Tropical forests contain dense trees, which allow less sunlight to penetrate. emergent trees are trees that grow to a height of more than 45 to 55 meters, above the usual height of trees in tropical forests. which system provides the best possible explanation for why these trees grow to those heights?
growth pattern
homeostasis
nervous system coordination in plants
phototropism

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.  

option c is the correct answer.
