What is another name for the sugars organisms use for energy?

It is referred to as Glucose.

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.

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.
