Passage IV
Certain odorants (airborne chemical compounds) can stimulate a change in the electrical activity of the olfactory neurons in the antennae of the moth Manduca sexta. The change in the electrical activity of an antenna in the presence of an odorant can be detected as an increase in the antenna’s voltage relative to its voltage in the absence of odorants. The figure below shows the average change in antennal voltage for adult female M. sexta that were exposed to each of 5 odorants at each of 4 concentrations.
26. According to the passage, certain chemical compounds can stimulate a change in the electrical activity of a specific type of neuron in M. sexta. This type of neuron is found in what organ of the human body?
Your Answer is
Correct Answer is J
