Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
Eukartyotic cells are found as bacteria or archaea. They are usually unicellular organisms. Has no nucleus. Has a very small cell size.
Prokaryotic cells are found in plants and animals. They are multicellular. Has a nucleus. And has a much bigger cell size.
They can have many of the same organelles, but prokaryotic cells are usually more advanced. They are both forms of life. They are both cells.
