Introduction:
After looking over the schedule and table of contents in your textbook, either:
Write down one question, or topic, or idea pertaining to Biology that you would like to see discussed in this class.
Or
Write down one topic of Biology that confused or did not make sense to you in your high school (or most recent) biology class.
Due 8/20/09

Chapter 1:
Thinking Through the Concepts, Questions 2 and 5.
Due 8/25/09.

Chapter 2:
The lizard in the beginning of this lecture appears to be running on water. Aside from the speed at which the lizard runs, what property of water allow the lizard to move like this? How does this property work (i.e. describe the arrangement of molecules)? Give one example where this property of water is used in nature.
Due 8/27/09.

Chapter 3:
Thinking Through the Concepts, Question 5.
Due 9/01/09.

Chapter 4:
Read the article and animation by Keiichi Namba on the Prokaryotic flagella (posted in the "Assigned Articles" section of the webpage), and the section in your book titled "Cilia and Flagella Move the Cell Through Fluid or Move Fluid Past the Cell" with Figure 4.7 and 4.8 (page 66 and 67 in the Ventura College edition) on the Eukaryotic flagella.
Compare and contrast how the Prokaryotic and Eukaryotic flagella are made and organized, and how they move a cell. Be sure to discuss one thing unique about each structure.
Due 9/10/09.

Chapter 5:
Thinking Through the Concepts, Question 2.
Due 9/15/09.

Chapter 6:
Thinking Through the Concepts, Questions 4 and 5.
Due 10/6/09.

Chapter 7:
Thinking Through the Concepts, Question 3.
Due 10/13/09.

Chapter 8:
Thinking Through the Concepts, Question 6.
Ignore any discussion of Chemiosmosis.
Due 10/20/09.

Chapter 9:
A. What types of mutations can occur during DNA replication that result in a DNA strand of the same length as the template strand?
B. Assume that in the process of creating a replication bubble during DNA replication, the helicase causes a substitution in the complimentary strand only. The mutation was not caught by proof-checking machinery and replication continued.
After two rounds of DNA replication (this first replication bubble starts the first round), how many strands of DNA carry the mutation (each half of the DNA double helix counts as one strand)?
Due 10/29/09.

Chapter 10:
Complete this worksheet.
Due 11/5/09.

Chapter 11:
Mitosis and Meiosis are essentially identical except for two stages of cell division.
a. What are those two stages?
b. What happens to the chromosomes in these two stages (from part a) during the three types of cell division: Mitosis, Meiosis I, and Meiosis II?
Due 11/17/09.

Chapter 12:
Calculate the genotypes, genotype ratios, phenotypes, and phenotype ratios of the following breeding experiments:
a. Heterozygous brown eyes crossed with Homozygous Recessive blue eyes.
b. Heterozygous brown hair and Homozygous Recessive blue eyes with Homozygous Recessive blonde hair and Heterozygous brown eyes.
c. Homozygous Recessive blonde hair and Heterozygous wavy hair with Heterozygous Brown hair and Heterozygous wavy hair.
(Note that hair texture exhibits incomplete dominance with curly hair dominant and straight hair recessive)
Due 11/24/09.
