The fossil record of insects has more gaps and larger gaps than the fossil record of vertebrates. From the following list, choose all the reasons why this is so: A. Insects were smaller than vertebrates.
B. Insect habitats were not in places where fossils formed.
C. Insects had fewer large, hard body parts that could fossilize the way vertebrates did.
D. Insects left less trace evidence that could fossilize than did vertebrates.
E. There were fewer insects than vertebrates throughout geological history.

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.
