Natural resources are not required for all energy producing technology. select the best answer from the choices provided t f

The right answer is False.

The energy industries require a wide variety of natural resources: obviously coal, oil, gas, but also large quantities of water and rare metals. Water needs are particularly important. Apart from its role in the hydroelectric industry, it is used to cool the various thermal power plants, to facilitate the extraction of oil and gas, to produce the plants needed for biofuels.

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.
