If the amount of chemical messenger at a synapse becomes very low, what will happen to the nerve message?
Answer and explanation
Correct answer: Transfer of the message to the next neuron may become weak
A synapse is the junction or narrow gap between two neurons. When an impulse reaches the end of one neuron, chemical messenger molecules help carry the signal across this gap to the next neuron. If their amount becomes very low, the next neuron may receive insufficient stimulation, so message transmission becomes weak or may fail. Option A follows this mechanism; the other choices describe impossible or unrelated changes.
