Circadian rhythms are a type of biological rhythm that occur on a roughly 24-hour cycle. While not all biological rhythms are circadian rhythms, many biological rhythms, such as sleep-wake cycles, hormone levels, and body temperature, are also on a 24-hour cycle and are therefore considered circadian rhythms. Choice A is incorrect because circadian rhythms are a type of biological rhythm. Choice C is incorrect because not all biological rhythms are circadian rhythms. Choice D is incorrect because there are many biological rhythms that occur on different cycles, such as menstrual cycles, which typically last around 28 days.
