Which would most likely cause the liquid in Tube A to rise? A Water and starch volumes being the same.
B Starch concentrations being equal on each side of the membrane.
C Water passing from a region of lower starch concentration to one of higher starch concentration.
DSolute in the tubes changing from a higher temperature to a lower temperature.

d solute in the tubes changing

Explanation:

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.
