A) an increase in collagen and elastic fibres a
B) decrease in activity of sebaceous glands
C) a thickening of the skin
D) an increase in toenail growth
Correct Answer: B
Solution :
Due to ageing the skin becomes thinner. This is because the underlying fat, so abundant at infancy, is slowly lost. The skins connective tissue, called collagen and elastin, undergoes changes, causing the skin to lose firmness and become dry. The sweat and oil-secreting (sebaceous) glands in the skin also decrease, which makes it harder for the skin to hold moisture.
