Question

what does it mean that the parents incubate the egg until it hatches? they keep the egg at a cold temperature. they roll the egg around to help the embryo grow. they keep the egg at a warm temperature. they keep the egg in a pouch.

Explanation:

Incubation in animals refers to maintaining eggs at a consistent warm temperature, which is required for the embryo inside to develop properly until it hatches. The other options are incorrect: cold temperatures would stop embryo development, rolling eggs is not the core definition of incubation, and keeping eggs in a pouch is a specific reproductive behavior (not the general meaning of incubation).

Answer:

C. They keep the egg at a warm temperature.
