Answer;

-Endosperm

Explanation;

-In plants that undergo double fertilization, the structure that forms to nourish the seed is called the endosperm.

-Double fertilization occurs when one sperm cell fuses with the egg to produce a diploid zygote, and the other sperm cell fuses with the two polar nuclei to make  a triploid cell that develops into the endosperm.

- Endosperm is a  tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants).

A

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.
