Question

Quizplus · Accepted Answer

The natural circadian rhythm cycle is slightly longer than 24 hours, typically between 24 and 25 hours. Without external cues to reset this cycle, such as exposure to sunlight or darkness at regular intervals, the cycle would gradually shift to a longer duration, eventually reaching a cycle of 25 hours or longer. Therefore, choice B (24- to 25-hour) is the best answer.
