Which is not an adaptation of desert animals that help them retain and acquire water in such a hot and dry environment?

Burrowing in moist soil, excreting uric acid, and getting water from food can all help desert animals conserve or obtain water. An internal cooling system may help an animal stay cool, but it does not directly help it retain or acquire water. Therefore, the choice that is not a water adaptation is “evolved an internal ‘air conditioning’ system to help them stay cool.”
