Goose bumps
Correct Answer
D. Goose bumpsExplanation
The arrector pili muscles are responsible for causing goose bumps. These muscles are attached to hair follicles and contract when we experience certain emotions (such as fear or cold) or when we are touched. When these muscles contract, they pull on the hair follicles, causing them to stand up and creating the appearance of "goose bumps" on the skin. This physiological response is believed to have evolved as a way to make animals appear larger and more intimidating when faced with a threat.Rate this question:
