Help i’m confused ???

anaphase for the first one be cause the chromosomes are being pulled away by centrioles.

metaphase for the second one because the chromosomes are in the middle and centrioles are attached to them, getting ready for anaphase.

telophase for the third one since the cells are separating.

prophase for the last one.

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.
