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.

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.

11. A strawberry farmer determines that the average weight of individual strawberries produced by plants in his garden is 3 g. He selects the 10 plants that produce the largest strawberries; the average weight of strawberries among these selected plants is 6 g. He interbreeds these selected strawberry plants. The progeny of these selected plants produce strawberries that weigh 4 grams.
If the farmer were to select plants that produce an average strawberry weight of 7 g, what would be the predicted weight of strawberries produced by the progeny of these selected plants?
