Step-by-step explanation:
Dr. Bush's research would show that hormones and neurotransmitters play distinct roles in behavior.
Hormones are chemical messengers that are secreted into the bloodstream and travel throughout the body, affecting any cells that contain receptors for them. They have widespread effects and tend to be slower to take effect, but the effects are longer lasting. On the other hand, neurotransmitters are released at synapses and their effects are localized and faster-acting compared to hormones.
