A reflex is a natural movement brought on by a particular stimulus.
<h3>What is stimulus?</h3>
A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor. The first element of a homeostatic control system is frequently an internal stimulus.

Answer: growth
Explanation: The growth stage of a product's life cycle is marked by increase in demand and hence rise in revenue generated by such product. At this stage of product life cycle, the product seems to have gained or won the heart of consumers. The growth stage is usually experienced after extensive market research and launch of a product. Once it gains the attention or popularity among consumers, revenue increases and the need to raise expenditure for promotional purposes arises so as to gain firm attention and shrug off competition from similar products.
