I will mark brainest if you get it right Why are fossil fuels considered nonrenewable resources if they are still forming beneath the surface today?

A. They are being formed as a type of methane which we cannot use.
B. The fossil fuels are being broken down by a natural process.
C. We are depleting the fossil fuels much faster than they can form.
D. They are being formed too far beneath the surface.

first option is the correct answer

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.
