11. How does a lack of insulin prevent the cell from using glucose? 12. Why is it important that specific tissues respond to insulin in different ways? 13. Hypothesize a mechanism to explain how tissues respond to insulin in different ways, even tissues that have the same amount of the receptor.

Answer in no more than 500 words.
Chordates are characterized by having a dorsal hollow nerve chord, a notochord, and a tail. Some years ago, researchers discovered that in Tunicates, a single mutation in one gene caused the nerve chord, the notochord, and the tail to all disappear. A writer for Science magazine concluded from this that all three definitive chordate traits must have evolved at the same time, with the appearance of this gene. Explain the flaw in this reasoning.

Why is descent with modification not sufficient to explain the variation in life forms (bacteria, whales, crabs, insects, etc.) we see today?

Describe the structure of IgG in detail by referring to the different levels of protein structure

Explain the allosteric regulation of hemoglobin by BPG, by referring to the structural changes in hemoglobin induced during binding

1) What are IP Cells and Stem Cells with respect to cell death and renewal?

1. Specify the vitamin(s) you think are generally hard to get enough of (i.e., to meet the RDA for that vitamin) in the United States and explain why.
2. Specify the consequences that could result in individuals or in the United States overall if the RDA for this/these vitamin(s) is not met.
3. Do you think you are generally getting adequate amounts (i.e., meeting the RDA) of the vitamin(s) you identified? Why or why not?

Evolution, in the biological sense, is NOT described by which of the following?

A. It is defined simply as change over time.

B. It is genetic change in populations over time.

C. It requires genetic variation in the population.

D. It requires differential survival of individuals based on genetic factors.

E. It is described by all of the above.

Advantages of studying molecular variations include all of the following EXCEPT:

A. molecular data directly reflect genetic differences.

B. molecular data can be used to compare organisms of different species.

C. molecular data can be quantified.

D. molecular data can be collected easily.

E. Actually, all of these are advantages to studying molecular rather than phenotypic variation.

Clindamycin binds to the 50S ribosomal subunit of bacteria. Using this information, respond to the following:

a. Referring to the 5 modes or mechanisms of actions of antibiotics, which one applies to clindamycin?

b. Is this a broad or narrow spectrum antibacterial agent? Explain

c. Does clindamycin have selective toxicity for bacteria? Explain

1) Explain how the body metabolizes carbohydrates and protein in the fed state.

2) Explain how the body metabolizes carbohydrates and fat in the fed state.

3) Explain how the body metabolizes carbohydrates and amino acids in the short term fasting states (prior to using up all your glycogen).

4) Explain how the body metabolizes fats in the fasting state once you have used up all your glycogen stores.

write an improved experimental design to test the hypothesis “If blue light is more effective at promoting photosynthesis, then more oxygen gas (O₂) will be produced when plants are exposed to blue-filtered light compared to other wavelengths.”
