a. mutation

Explanation:

A mutation is a change or alteration and a process that occurs in the DNA sequence of the organism. This happens due to the mistake in the DNA replication process or because of the environmental factors for example exposure to the UV radiation or due to smoking. These mutations either favors the survival of the organisms or they are lethal for the organisms.

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
