Is your prediction supported by the membrane potential chart? Explain your answer.

The membrane potential of a resting neuron is primarily determined by the movement of K + start text, K, end text, start superscript, plus, end superscript ions across the membrane.Zero voltage across the membrane, as measured by a voltmeter with one electrode inside and one electrode outside the cell.

Hope this answer correct :)

Yes, it is. The chart shows that the initial charge of the neuron is negative. When the neuron is stimulated, sodium ions enter the cell. So, the voltage inside the cell changes to positive. When potassium ions move outward, the voltage decreases until it reaches its previous state.
