Poison ivy is a weed that produces an oil which causes skin rashes. Scientists want to perform an experiment to see if poison ivy grows taller when exposed to more carbon dioxide.
How should the control group in this experiment be treated?

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.
