The process of replication is the same for all living things because?

a)the structure of the dna is the same for all living things
b)the dna base pairs can pair up any way they choose
c)all living things have the same number of chromosomes
d)development is the same for all living things

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.
