the reason the hypodermis acts as a shock absorber is that ______.
the cells that make up the hypodermis secrete a protective mucus
it has no delicate nerve endings and can therefore absorb more shock
it is located just below the epidermis and protects the dermis from shock
the major part of its makeup is adipose, which serves as an effective shock absorber

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Hypodermis cells do not secrete protective mucus (mucus secretion is more associated with other structures like mucous membranes), so this is incorrect.
• Option 2: The presence or absence of nerve endings is not related to its shock - absorbing function. So this option is wrong.
• Option 3: The hypodermis is below the dermis (not just below the epidermis protecting the dermis), so this description of its location is incorrect.
• Option 4: The hypodermis (subcutaneous layer) is mainly composed of adipose (fat) tissue. Adipose tissue can effectively absorb shock and provide cushioning, which explains why the hypodermis acts as a shock absorber.

Answer:

D. the major part of its makeup is adipose, which serves as an effective shock absorber
