Henry touched a hot plate and immediately moved his finger away from it. which best explains the integumentary system’s role in this reaction? a. oil in the skin sensed the temperature difference. b. nerve endings in the skin responded to the heat. c. some hairs stood up when the fingers touched the plate. d. his nails absorbed heat and moved his finger away from the plate.

B. Nerve endings in the skin responded to the heat.

Explanation:

The integumentary system of the body comprise of the skin and other appendages that protects the body from  damage such as injury and water loss. This systems includes hair, scales, hooves and nails. The nerve endings are the part of the skin which can sense the heat and directs the impulses to the brain to coordinate in muscular movement which allows the finger to move away from the hot plate.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
