1) When the stimulus voltage was increased from 30-MV to 50 mv. what happened to the peak volume of the action potential.

It decreased proportionately that it also doubled.

It decreased to one half its peak valve

It increase slightly

There was no change.

2) Why did the neuron membrane potential goes from 70-mv-40 mv when you increase the extracellular control potassium.

Because the changed caused less potassium to leave the neuron

Because the changed caused less calcium to leave the neuron

Because the changed caused more sodium to enter the neuron

Because the change caused a lot more potassium to leave the neuron.
