Complete the sentence. Even in very hot temperatures, desert animals like camels and Arabian oryx regulate body temperature by very rarely blank. (A) Reproducing, (B) staying still, (C) moving, (D) breathing, (E) sweating.

This question is asking us about an adaptation of these two desert animals. An adaptation is a characteristic of an organism that makes it well suited to its environment and gives it a better chance of survival.

In hot temperatures, humans can regulate their body temperature by sweating. We can secrete sweat from special sweat glands in our skin. When we do this, a droplet of sweat can sit on the surface of the skin. This sweat droplet can absorb heat from our skin, which helps to lower the temperature of our body. The hotter it is, the more sweat we produce to cool us down.

Sweating is an adaptation that we’ve developed to deal with hot temperatures. However, the problem with sweating is that our body loses water in the process. For desert animals like camels and the Arabian oryx, they need to conserve water because water is very scarce in the desert. So these animals very rarely sweat and have other ways to regulate their temperature. For instance, camels have large humps, which store fat that can regulate body temperature. During the day, when it is very hot, this fat absorbs a lot of the heat from the body to cool the camel down. Then at night, when it gets cold, this heat can be released from the fat to warm the camel up. This way, the camel’s temperature stays within a certain range so it can be healthy.

Getting back to our question, in the statement “even in very hot temperatures, desert animals like camels and Arabian oryx regulate body temperature by very rarely blank,” the correct option to fill in the blank is given by answer choice (E), sweating.
