Question

Which of the following statements is true?

O Cold blooded animals have cold blood.
Cold-blooded animals change their body temperature to match the environment.
Mammals and birds are usually cold blooded.
All of the above.

Answer 1

Endotherms, such as mammals and birds, are able to maintain a constant body temperature in the face of changing environmental conditions. In contrast, cold-blooded animals, or ectotherms, have a body temperature that matches their environment and varies with it.

Step-by-step explanation:

An animal that maintains a constant body temperature in the face of environmental changes is called an endotherm. These animals are able to maintain a level of activity that an ectothermic animal cannot because they generate internal heat that keeps their cellular processes operating optimally even when the environment is cold.

Mammals and birds evolved endothermy, meaning they regulate their body temperature from the inside through metabolic or physical changes. This allows them to maintain a relatively stable body temperature regardless of the outside temperature.

Cold-blooded animals, also known as ectotherms, rely on external temperatures to set their body temperature. Their body temperature varies with the environment.

Answer 2

Step-by-step explanation:

Cold blooded animal did not have cold blood.

Cold blooded animals can’t change their body temperature to match the environment.

Mammals and birds are not cold blooded.
