In which situation is the role of a gland as an effector clearer than that of a muscle?
Answer and explanation
Correct answer: Salivary gland secreting saliva on seeing food
The governing concept is that an effector may be a muscle or a gland. A salivary gland receives neural or chemical information and responds by secreting saliva, so option A clearly shows a gland acting as an effector. Options B and C involve skeletal muscles as effectors, while option D is a plant growth response involving hormones and unequal growth rather than a gland in the animal sense.
