Question

Quizplus · Accepted Answer

Our sleep-wake cycle follows a circadian rhythm, which is a 24-hour pattern that is influenced by biological and environmental cues. This rhythm is regulated by the suprachiasmatic nucleus in the hypothalamus, which responds to changes in light and dark signals to regulate our sleep pattern. The other options are incorrect as infradian rhythms are longer than 24 hours, ultradian rhythms are shorter than 24 hours, and diurnal rhythms refer to patterns of activity during the day.
