Salivation on seeing tasty food shows which complex coordination?
Answer and explanation
Correct answer: Coordination among a sense organ, the brain, and a gland
The governing concept is nervous coordination followed by glandular response. Seeing attractive food provides a visual stimulus detected by the eyes. Nerve impulses travel to the brain, where the information is processed; the brain then activates autonomic pathways to the salivary glands, causing secretion of saliva. Thus option A correctly identifies coordination among a sense organ, the brain, and an effector gland. The other options combine unrelated plant and animal structures or invent nonexistent connections.
