Quizplus · Accepted Answer

The circadian rhythm refers to the 24-hour cycle of physiological and behavioral processes that regulate sleep, wakefulness, hormone production, and other bodily functions in humans. It is driven by an internal biological clock located in the hypothalamus of the brain. A is incorrect because it only refers to the sleep and wake phases, failing to capture the full scope of the biological clock. B is incorrect because it is not commonly used in scientific literature to describe the circadian rhythm. D is incorrect because the yo-yo theory does not exist as a recognized term in the field of circadian rhythm research.
