Question

what would a physician say is the most likely reason for less body efficiency in aging adults? (1 point) an increase in lung and muscle capacity a decrease in nighttime insomnia an increase in natural supplement use a decrease in mitochondrial activity

Explanation:

To determine the most likely reason for less body efficiency in aging adults, we analyze each option:

• "An increase in lung and muscle capacity" is incorrect because aging typically leads to decreased lung and muscle capacity, not increased.
• "A decrease in nighttime insomnia" is incorrect. Insomnia (difficulty sleeping) often increases with age, and reduced insomnia would not cause less body efficiency.
• "An increase in natural supplement use" is incorrect. Supplement use does not directly cause reduced body efficiency; supplements are usually taken to address deficiencies, not cause inefficiency.
• "A decrease in mitochondrial activity" is correct. Mitochondria produce energy for cells. With aging, mitochondrial function declines, reducing energy production and overall body efficiency.

Answer:

D. a decrease in mitochondrial activity
