Difference between mitosis and mitotic cell division

Mitosis is the process of producing two identical daughter cells from a parent cell. When someone is trying to explain mitosis without using the words mitosis, they'll say through mitotic division. They essentially mean the same thing, just used in different contexts.

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.
