In the nephron depicted above, what will happen if part b malfunctions so that substances can no longer diffuse in and out? (2 points) water will not be reabsorbed through the collecting ducts adh will not be released into the bloodstream fluid from the blood will not enter the nephron useful substances will not be reabsorbed from the urine

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.
