3. Explain why radioisotopes are important to biologists.
4. Distinguish among covalent, ionic, and hydrogen bonds.
5. Explain why weak bonds are important to living organisms.
6.Describe the structure and geometry of a water molecule, and explain what properties emerge as a result of this structure.
7. Explain the relationship between the polar nature of water and its ability to form hydrogen bonds.
8. List five characteristics of water that are emergent properties resulting from hydrogen bonding.
9. Explain how the polarity of the water molecule makes it a versatile solvent.

Assignments:

1.Study week 6 Scientific words.
2.Read pg. 148 - 155 in the new textbook. We have already gone over these concepts.
3. Complete your Drosophila lab report. This is due Tuesday!! Below is the format that you should be putting your lab in.

4. Sections 3 and 4 of the Science Notebook. Fill in the answers in the notebook that you were given on Tuesday. It was green and had Science Notebook on the cover. Due Friday so we can go over it and you have it to help you study for your test Monday
5. We will do this lab Thursday and Friday of next week. It will be due Monday when you enter class. You will be responsible for turning in any observations, data tables, and conclusion or analysis questions. This has been posted on your homework assignments on the mcgraw hill account as well

6. Study for your TEST!!
