Question

question 13
exercise in later adulthood appears to minimize the detrimental effects of stress on the
a length of telomeres
b feelings of learned helplessness
c lack of perceived control
d hippocampus and memory

Explanation:

Telomeres are protective caps at the ends of chromosomes. Stress can shorten telomeres, and exercise in later adulthood has been shown to minimize this detrimental effect. Learned helplessness (B) is a psychological state where an organism believes it has no control over negative outcomes. A lack of perceived control (C) is related to psychological perceptions of one's ability to influence events. While the hippocampus (D) is involved in memory and can be affected by stress, the most directly relevant option based on biological aging and stress mechanisms is telomere length.

Answer:

A. length of telomeres
