Hi, you probably already submitted but I believe it will be A: All living things use energy to carry out essential life functions.

B. Not all living things have brains. For example, plants are living and they don't have brains. Neither do unicellular organisms.

C. Not all living things have stomachs. Plants eat, but not with a stomach. They absorb nutrients.

D. Phagocytosis is ingestion. Not all living things undergo it. Again, going back to the plants example, they do not, so therefore it isn't all living things.

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.
