Question

which of the following bodily functions is not affected by metabolism?
a. breathing
b. hair growth
c. digestion
d. circulation

Explanation:

Metabolism involves chemical processes that sustain life, affecting functions like breathing (gas exchange/energy), digestion (nutrient breakdown), and circulation (nutrient/oxygen transport). Hair growth is a slower, less direct metabolic - driven function compared to the others, and among the options, it's the one least affected by basic metabolic processes that drive essential life - sustaining functions like the other three.

Answer:

B. Hair growth
