A particular electrical signal being transmitted to a neuron is sufficient to generate an action potential. If the magnitude of the incoming electrical signal is doubled, the action potential will ________.
A) be twice as strong
B) last twice as long
C) undergo no changes in strength, speed, or duration
D) travel twice as fast down the axon
