Mouth watering on seeing tasty food is an example of which type of control?
Answer and explanation
Correct answer: Response linked with nervous control
Seeing tasty food provides a visual stimulus. Receptors in the eyes send nerve impulses to the brain, and the brain coordinates a response through autonomic nerves that stimulate the salivary glands. The resulting secretion of saliva is therefore a nervous-control response, even though it is involuntary. Blood sugar regulation depends mainly on hormones such as insulin, while plant-hormone control and root growth are unrelated. Hence option B is correct.
