Kiera is performing an experiment. she completed her first experimental trial and recorded the result. when she repeated the trial, she got a completely different result. what should kiera do? average the two results together and stop the experiment. change the second result to match the first result. quit the experiment immediately. look for possible sources of error, then continue with the trials.

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.
