Read the sections titled “retaining water” and “acquiring water.” explain how desert animals retain and acquire water in such a hot and dry environment? (site 3)

A desert is an area where there is very little amount of water available.Due scarcity of water it is very difficult for plants and animals to survive. Only those animals which need little amount of water can survive in the desert  

During the day, desert animals hide themselves in the bushes, whenever there is rain , the animals store water in their bodies. The loss of water from sweat and urine among these animals is minute. Most animals get water from the plants they eat or from the blood of their target/victim

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
