What did you include in your response? Check all that apply. The source of electromagnetic waves are charged particles that begin to oscillate when acted upon by a disturbance. Oscillating particles create an oscillating magnetic field. An oscillating magnetic field creates an oscillating electric field. An oscillating electric field creates an oscillating magnetic field.

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.
