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 __________.
A) show no change
B) also show action potentials
C) show chemical but not electrical changes
D) none of the above; she cannot answer her question using this method

Quizplus · Accepted Answer

If the nerve communicates chemically, then the fluid from the first container containing the action potentials should also elicit action potentials in the second specimen. Therefore, choice B, also showing action potentials, is the best answer.
