Answer to Question 1

C
Feedback:
Studies of in vitro cell proliferation have demonstrated that various species have a finite number of cell divisions. Life spans of parents and offspring are positively correlated. Mutation perpetration is a tenet of the error theory, not the programmed theory, of aging. Although longer life spans correlate positively with numbers of cell divisions in vitro, the rate of cell division is not affected.

Answer to Question 2

D
Tinea corporis is known as ringworm of the body. It occurs on parts of the body with little or no hair.
