Explain how the scales of a bony fish can respond to changes in the food supply?

This is because fish grow according to variation in food in the waters. They grow faster in the summer than in winter, due to higher temperatures and increased food consumption. Patterns in the scales and otoliths reflect this change just like rings in the stem of a tree: summer zones are wide, and winter zones are narrow.

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.  

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
