A brown mouse is mated with a white mouse. Brown fur is dominant to white fur. All of their offspring are brown. If two of these brown offspring are mated in the next generation, what fraction of their offspring will be white?

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

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.
