Question

which type of junction permits the free diffusion of ions and small molecules between two cells? tight junctions anchoring junctions gap junctions voltage - regulated junctions i dont know yet

Explanation:

Tight junctions prevent diffusion. Anchoring junctions attach cells. Gap junctions have channels for ion/small molecule diffusion. Voltage - regulated junctions aren't for this diffusion. So gap junctions are correct.

Answer:

C. Gap junctions
