Desert plants and animals are adapted to the lack of what and high

lack of water and high concentration of heat and dryness

Explanation:

Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

hope this helped:)

the endomembrane system i think

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
