Agroup of ponies lives in the chincoteague national wildlife reserve in virginia. the development of longer legs over time would be selected for if -
f it made the long-legged ponies run more slowly
g it decreased the rate of reproduction of the long-legged ponies
h it increased the survival rate of the long-legged ponies
j it prohibited the long-legged ponies from using available food sources

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
