The scientist who proposed that organism evolved over time to adapt to their environment to survive

Charles Darwin

Explanation:

Charles Darwin developed the theory of Natural Selection after doing research on the Galapagos Islands. He said that organisms evolved over time as they adapted to their environment. This picture might help.

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.  

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
