Question

Quizplus · Accepted Answer

Programmed theories of senescence claim that aging follows a predetermined plan, while unprogrammed theories attribute senescence to environmental factors such as wear and tear or accumulated damage. The answer is not D because programmed theories do not rely on computer models to predict senescence in a given species, and the answer is not A because unprogrammed theories do not exclusively attribute senescence to environmental factors.
