Some tissues have only a few cells with the specific receptors needed for a signal response.How can the tissue respond most efficiently to that signal?
A) Increase release of neurotransmitter.
B) Allow the signal to diffuse between cells via gap junctions.
C) Allow the circulatory system to carry the signal to other cells.
D) Increase gene expression for the receptor.
E) Increase the number of signaling molecules.

Gap junctions allow for direct cytoplasmic connections between cells, enabling the signal received by cells with the specific receptors to be quickly and efficiently shared with neighboring cells that may not have those receptors. This facilitates a coordinated response across the tissue despite the limited number of cells initially receiving the signal.
