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 ...

Describe an Arizona ecosystem. List its contribution to your community and how humans have impacted the ecosystem
1. Identify a natural ecosystem in Arizona which you live or one near to
where you live? How does this ecosystem support you? What are some human
impacts on the natural cycling process of ecosystems in your community?
2. Because ecosystems change and may recover naturally from disturbance over
time, what factors affect decisions about whether human intervention is needed
to help ecosystem recovery? Provide examples
