One disadvantage to a nerve net is that it can conduct impulses in two directions from the point of the stimulus. Most of the synapses in vertebrates conduct information in only one direction
A)as a result of the nodes of Ranvier.
B)as a result of voltage-gated sodium channels found only in the vertebrate system.
C)because vertebrate nerve cells have dendrites.
D)because only the postsynaptic cells can bind and respond to neurotransmitters.
E)because the sodium-potassium pump moves ions in one direction.
