Question

a woman aged 73 will have
○ a. about 5 percent of her total body hair follicles on her head
○ b. a decreased density of hair follicles
○ c. more than 6 million total hair follicles
○ d. increased body hair

Explanation:

As people age, hair - follicle density decreases. A 73 - year - old woman would experience a reduction in the density of hair follicles on her scalp. Option a is incorrect as there is no such specific proportion of head hair follicles to total body hair follicles related to age. Option c is wrong because the total number of hair follicles decreases with age and is not likely to be more than 6 million in an elderly person. Option d is incorrect as body hair generally does not increase in elderly women.

Answer:

B. a decreased density of hair follicles
