How does the process of cellular respiration connect autrotrophs
to heterotrophs?

process by which cells obtain energy from glucose. During respiration, cells break down simple food molecules such as sugar and release the energy they contain. Heterotrophs consume autotrophs in order to obtain energy. autotrophs produce the reactants needed by heterotrophs for cellular respiration.

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.
