms with different ancestors evolve to have similar traits ( a bird has wings, a fly has wings but they have different ancestors)
6.Adaptive radiation- ( similar to convergent evolution so choose either one to do a window pane of, no need to do both) one species evolves rapidly into several different species to take advantage of different environmental resources. (Darwin’s Finches)
7.Gradualism- Evolution that occurs slowly over a long period of time.
8.Punctuated Equilibrium-Evolution that occurs rapidly due to some sort of natural disaster or other environmental reason
9.Vestigial structures- structures found in an organism that no longer serve a purpose. ( our appendix, our tail bone)
10.Homologous structures- characteristics which are shared by related species because they have been inherited in some way from a common ancestor. For example, the bones on the front fins of a whale are homologous to the bones in a human arm and both are homologous to the bones in a chimpanzee arm.
11.Analogous structures- characteristics are analogous (also called "convergent"), which means that they serve the same function in different species but they evolved independently rather than from the same embryological material or from the same structures in a common ancestor. An example of an analogous structure would be the wings on butterflies, bats, and birds.
1.Geographical Isolation- When organisms evolve into new species as a result of being isolated from other populations
2.Behavioral Isolation- Organisms that are similar to each other don’t mate because they don’t act the right way, this eventually leads to a new species.
3.Temporal/Reproductive isolation-When organisms that may be similar physically can’t mate because they don’t have compatible reproductive organs or perhaps they have different mating seasons.
4.Divergent evolution-When one species evolves into many different species to adapt to a new environment
5.Convergent evolution-When organisms with different ancestors evolve to have similar traits ( a bird has wings, a fly has wings but they have different ancestors)
6.Adaptive radiation- ( similar to convergent evolution so choose either one to do a window pane of, no need to do both) one species evolves rapidly into several different species to take advantage of different environmental resources. (Darwin’s Finches)
7.Gradualism- Evolution that occurs slowly over a long period of time.
8.Punctuated Equilibrium-Evolution that occurs rapidly due to some sort of natural disaster or other environmental reason
9.Vestigial structures- structures found in an organism that no longer serve a purpose. ( our appendix, our tail bone)
10.Homologous structures- characteristics which are shared by related species because they have been inherited in some way from a common ancestor. For example, the bones on the front fins of a whale are homologous to the bones in a human arm and both are homologous to the bones in a chimpanzee arm.
11.Analogous structures- characteristics are analogous (also called "convergent"), which means that they serve the same function in different species but they evolved independently rather than from the same embryological material or from the same structures in a common ancestor. An example of an analogous structure would be the wings on butterflies, bats, and birds.

Field Trip Info.
You may want to share some field trip info. with your parents, so I'm posting it here so you can do that.
* Field trip will be on 5/12/10 to Pisgah national forrest.
*We will leave at 7:00 am and return at 5:00 pm on an activity bus.
*You will have to pack your own lunch.
*We will be doing some walking/hiking so wear suitable shoes (if you aren't sure what is suitable for a walk in the woods, ask me during class).
*Remeber that we are going to the mountains, so just because it is 85 degrees here in Belmont, that doesn't mean it will be warm in the mountains. At the very least you must bring a sweatshirt!
* The trip will cost $30.00
*The $30.00 and the permission slip must be in to me by 5/7/10 or you won't be able to go on the trip.
* It might be buggy in the woods so consider bringing bug spray and a hat!

Guidelines for writing the book!!
OK, so you haven't had window panes for a couple of weeks now and the semester is wrapping up, you should have some time and energy to complete a make-up assignment to improve your grade!
Here are some guide lines for the Book project;
1. It must be 10 pages of content- that means illustrations with full sentences describing what is happening.
2. 2 pages of the 10 are your cover pages. This should be the easy part.
3. The Cover page needs to have your title, an illustration (drawing) , your name and your class on it!
4. The content you are covering in your book should be the same content you are trying to replace a grade for. Ex. If you did poorly on your mitosis test, your book should be about a cell going through mitosis or meiosis.
5. Your content must be represented in a logical way and should not be difficult for even a middle school student to understand. I don't need big scientific words, you may have to use some, but I'd prefer you simplify the process.
6. Label drawings or provide thought bubbles for your characters wherever you see fit. This information is considered Content!!!!
7. Be Creative- Try to create a main character that acts as a narrator and tells the story of protein synthesis, mitosis, meiosis, heredity or whatever topic you are missing!
Hand it in to me by Tuesday!!! 4/27/10
**Don't forget that you can definitely still do documentary write ups for extra credit! 10 points for every 2 hours. USe the Nova site and you can watch the documentaries any time (plus they are condensed so 50 minutes is = to a 2 hour tv documentary!!)
Good luck to everyone- Benchmark is next Tuesday!!

Biology word list 8
Word list 8
1. Genotype- the genetic code of an organism, usually expressed with two letters, one letter from Mom’s side and one letter from Dad’s side. ( BB or Bb would represent the genotype of a person with Brown hair or Brown eyes)
2. Phenotype- a physical trait that is the result of a person’s genotype, brown hair is the phenotype of a person who’s genotype is “Bb”.
3. Homozygous- when a person receives the same gene or allele from both parents (BB or bb).
4. Heterozygous- when a person receives two different genes or alleles, a different one from each parent. (Bb)
5. Zygote- the first 2N cell that is created from the union of the egg (1N) and the sperm(1N).
6. Dominant alleles- alleles that take over in a person, they are the stronger genes, they will show up physically even if another allele (recessive allele) is present in the genotype.
7. Recessive alleles- alleles that are present in a person but that don’t show up if a person also has a dominant allele for the same trait. Recessive alleles will only show up in a person if they receive the recessive allele from both parents – they must be homozygous (bb) recessive to have the trait show up in the person physically.
8. Co- dominant alleles- alleles that don’t have a winner- both traits show up a little bit, think about a spotted animal – like a brown and white cow or a black and white cat.
9. Incomplete dominance- when alleles don’t have a winner so they meet in the middle, think about a black cat and white cat making a grey cat, or red and white making pink!
10. Polygenic – when more than one gene contributes to trait in an individual. Skin color is a result of 7 different genes, that’s why there is so much variation- any girl who ever had to buy foundation can relate to this!

BIOLOGY TERMS FOR DNA AND MITOSIS
WORD LIST- for DNA and mitosis
1. Complementary base pairs- The nucleotides that fit together to form the DNA double helix, adenine with thymine and cytosine with guanine . Here is a visual, if the original strand of DNA has the following bases: A T C G A T T C G A T (ORIGINAL OR TEMPLATE)
Then the complimentary bases would be: T A G C T A A G C T A (COMPLIMENT TO THE ORIGINAL)
2. Replication- the process of copying the original strand of DNA to form a new, IDENTICAL, strand of DNA so that when the cell divides the daughter cells have the same exact genetic information as the parent cell.
3. Mutation- any change in someone’s strand of DNA, it could be a few letters (bases) or just one base.
4. Protein synthesis- using a cells DNA to code for and then make a specific protein needed by the cell, three types of RNA are needed to do this.
5. Trait- a physical characteristic or feature of a person (ex; brown hair, tall, diabetic, blue eyes)
6. Genes- the segments of a person’s DNA that code for a certain trait.
7. Transcription- when mRNA copies a segment of DNA in order to take the message out of the nucleus and to a ribosome. It must be written in the RNA’s language which uses Uracil in place of thymine for a nitrogen base. The uracil still pairs up with Adenine.
8. mRNA- messenger RNA is the RNA responsible for sneaking into the nucleus of a cell and copying off a certain piece of DNA and then carrying that piece of the code out to a ribosome.
9. Codon- three letters of a mRNA strand that determine which amino acid is to be made by a ribosome.
10. Translation- when the code made by the mRNA gets turned into an amino acid in a ribosome.
11. rRNA- is ribosomal RNA, it’s what makes up the ribosome and turns a codon into an amino acid.
12. tRNA- is the type of RNA that puts all of the amino acids in the correct order to form the proper protein. It has a complimentary RNA code for the newly produced amino acid to hook on to.
13. Polypeptide bond- it’s what connects one amino acid to another to make a complete protein.
14. Non-disjunction- When the chromosomes are not pulled apart evenly during anaphase of meiosis. This is what leads to Down’s syndrome (aka: trisomy 21 which means three of the 21st chromosome).
15. Chromosome- a condensed segment of DNA, humans have 46 chromosomes in every cell in their body,(except egg and sperm)
16. Chromatid- half of a duplicated chromosome- the whole X represents two sister chromatids!
17. Mitosis- the process of forming two new, genetically identical cells (skin, liver, hair, muscle, blood, etc. all of these cells are referred to as being 2N= the whole chromosome number, one set from Mom and one set from Dad)
18. Meiosis – the process of forming 4 new, GENETICALLY DIFFERENT cells with half the genetic material of the original cell. These cells only have 23 chromosomes (they are called 1N)
19. Zygote- forms when the egg and the sperm unite and make the first cell of a new organism.
20. Allele- a choice for a trait, you have two alleles for every trait in your body, one from mom and one from dad.

Word list 5 for Biology
1.Solute- any substance dissolved by a solvent.
2.Solvent- the substance used to dissolve a solute. (an easy distinction between solute and solvent is that there is always more of a solvent than a solute in any solution).
3.Solution- the mixture of a solute and a solvent; in salt water , salt is the solute and water is the solvent. *** WATER is known as the “Universal Solvent” for its ability to dissolve many substances.
The following terms relate to a cell ( a cell in your body) and the fluid it is floating in:
4.Osmosis- the movement of water from an area of greater concentration to an area of lesser concentration ACROSS a semi-permeable (some things can pass through and other things can’t/ kind of like a strainer in your kitchen) membrane (thin covering).
5.Isotonic solution- a solution that has the same amount of solute in it as the cell it surrounds - this results in NO overall or net movement of water (cell stays the same size).
6.Hypertonic solution- a solution that has more solute in it than the cell it surrounds- this results in water moving out of the cell and into the solution ( the cell shrinks).
7.Hypotonic solution- a solution that has less solute in it than the cell it surrounds- this results in water moving into the cell ( the cell swells).
8. Passive transport- the movement of a substance across the cell membrane (diffusion) that does not require any energy.
9. Active transport- the movement of a substance across the cell membrane-it REQUIRES ENERGY!
10. Facilitated diffusion /transport- the movement of a substance across a cell membrane with the assistance of a protein channel (door).

fourth set of window panes
window panes for Organic compounds:
1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.
2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).
3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.
4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)
5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).
6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.
7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)
8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)
9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.
10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.
11.Insulin- a hormone made in the pancrease that helps break down sugar in the body.
12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).
13. Glycogen- the stored form of glucose, it is stored in our liver.
14.monomer- a molecule that exists by itself - only one molecule of something = glucose
15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch
16. Organic compounds- compounds that have the element carbon as the central/ essential connection.
17. atom- smallest unit of an element.
18. nucleotide- smalles functional unit (or piece) of a nucleic acid. It consists of a sugar, a phosphate and a nitrogen base.
19. double helix- the shape of a DNA molecule, it resembles a twisted ladder.
20. single helix- the shape of a RNA molecule, it resembles half of a twisted ladder.
1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.
2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).
3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.
4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)
5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).
6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.
7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)
8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)
9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.
10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.
11.Insulin- a hormone made in the pancrease that helps break down sugar in the body.
12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).
13. Glycogen- the stored form of glucose, it is stored in our liver.
14.monomer- a molecule that exists by itself - only one molecule of something = glucose
15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch
16. Organic compounds- compounds that have the element carbon as the central/ essential connection.

tree poem
Joyce Kilmer. 1886–1918
Trees
I THINK that I shall never see
A poem lovely as a tree.
A tree whose hungry mouth is prest
Against the sweet earth's flowing breast;
A tree that looks at God all day,
And lifts her leafy arms to pray;
A tree that may in summer wear
A nest of robins in her hair;
Upon whose bosom snow has lain;
Who intimately lives with rain.
Poems are made by fools like me,
But only God can make a tree.

biology terms for third set of window panes
biology terms
1.Logistic growth- when a population of organisms grows at a steady pace until it reaches its carrying capacity, then it levels off. (graph with an s-curve)
2.Exponential growth- when a population of organisms grows very rapidly because it has unlimited resources ( graph with a j-curve)
3.Stewardship- when people take responsibility for their environment and do things to minimize the negative impact humans have on the environment- like a protector for the environment.
4.Sustainable practices- using energy sources that are renewable and that don’t harm the environment. (wind power, hydroelectric power and solar power are examples of sustainable practices).
5.Invasive species- organisms that currently live in an area they are not naturally found, they do not have any natural predators and can grow out of control- they usually take over the habitat of another organism that is normally found in the area. (examples are: fire ants, kudzu, rabbits in Australia, the cane toad, northern snakehead)
6.Bioaccumulation- a build up of toxins in the tissue of an organism, top predators are most affected.
7.Acid rain= http://www.epa.gov/acidrain/education/site_students/whatisacid.html sulfur dioxide and nitrogen oxides mix together to turn rain acidic- tree tops in the mountains look as if they have been burned
8.Greenhouse effect- when Ultraviolet (UV) rays get stuck inside Earth’s atmosphere because a thicker shell of atmospheric gases has accumulated in the atmosphere due to pollution.
9.Climate change- when the patterns of temperature and weather change over a large area due to the “greenhouse effect”
10.Deforestation- when a large wooded area is cleared, either by “clear cutting” or burning, this results in greater amounts of carbon dioxide accumulation in the atmosphere.

Physical science window pane terms for Wednesday
PHYSICAL SCIENCE TERMS:
Window pane terms for physical science- second list- chapter 1
(I’m reducing the amount you have to do to 15, I think the vocabulary is a little less intense in physical science than it is in Biology, so this is a permanent reduction to 15 terms a week).
*****remember to simplify the definitions- the examples are for your benefit, you are not expected to include them on the notecards.--- HAVE A GREAT WEEKEND AND “ LET IT SNOW, LET IT SNOW, LET IT SNOW”
1. standard- the exact amount people use to compare measurements.
2. SI units- these are the base units or standards used to measure different types of substances. (SI literally stands for Le Systeme Internationale d’Unites that’s French for international system of units). Ex. Meter, Gram, Liter, Second, Kelvin
3. Converting- when you change the units you have measured or obtained into different units, ex. Going from grams to kilograms.
4. Volume- the amount of space occupied by an object .
5. Mass- a measurement of the amount of matter in an object.
6. Density- is the mass of an object within a given space (volume). Explanation: a feather pillow in a normal pillow case is less dense than the same pillow that has been vacuum sealed in a plastic bag simply because it takes up less space but has the same mass! Sit with that one for a while!!!
7. Celsius scale- measures temperature using O degrees as the Freezing point of water and 100 degrees as the boiling point of water, your normal body temp. in Celsius would be 37 degrees.
8. Kelvin- the temperature scale used as the SI unit of measuring temperature. It uses the coldest temperature known as O degrees Kelvin- we call this “absolute zero” (in Celsius it would be -273 degrees , now that’s cold!!!
9. Line graph- a way to visually represent information that shows a change in one variable (dependent variable) as a result of the change of another variable (independent variable).
10. Bar graph- this is used to compare different amounts of items in different situations. We use this a lot when we compare EOC scores at the end of a semester – the different schools would be on one axis and the bars representing the number of students who are proficient would be on the other axis ( the bottom).
11. Circle graph – also known as a pie chart, shows how an overall quantity is broken down into smaller pieces. A home income can be broken down by monthly bills or other expenses.
12. Bias- when someone’s personal experience or feelings affects how data is collected and/or understood.
13. Technology- when science is used to help people.
14. Model- a representation of an idea, event or object that is used to increase a persons understanding of that idea, event or object.
15. Conclusion- after you analyze your data from an experiment you have to make a decision as to whether or not this data supports or disproves your hypothesis- this is your conclusion>

Biology & Physical science first word list- due Friday
1.Observation- when we notice something about the world around us using any of our senses
2.Inference-making a judgement about a situation or an event based on our previous knowledge and experiences.
3.Experiment- a means by which we can prove or disprove a concept, there are many parts to an experiment, all aspects must be documented and repeatable for it to be valid
4.Variables- things that change in an experiment
5.Independent variable- the piece of the experiment that you control and that you are testing
6.Dependent variable- the thing that you are measuring in the experiment, it's the part that will change as a result of what you did with the other variable.
7.data- the information that you gather from your experiment, it must be orderly and accurate for the experiment to be valid.
8.control group- a group in the experiment that is set up the same way as the group you are testing, only you leave this group alone, this way you will know if the changes in your experiment were a result of your action or just a coincidence.
9.constants- these are the things that you leave the same for all groups in the experiment, all aspects of your experiment must be exactly the same (constant) for each group, otherwise you won't know for sure what caused the changes in your test group. *** you only test one variable at a time.
10. conclusion- after you analyze the data collected from the experiment, you decide whether or not the experiment supported your "hypothesis".

HEy- if you are trying to cram for the EOC don't forget to look at the other released testing items, go to this site: http://www.dpi.state.nc.us/accountability/testing/eoc/sampleitems/5
also do the regents test prep site.
FYI- your endocrine system (pancreas and spleen) is responsible for making hormones and insulin!
FYI- Gymnosperms reproduce using cones= pine trees
Angiosperms are broken down into two types of flowering plants Monocots (grass- parallel veins) and dicots ( apple tree- netted veins)
Monocots and dicots refers to how many cotyledons grow out of the seed- monocot= one cotyledon, dicot= two cotyledons!
oh- HI Ashley!!
