ans 1 D

The axon of neurons signal target cells using membrane bound signalling molecules that act on receptors on target cells. Axon contacts with the other cells and neurons at junctions called as synapse. AT synapse the membrane of neuron contacts with the other cell, and transmit information in the form of chemical and electrical signals.
