QUESTION 18 Match the description and examples provided with the categories in which they belong: AUn-programmed or B - Programmed. Aging process is largely determined by environment and behavior. The aging process is largely determined by genes and genetics. A. Programmed Says that normal aging follows a pre-determined plan. B. Unprogrammed Says that the aging process cannot be modified. Says that the aging process can be modified.

Answer 1

Ans) 18) Aging process is largely by environment and behavior- unprogrammed

The aging process is largely determined by genes and genetics- programmed

Says that normal aging follows a pre determined plans- programmed

She that aging process cannot be modified- programmed

Explaination:

- The programmed theories imply that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development. This regulation would depend on changes in gene expression that affect the systems responsible for maintenance, repair and defense responses.

- Unprogrammed theories, also known as non-adaptive or passive theories, contend that aging does not serve a valid "selectable" evolutionary purpose and that therefore an evolved mechanism whose primary purpose is to cause aging or otherwise purposely limit life span can not exist, at least not in mammals
