A researcher wants to determine whether a particular nerve specimen communicates via electrical or chemical activity. She places two specimens of the nerves into two containers filled with fluid. She electrically stimulates the first sample and elicits action potentials. She then takes fluid from that container and drips it into the other container containing the second specimen. If the nerve communicates chemically, this specimen should __________.
