Question 23 of 30 1 Point
Which of the following traits are characteristic of all mammals?
A. They breathe through gills.
B. They walk on two limbs.
C. They lay eggs that develop outside the mother's body
O D. The mother feeds her young with her own milk.

D

Explanation:

Humans are mammals, so let's analyze the answer choices using this information.

A. They breathe through gills

Humans don't breathe through gills, so this answer cannot be correct.

B. They walk on two limbs

Humans do walk on two limbs, but let's think of other mammals. Cats and dogs are mammals, but they walk on four, not two limbs. Therefore, this answer is not correct.

C. They lay eggs that develop outside the mother's body

Humans don't lay eggs, and neither do other mammals. This is not correct.

D. The mother feeds her young with her own milk.

Humans do feed their young using milk. Nursing their young through milk is a characteristic of all mammals.

The correct answer is D. The mother feeds her young with her own milk.
