1/6 Biology update and homework due 1/13

Hi folks,

Today we dove a bit more into the nitty gritty of evolution and investigated a simulation that allowed us to manipulate the evolution of a population of strange creatures.  We also had a fascinating discussion about whether or not humans are evolving.  

For homework this week I'd like to take the time to review much of what we've covered throughout the year so far.  Please do all the following questions and be sure to study them because they will probably be on an upcoming quiz.

1.  What is the definition of hydrophilic?

2.   What is it about water that makes it polar?

3.  Draw the following functional groups.

a.  Amino

b.  Hydroxyl

c.  Phosphate

d.  Carboxyl

4.  Draw the 4 biological molecules.

5.   Give four examples of homeostasis.

6.    What does mRNA do?

7.  What does tRNA do?

8.  What is transcription?

9.  What does DNA Polymerase do?

10.  What does smooth endoplasmic reticulum do?

11.  What does rough endoplasmic reticulum do?

12.  What do chloroplasts do?

13.  What does the vacuole do?

14.  What do mitochondria do?

15.  What are two differences between plant and animal cells?

16. What are two differences between a prokaryotic and a eukaryotic cell?

17.  What three things do all cells have in common?

18.  What are the 4 bases in a DNA molecule?

19.  Which base pairs with which base?

20.  Which base is missing in RNA?

21.  What is the difference between a trait and an allele?

22.  What is co-dominance?

23.  What is incomplete dominance?

24.  What's the difference between hydrophobic and hydrophilic?

25.  Draw and label the steps in meiosis.  Describe the two places where genetic shuffling takes place.
