Question

Quizplus · Accepted Answer

Circadian rhythms are internally generated cycles that govern physiological processes and behavior in many organisms, including humans. They are regulated by an internal "biological clock" that runs on a roughly 24-hour cycle, but can be influenced by external cues such as light and temperature. Circadian rhythms are not artificial inventions of timekeepers, nor do they occur on a monthly schedule or remain the same regardless of day-night changes.
