Quizplus · Accepted Answer

A circadian rhythm is a 24-hour internal clock that regulates many physiological processes, such as sleep-wake cycles, hormone production, and body temperature.

A biological clock refers to the molecular mechanisms that underlie circadian rhythms, while photoperiod refers to the duration of light exposure that an organism receives during a day.
