5. What is the response of an ectotherm, such as a lizard, when it encounters cold temperatures? It will move to a warmer spot.

It will run toward the stimulus.
It will become hungry.

It will move to a warmer spot.

Explanation:

An ectothermic animal, also known as a "cold-blooded" animal, is one that cannot regulate its body temperature, so its body temperature varies depending on the environment.

Many ectotherms live in environments that require little regulation, such as the ocean because the ambient temperature tends to stay the same.

because it is and it's just life man

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
