Question

What are goosebumps? What role do they play in our body? Why did they evolve in other animals? Be detailed in your response.

A. Goosebumps are tiny bumps on the skin caused by the contraction of arrector pili muscles. They play a role in temperature regulation and evolved in animals for thermoregulation.

B. Goosebumps are a skin condition caused by excessive cold. They have no specific role in the body and are a result of evolution.

C. Goosebumps are caused by skin irritation and have a protective function against external elements. They evolved in animals for defense mechanisms.

D. Goosebumps are an involuntary response of the body's nervous system. They play a role in responding to stress and evolved in animals for survival instincts.

Answer 1

Goosebumps are tiny bumps caused by muscle contraction and play a role in temperature regulation. They evolved for thermoregulation in animals.

Step-by-step explanation:

Goosebumps are tiny bumps on the skin caused by the contraction of arrector pili muscles. They play a role in temperature regulation and evolved in animals for thermoregulation. When the body is too cool, these muscles contract, moving hair follicles and lifting hair shafts, resulting in more air being trapped under the hairs to insulate the surface.
