4. why might a loess be near a glacier? 5. what can happen to a dune over time? 6. which land-use practices contribute to wind erosion? 7. which farming practices can prevent wind erosion?

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.

its probably to later but whats the question
