Question

what do paracrine cells target?
nearby but different types of cells
distant tissues
the same cell or cell type
cells using neurotransmitters

Explanation:

Paracrine signaling involves cells that secrete signaling molecules (paracrines) which act on nearby cells, typically of different types (not the same cell/cell type, not distant tissues, and not related to neurotransmitter - based cell targeting). So the correct option is the one about nearby but different types of cells.

Answer:

A. Nearby but different types of cells
