Ion concentration differences produce an action potential creating a signal.The difference between a weak signal and an intense signal is
A)the action potential is graduated and a weak signal causes a small change in polarity.
B)weak stimuli only open sodium gates,strong signal also open potassium gates.
C)the frequency at which an axon fires.
D)a strong signal does not allow repolarization but sends a constant flow of ions.
