Question

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

Explanation:

Paracrine signaling involves signaling molecules (paracrine factors) that act on nearby cells. These cells are of a different type than the signaling cell. Autocrine signaling targets the same cell or cell - type (so the second option is for autocrine). Neurotransmitters are related to synaptic signaling (not paracrine). Endocrine signaling targets distant tissues (using hormones in the bloodstream).

Answer:

Nearby but different types of cells
