a 7th grade student is creating a dichotomous key for their science class to identify the organisms shown, grass and mushrooms. which of the answer choices is the next logical questions for step 4 in making this dichotomous key?

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.
