Cheetahs with longer legs are able to run faster than cheetahs with shorter legs. However, if a cheetah’s legs are too long, they are more prone to breaking. Which type of natural selection does this scenario represent?

answer; ///i believe the correct answer is (

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.
