is the property of skeletal muscle whereby an increase in the frequency of action potentials enhances the force developed by the muscle cell?

Options are not provided in the question. Th equestion is as follows:

the property of skeletal muscle whereby an increase in the frequency of action potentials enhances the force developed by the muscle cell?

a. length-tension relationship

b. force-velocity relationship

c. internal tension

d. external tension

e. summation

e. summation

Explanation:

Summation is the property of skeletal muscle which occurs through  continuous addition of signals or stimuli together that produces a stronger contraction in the muscles.

If the motor neurons are increased, it results increment in action potential and hence increases the amount of active motor units in a muscle, which is called recruitment.

Hence, the correct option is e. summation

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.
