What does it really mean when we say that a neuron has a resting potential of -70 mV?
 
  a. The difference between the electrical environment of the interior of the cell and the exterior of the cell is 70 mV, with the interior being more negative than the exterior.
  b. The difference between the electrical environment of the interior of the cell and the exterior of the cell is 70 mV, with the exterior being more negative than the interior.
 c. The interior of the cell has a charge of -70 mV, whereas the exterior of the cell has a charge of +70 mV, for a total difference of 140 mV.
 d. The interior of the cell has a charge of -35 mV, whereas the exterior of the cell has a charge of +35 mV, for a total difference of 70 mV.
