How can energy from the motion of the crank on a hand-powerd flashlight produce heat?

When you manually crank the flashlight, a coil of wire inside the generator converts the mechanical energy into electrical energy. This allows an electrical current to flow through the flashlight, thus lighting the bulb of the flashlight.

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..
