Describe how a plant survives the change of seasons in a temperate deciduous forest. Write a short paragraph to explain your answer.

Which environmental factor would likely lead to an increase in genetic variation in a population of squirrels?

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.
