Answer to Question 1

A
Feedback:
That the rate of cell death is genetically programmed is a basic tenet of the programmed theory of aging. That the aging body produces fewer growth and repair hormones is a neuroendocrine theory. Although radiation and heavy metals may damage DNA, they are not free radicals, and they need not be the cause of the mutations assumed by the error theory.

Answer to Question 2

B
In dermatitis venenata (poison oak or ivy), the patient should wash the affected part immediately after contact with the offending allergen.
