APES And Biololgy work to do at home!

APES:

We will be using this site for the ecology unit
http://www.learner.org/courses/envsci/unit/text.php?unit=4&secNum=0

You should go ahead and start by viewing the 28 minute video that goes with the unit.
http://www.learner.org/courses/envsci/unit/text.php?unit=4&secNum=1

Here is the link to the document that accompanies the video- please fill it out in as much detail as possible- you can make a copy of the document and then type in your answers, or just print it off and complete by hand!
https://docs.google.com/document/d/1LRqZWa4h_oY3gzKAIU-0eXrYvF3M81qLwSCvSbCJjgM/edit?usp=sharing
* I'm still working on the study guide to accompany the reading, so check back later for that-Thurs. night??


After that you should proceed through each section 

I'll have a study guide for you but you should go ahead and start reading through each section!

These snow days won't change the date of the AP exam so we can't get any further behind. 
You should be spending at least 2 hours a day on any AP class you are taking! 
Usually we can handle the majority of what should be covered during class time, but when we have days like this you have to step up and do your part at home.


Biology- Do this prior to Friday's class! 
YOUR NEXT TEST WILL BE ON CELLS- THE CELL CYCLE, MITOSIS, MEIOSIS, STEM CELLS AND ORGANELLES.

USE KAHN ACADEMY TO HELP YOU WITH THIS MATERIAL!
Watch the following videos, sketch out the process as he goes through it! Take notes, pause as needed to make sure you understand what is going on. This may take you a while, you may have to watch them twice to understand it.DON'T PUT IT OFF TO THE LAST MINUTE
I will check your notes/ sketches!

mitosis- about 20 minutes
https://www.khanacademy.org/science/biology/cellular-molecular-biology/new-topic-2014-06-18T18:00:45.081Z/v/phases-of-mitosis

meiosis- about 27 minutes

Biology window panes- cell division due Feb. 25th

Window panes for cell division! These will be due Wednesday Feb. 25th
1. 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).
2. Chromosome- a condensed segment of DNA, humans have 46 chromosomes in every cell in their body(except egg and sperm).
3. Chromatid- half of a duplicated chromosome- the whole X represents two sister chromatids held together in the middle by the centromere!
4. 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)
5. 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 1 N)
6. Zygote- forms when the egg and the sperm unite and make the first cell of a new organism- the zygote is 2 N because the DNA from the egg and the sperm are now together in one cell, it will now undergo rapid mitosis to form a blastula and eventually- YOU!
7. Allele- a choice for a trait, you have two alleles for every trait in your body, one from mom and one from dad.
8. 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.
9. Trait- a physical characteristic or feature of a person (ex; brown hair, tall, diabetic, blue eyes)
10. Genes- the segments of a person’s DNA (or chromosome)that codes for a certain trait.
11. Fertilization- when the sperm cell unites with the egg cell.
12. Centromere- the structure that holds two sister chromatids together.
13. haploid- The “Half” number of chromosomes an organism would have in a regular/ non- sex cell. Sex cells are haploid!!!! (same thing as 1N)
14. Diploid- The full chromosome number in a regular/somatic cell, the prefix “di” relates to the fact that you have “two” bits of information (chromosomes) for nearly every trait in your body. One from Mom and one from Dad. (same thing as 2N)
15. Somatic cells- all of the cells in your body except for your egg or sperm cells.
16. Gametes- the cells in your body that participate in reproduction, either egg or sperm cells.
17.Homologous chromosomes- The chromosomes that Match up for given traits, the chromosome from Mom that codes for height and the chromosome for Dad the codes for height are “homologous”. They pair up during meiosis one and trade information to insure that offspring are not identical!
18. Crossing over- when homologous chromosomes pair up and trade genes during meiosis one.
19.sexual reproduction- when organisms use meiosis to allow for genetic variation of offspring- this allows for increased chances of survival in a species.

20. asexual reproduction- when organisms use mitosis to duplicate their cells, this results in a “clone” or two identical cells. Your cells do this when you are growing or repairing damaged tissue. Some organisms do this to make offspring= bacteria (called binary fission) and fungal spores do this.

Biology window panes due Feb 11th


Next set of window panes due Wednesday, February 11th :
Remember- 4 to a page, color the illustration, give an example and opposite for each.

1. Chloroplast- organelle found only in plant cells, it makes chemical energy (sugar/ glucose) using solar energy (sunlight) to combine water and carbon dioxide.
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. Active transport- transport of a substance across the cell membrane that requires energy!! When something moves from where there is less of a it t0 where there is more of it. This usually takes work. Imagine you are trying to push the last little bit of a sleeping bag into it's case.
10. diffusion or passive transport- transport of a substance across a cell membrane, this type does not require energy because the substance is usually small, like oxygen, and moving from where there is more of it to where there is less of it (with the concentration gradient). imagine a ball rolling drown a hill - from where it is highest to where it is lowest- no energy needed.
11. facilitated diffusion- this is a lot like passive transport in that it doesn't require energy. It does however require a door called a protein channel. this is because the substances are usually large, like a sugar molecule. These substances move with the concentration gradient (high to low) as well.
12. Osmosis (or diffusion of water)- is the movement of water (only water) across a cell membrane- this works with the concentration gradient as well, moving from where there is more water to where there is less. It does not require energy! ** note- water usually follows salt! If you've ever eaten too much salty popcorn at the movies you may have noticed that your hands get puffy. Your cells are soaking up fluids to balance out the salt in your cells. this is an example of how your body carries out homeostasis.
13. Fluid mosaic model- this refers to the way your cell membrane is made, it is made up of two floating layers composed of proteins and lipids. the membrane is constantly moving which allows substances to glide through it. the lipid layers insure that the water level in your cells is controlled- the inside lipid (fat)Layer holds the water in, the outside lipid (fat) layer keeps water out. the protein channels are like tunnels that take substances from one side of the cell all the way across both layers to the other side of the cell.
14. Eukaryotic cells- have membrane organelles, in particular a nucleus that holds its DNA. Animals, Plants, Fungi and Protists are made of these types of cells. They are thought to be a symbiotic relationship between cells that were once prokaryotic.
15.Prokaryotic cells- Do not have membrane bound organelles. They have DNA, but it is not kept inside of a nucleus, it is in the shape of a plasmid (circular) that floats around in the cell. ONLY BACTERIA are Prokaryotic
16. Euglena- a photosynthetic organism that lives in water. It has Chloroplasts and other organelles and is a unicellular (one celled) organisms made of cells like us- Eukaryotic! (It is a protist)
17. Paramecium- a one celled organism (protist) that swims (it also lives in water) using its cilia. It eats other organisms to survive.
18. Contractile vacuole- organelle in protists that helps them maintain proper water balance by helping to pump out excess water. They need this since they live in the water.
19. Plasmid- a circular strand of DNA found in bacteria.
20. Golgi body- organelle responsible for packaging substances made or excreted by your cells.

APES Wednesday night homework Biology window panes due tomorrow!


APES

Watch this TED talk:
https://www.youtube.com/watch?v=8Q1VnwcpW7E

take notes- you'll need them :)


Due tomorrow for Biology:
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
