Answer to Question 1

ANS: A
Cross-links form in elastin in connective tissue. Elastin is similar to collagen in that it main-tains tissue flexibility and permeability. The effects of cross-linking in elastin fibers are most pronounced in the changes that occur in facial skin with aging. Skin becomes brittle, dry, and saggy, and it appears translucent. Applying appropriate moisturizes helps minimize the ef-fects. Genetic history is relevant to the genetic theory of aging. Exposure to environmental toxics applies to the biological theory of aging. Vitamin A, C, and E consumption related to the free-radical theory of aging.

Answer to Question 2

ANS: B
Explicit memory, which is the ability to recall a specific name or place, tends to decline with aging. Working memory, which is the type of memory that is needed to perform daily activi-ties, does not show an aging decline.
