4. What will happen when you trigger an action potential at each end of a very long axon?
(A) Both action potentials will continue their transmissions to their respective distal ends.
(B) The action potential starts close to the soma will transmit to the other end.
(C) The action potential starts far away from the soma will transmit to the other end.
(D) Two action potentials will merge into one action potential that subsequently transmits to the axonterminal in a larger amplitude.
(E) Two action potentials will cancel each other around the middle of this axon.
