B)They attempt to explain aging at the cellular level.
C)They discount the role of genetics in aging.
D)They emphasize the effects of ecological factors on aging.

Question

Quizplus · Accepted Answer

All three theories attempt to explain aging at the cellular level. The cellular clock theory suggests that cells have a limited number of divisions before they can no longer divide, the free-radical theory proposes that aging is caused by damage to cells and tissues by free radicals, and the mitochondrial theory suggests that dysfunction in the mitochondria can cause aging. None of the theories discount the role of genetics or attribute aging purely to hormonal changes or ecological factors.
