Unpaved shoulders are a characteristic of Rural driving environments

Explanation:

To understand this topic we first need to remember what unpaved shoulders are. Unpaved shoulders are the small lines between the road and the terrain. paved shoulders are the elevation frontier between the road and the pedestrian sidewalk. Its main objective is to prevent a car intrusion into the pedestrian road. Instead, because the unpaved shoulders are meant for rural environments they are not meant to prevent a car intrusion into the pedestrian territory. Because in those rural areas there are no pedestrians.

dang you just copied and pasted

explanation:

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.
