beginning Vitamin D synthesis
to rid the body of solid wastes
a) 1, 2, 4
b) 3, 5, 6
c) 2, 4, 5
d) 1, 3, 6

Answer 1

The skin's functions include aiding in temperature regulation, forming a protective barrier against microorganisms, preventing dehydration, and synthesizing Vitamin D; hence, the answer is c) 2, 4, 5.

Step-by-step explanation:

The functions of the skin are numerous and vital for maintaining homeostasis within the body. These functions include: aiding in temperature regulation through thermal insulation and sweat production; acting as a protective barrier to microorganisms, which prevents infections; preventing dehydration by controlling water loss; and synthesizing Vitamin D when exposed to UV light, which is essential for bone health and other physiological processes. Notably, the skin is not involved in ridding the body of solid wastes, as excretion of solid waste is primarily the function of the digestive system.

Based on this information, the correct functions of the skin mentioned in the question are: aiding in temperature regulation, forming a protective barrier against microorganisms, and preventing dehydration (water loss), as well as beginning Vitamin D synthesis. Thus, the correct answer is c) 2, 4, 5.
