Step-by-step explanation:
Hunger and appetite are two related but distinct concepts. Hunger is the physiological sensation that arises when our stomach is empty, and it is primarily regulated by factors such as stomach contractions, blood glucose levels, and chemical signals to the brain. On the other hand, appetite refers to the psychological desire or preference for specific foods. Appetite can be influenced by external factors such as advertising, smells, and social cues. While hunger is a physiological response, appetite is more subjective and can vary from person to person.
