According to the all-or-nothing principle, what would happen if a cell were depolarized twice the normal amount needed to produce an action potential?
A) The strength of the action potential would be proportionate to the depolarization.
B) The intensity of the action potential would not be affected.
C) Nothing would happen because the cell must be polarized to fire.
D) The action potential would have an inhibitory effect on the next neuron.

The all-or-nothing principle states that a neuron will either fire or not fire an action potential depending on whether the threshold potential is reached or not. If the threshold potential is exceeded, the intensity or strength of the action potential will not be affected by the degree of depolarization beyond the threshold. Therefore, the intensity of the action potential would not be affected if the cell were depolarized twice the normal amount needed to produce an action potential.
