In hydra, new organisms can. be produced from groups of cells that enlarge and stay attached to the parent for a time before breaking off and becoming independent .the method of reproduction is an example of ?

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.
