1. Which of the following functions of vitamin B-12 is not related to the functions of folate?

A. Maintaining myelin sheaths

B. Transfer of methyl groups

C. Homocysteine metabolism

D. DNA synthesis

2. Plants _______.

A. are a rich source of vitamin B-12

B. are not sources of vitamin B-12

C. contain about the same amount of vitamin B-12 as is found in animal foods, such as liver

D. can make vitamin B-12 in the presence of folate

3.With excessive intakes of vitamin C, increased urinary excretion of ______ (a by-product of vitamin C metabolism) may cause kidney stone formation in susceptible individuals.

A.oxalate

B. pyruvate

C. phosphate

D. uric acid

4.Which have vitamin-like compounds that have antioxidant functions in the body?(select those that apply)

A.Taurine

B.Choline

C.Carnitine

D. Lipoic

E. Inositol

5. Why are older adults at increased risk for vitamin B-12 deficiency compared to younger people?

A. As you age, your macula begins to turn yellow—a sign of excessive folate absorption, which masks vitamin B-12 deficiency.

B. As you age, your metabolism slows and a rapid metabolism is required for optimal vitamin B-12 absorption.

C. As you age, your bones become more porous; porous bones do not absorb vitamin B-12 as well as dense bones do.

D. As you age, your stomach produces less acid, which limits cleavage of vitamin B-12 from food. In addition, decreased production of intrinsic factor by the stomach limits vitamin B-12 absorption.

Scientists genetically modified a specific subspecies of fruit flies to ensure there are no mutations when DNA replicates. The scientists state this modification will wipe out any genetic variation in these particular modified flies. The second set of scientists make the claim that getting rid of errors during the S phase of mitosis will not entirely get rid of genetic variation in these fruit flies your job is:

Explain how does variation leads to this population's evolution?

Please be specific and thorough as possible, I will give a thumb up if I like your answer. Thank you.
