Answer 1

Cell signaling between nerve cells can be thought of as an example of paracrine signaling because a signaling molecule (neurotransmitter) is released and travels between the cells across synapses.

Step-by-step explanation:

Paracrine signaling is a type of local communication between cells that are close together (A) In the case of cell signaling between nerve cells, it can be considered an example of paracrine signaling because the signal is transferred across synapses, which are small distances between nerve cells. In this process, a signaling molecule called a neurotransmitter is released by the presynaptic cell and travels to the postsynaptic cell to transmit the signal.
