Bring index cards to class so you can get them done!

Window panes are due prior to the test on Friday, 12-4-09. (hand them in with your study guide)
window pane terms:
1. evolution- the concept that organisms change over time.
2.Abiogenesis- the concept that life arises from non-living organisms
3.Biogenesis- the concept that living things can only come from other living things.
4.biochemical evidence- using an organisms chemical make-up ( genetic code and proteins) to show how related they are to other organisms.
5. Homologous structures- when organisms have similar skeletal structures that have different physical functions ex., a bat wing and a whale's fin or a frogs foot and a chimps foot.
6.Vestigial organs- structures in our body that do not serve a purpose, remnants of our ancestors. ex. appendix and tailbone
7.acquired traits- traits that you obtain in your lifetime- these are not evolved traits- learning to play an instrument, or losing a limb.
8. natural selection- when organisms evolve as a result of who they chose to reproduce with, over time (millions of years) this results in a new species.
9. adaptive radiation (syn= divergent evolution) - When new species develop from one common ancestor as a result of some sort of isolation.
10.convergent evolution (ant= divergent evolution) - when organisms from different ancestors evolve to look similar because they are adapting to a similar habitat.
11.coevolution- when organisms evolve together, flowers and pollinators do this.
12.speciation - the process of developing into a new species
13.reproductive isolation- when two similar organisms cannot reproduce together due to physiological reasons or having different mating seasons
14. behavioral isolation - when two similar organisms don't reproduce together because of one having an inappropriate or different behavior.
15.Geographical isolation - when two similar organisms don't reproduce together because they are separated by some geological barrier.
16.disruptive selection (use the graph for your drawing)
17. stabilizing selection (use the graph for your drawing)
18. directional selection (use the graph for your drawing)
19. gradualism
20. punctuated equilibrium

HONORS Biology

complete the SAS #52 by Friday December 4th
I will stay late on Tuesday and Wednesday so you can use the school computers if necessary!

Evolution material

go here to watch or re-watch PBS (Nova) videos on evolution and to help you answer the questions on your study guide.
http://www.pbs.org/wgbh/evolution/educators/teachstuds/svideos.html

Here's another copy of the study guide ( for anyone absent or anyone who lost it), you will have to turn in your completed study guide, as well as your completed window panes on Friday prior to your test.

Nova:
Answer or define the following:
1. What is a theory?
2. What is an inference?
3. What is the theory of evolution?
4. Who developed the theory of evolution through natural selection?
5. What does a paleontologist study?
6. What did the common ancestor (that walked on 4 legs) of the whale look like?
7. What structures on the whale are similar ( aka -homologous structures) to structures on a chimp, frog and bird?
8. How does natural selection work (there are 4 points)?
9. What adaptations did the hummingbird have that made it more successful?
10. What evidence is there to support the theory of evolution?
11. Explain how using antibiotics leads to the evolution of new bacteria?
More things you need to know: ( use chapters 14 and 15 in your reading essentials to answer these questions)

1. What mechanisms (3) lead to the development of new species (aka-speciation)?
2. What did the first living organisms on earth look like?
3. What conditions existed on the earth when the first life forms existed?
4. Where the first organisms aerobic or anaerobic? Why?
5. What are:
Directional selection

Disruptive selection

Stabilizing selection

Artificial selection
6. What are homologous structures?
7. What are analogous structures?
8. What is divergent evolution?
9. What is convergent evolution?
10. What type of evolution is slow?
11. What type of evolution is fast?
12. What is the theory of abiogenesis?
13. What is the theory of biogenesis?
14. How do pesticides and herbicides lead to the evolution of new species?
15. Adaptations can be good or bad, give examples of both.
16. Who was Francesco Redi? Explain his experiment.
17. Who was John Needham?
18. Who was Lazzaro Spallanzani? How did he perfect Needham’s experiment and what did it prove?
19. Who was Louis Pasteur and what did he do differently to help lay the issue to rest permanently?
20. Give an illustration of what Pasteur’s experiment looked like?

genetics test

go to this site and review EOC questions goal 2 up to #17.
http://www.dpi.state.nc.us/docs/accountability/testing/eoc/sampleitems/bio/20080109biog3.pdf
know your blood typing, X-linked and regular punnett squares.

Blood typing giving you a headache?

try going here to get it all cleared up.


Check out the 2009 nikon photomicrograph winners, this is a picture of ciliated protozoans.
What do you think the blue stuff is?
