Question

which is an adaptation?
a. a dog learns to roll over.
b. a cat learns to eat from a bowl.
c. a horse breaks its leg while running.
d. a camel has humps that store fat.

Explanation:

Adaptation refers to a trait that helps an organism survive in its environment. Camels' humps storing fat is an inherited trait (not learned like options A and B) that helps them survive in arid environments (unlike option C which is an injury, not an adaptation).

Answer:

D. A camel has humps that store fat.
