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

the answer is c.) there is a warm front in region a and a stationary front in region b.

the correct answer in apex is tissue development, i know because i just had this question
