Answer to Question 1

Ans:
A

Feedback:

Langerhans cells, the antigen-presenting cells of the epidermal skin, not only protect against harmful pathogens but also play an important role in the development of allergic skin conditions. Merkel cells play a role in the neuroendocrine cell function such as neurotransmission for autonomic nerves. Spherical melanosomes are found in people with light skin. Red hair has spherical melanosomes. Keratin is a protein that forms the surface of the skin and is also the structural protein of the hair and nails.

Answer to Question 2

Ans:
C

Feedback:

Osteopenia is characterized by a reduction in bone mass greater than expected for age, race, or sex that occurs because of a decrease in bone formation, inadequate bone mineralization, or excessive bone deossification. Increases in osteoblasts, inhibition of osteoclasts, and vitamin D supplementation would all be associated with high bone density.
