Behaviors of physiological adaptations that allow a small desert mammal to survive severe drought conditions include all of the following except:
The absence of sweat glands
Inactivity during the day
The production of nearly dry feces
The use of water derived from the metabolism of food
The excretion of ammonia in substantial amounts

The excretion of ammonia in substantial amounts would definitely not help an animal to survive in the desert. In fact, any terrestrial (land dwelling) animal would want to avoid excreting ammonia. The proximal tubes of the kidneys re-absorb water by an intricate process of diffusion termed osmosis (definition of osmosis = transfer of a liquid solvent (H2O) through a semi-permeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to transfer of solvent; transfer of solute is called dialysis. In either case the direction of transfer is from the area of higher concentration of the material transferred to the area of lower concentration. This spontaneous ...
