pictures for poster on classification

your poster will contain information on all of the 6 kingdoms as well as many of the phyla under each kingdom. Pictures of the following organisms will be helpful, remember you want smallish pictures because you have a lot to fit on your poster :)

ALSO- your poster is your guide map through your test, the more complete your poster is in terms of information, the better you'll do on your test- your team may use the poster at their table, however, you will not be able to help each other- different tests for each of you and NO TALKING.


Animals:  worm, sponges, jellyfish (aka Cnidaria), molluscs ( clams, etc), arthropods, insects, fish, amphibians, birds, reptiles mammals.
Plants: moss, ferns, gymnosperms and angiosperms
Fungi: mushrooms
protist: single celled eukaryotic organisms like- amoebas, parmecium, euglena and diatoms

Extra credit info (AGAIN)

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.

GO here to watch online ( Nova and Nature are best!)
http://video.pbs.org/
INCLUDE your name, the documentary title, the length of the documentary.

2hours on tv =50-60 min. on computer= 10pts
1 hour on tv = 25-30 min on computer = 5pts.

you can earn up to 40 points per 6 weeks!


Write a few sentences 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. (just a few sentences will do!)

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

HOT ZONE!



By December 2nd, you should be through part one of the Hot Zone- that means you have read pages 1 -153.
Ebola Virus



You will be tested on each section of the book (there are four)- the test questions will focus on the biology aspects of the study guide. Questions that are plot oriented or relationship oriented will not be asked

Here is a link to the guided questions that go with the first section:

Blood type info! look it over.

HOW'D YOU GET THAT BLOOD??
http://learn.genetics.utah.edu/content/begin/traits/blood/

HONOR'S KIDS- RE- WRITTEN CHILDREN'S BOOKS ARE DUE MONDAY- USE YOUR TIME WISELY THIS WEEKEND!!!!

Heredity word list- due Wednesday 11-9-11

1.Zygote- the diploid cell formed by fertilization of an egg cell- it's basically the first cell of a person, the egg and sperm DNA unite to get back to that 46 chromosome number, the zygote replicates (mitosis) and becomes YOU! YOU with half of your DNA from Mom and half from dad- two bits of info. for nearly every trait in your body. 2.ALLELE- a segment of your DNA (or gene)that codes for a trait in your body. You have two alleles for every trait in your body (with one exception- naturally!). 3. Homozygous alleles- this is what we call the genetic situation when both parents give the same information (genes) for a trait. For example: both of your parents give you the gene for blonde hair, you have no other choice than to have blonde hair. 4. Heterozygous alleles- this is what we call the genetic situation when your parents give you two different genes for a trait. For example: Your Mom gives you the gene for brown hair and your dad gives you the gene for blonde hair- now your Genome has to decide which proteins to make- ones for brown hair OR ones for blonde hair- who will win? read on to find out! 5. Dominant traits (or alleles or genes)- This is when one of the alleles from a parent is stronger than the allele from the other parent so it's the one you use and, therefore,it's the trait that you have. Brown hair is dominant to blonde hair, therefore, you will have brown hair and you won't even know that you have a secret hidden gene from your other parent! (you can probably figure it out though- either by what your parents look like or what your kids look like) We only use one letter to represent a trait when we are trying to predict what traits a person will have, the Dominant trait determines what the letter will be and it (dominant one) will be uppercase- the recessive trait will use the same letter as the dominant trait, but we show that it is recessive by making it lower case! 6.Recessive traits (or alleles or genes)- This is when one of the alleles you get from a parent is weaker than another. You don't use this gene because you favor the stronger gene. In this way it is a hidden, secret gene, that you may never know you have. Even though you don't use this gene in your body, you do have the potential to give this "recessive" gene to your children and (depending on how the shuffling goes during meiosis) they could end up having that recessive trait. EVER see two brown headed people with a blonde baby- their baby- they both had a recessive allele for blonde hair!!!!!! 7. Co-dominant alleles- this is when you have heterozygous alleles for a trait (that's two different alleles) and they are equally strong so they both show up!! This is how you get stripes and spots in fur- neat,hugh? 8. Incompletely dominant alleles- this is when you have heterozygous alleles for a trait (that's two different alleles) and they are equally strong, so they duke it out and decide to compromise- they meet in the middle- you no longer see the original traits but a medium version of each trait- think Pink! As in: Red mixed with White makes PINK! 9. Genotype- this is how we refer to the "letters" or alleles you carry- you always have two- one from mom and one from dad. TT or Tt where "T" is tall (dominant) and "t" is short (recessive). 10. Phenotype- this his how we refer to the visible PHYSICAL features that result from your alleles - "Tall" or "Short". It's what we see and know you have with and/or without knowing what your DNA says. 11.Gregor Mendel- a Monk/ gardener that figured out "genetics" using pea plants. He just cross pollinated pea plants that had different colored flowers and figured out the whole dominant/ recessive trait thing. Genetics that deals with only dominant and recessive traits is even called "MENDELIAN GENETICS". 12. HYBRID- this is how we sometimes refer to the crossing (or breeding) of two different different organisms of the same species. YOU are a hybrid of your parents!!! when we are crossing to test one trait it's refered to as a monohybrid cross ( two traits would be a dihybrid cross) 13.Punnett square - you may have used this tool in Math class- it's how we set up a cross between two different individuals to get the probability of a given trait(s) appearing in their offspring. We use the letters that represent the trait to complete the punnett. go here to see how this is done!!!!!! DON'T look at dihybrid stuff- too confusing for you now. http://www.athro.com/evo/gen/punnett.html practice: http://www.athro.com/evo/gen/punexam.html overview of genetics: http://www.google.com/search?sourceid=navclient&hl=en-GB&ie=UTF-8&rlz=1T4GGLJ_en-GBUS290US290&q=punnet+square+introduction it's the first link- it's a ppt.

How to make a protein- paragraph

In order to make a protein you first have to have a template for the protein you want to make. DNA is the template, it is made up of Adenine, Thymine, Cytosine and Guanine and is in the shape of a double helix, it is only found in the nucleus of a cell. When a protein is needed mRNA gets a signal to transcribe the DNA message for that protein. It does this by opening up the DNA and putting it into mRNA letters, mRNA uses Uracil instead of Thymine in its code. mRNA then leaves the nucleus, it enters the cytoplasm and finds a ribosome. The ribosome is made of rRNA and is capable of reading the mRNA. It reads the mRNA in a sequence of 3 nitrogen bases (codons) at a time. each codon represents an amino acid. The tRNA gets the signal from the ribosome to go pick up the proper amino acid that was coded for by the mRNA, it brings the amino acid back to the ribosome and places it where it belongs by using the anti-codon. The amino acid is then bonded (peptide bond) with the other amino acids to create a specific protein!!! (.." the code gets translated, acids are created, then proteins are made-hip,hip, hurray!!!!

Good LUCK!!
