Fossil fuels, such as coal and oil, get their names because they form from fossilized organisms trapped under extreme pressure and heat from the center of Earth. Explain how the model shows the requirements for fossil fuel formation.

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.
