Overview of Chapter 1 and Chemistry Review

Today we spent 15 minutes answering questions from chapter one (mainly on the difference between prokaryotes and eukaryotes as well as the difference between food webs and chains).

Students completed a chemistry reivew (see below)

1. Does having a basic understanding of chemistry help when it comes to learning biology? Explain your answer using no more than 5 sentences.
   

2. What six elements are most common in living matter? (2.2)

3. List any three compounds in the human body. (2.3)

4. Explain and give an example of an isotope. (2.4)

5. How many covalent bonds does H, O, N, C and S make? (2.6)

6. Draw the electron configuration for the following elements: Na & Cl. (2.6/2.7)

7. Explain and give an example of an ionic bond. (2.7)

8. Explain and give an example of a covalent bond. (2.8)

9. What is chemically nonsensical about this structure? (2.8) H---C==C----H

10. Water is kind of a big deal in biology. Tell me everything that you know about water that you consider relevant. (2.9-2.14)

11. Based on what you know about pH, make a prediction about the role that pH plays in living systems. (2.15-2.16)

12. The relationship between structure and function is a theme that is central in biology. Describe the relationship between structure and function using any molecule of your choice.

We discussed the importance of spring turnover in aquatic ecosystems and what happens when a thermocline occurs as well as what happens at the molecular level for acid reflux.

Homework: (all blocks) If there were any questions that you are still having trouble with look at that section in the book. The numbers parentheses at the end of the question correspond to the section in the book.

C block: you do NOT need to wear closed toed shoes to lab tomorrow. All other labs you will need to wear closed toed shoes.
