Quizplus · Accepted Answer

Research has shown that hunger is not solely based on stomach contractions, as even individuals who have had their stomachs removed may experience hunger. In fact, hunger is a complex physiological and psychological process that involves various hormones and neurotransmitters. However, option A is incorrect as stomach contractions are a sign of hunger. Option C is also incorrect as rats whose stomachs are removed will still experience hunger and will eat if food is provided. Option D is partially correct, as ghrelin is a hormone that is released by the stomach when it is empty and stimulates hunger, but the question does not provide enough information to confirm whether less ghrelin is secreted when the stomach is empty.
