Awoman is training to improve her running capabilities for an upcoming marathon. she is progressively increasing the distance and time of her runs. which principle best explains physiological adaptions occuring to the woman's aerobic energy system?

The correct answer would be metabolic specificity.

Metabolic specificity is one of the principles of the strength and conditioning of the body.

It deals with the energy demands of the body.

To develop endurance one must include long bouts of exercise with very less duration of rests in between the sets.

In contrast, one must take longer rest periods to develop maximal power and strength. Longer rest periods help in increasing the intensity of each bout.

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.
