Patterns of repeated activity such as contraction and relaxation of the heart and inhaling followed by exhaling in breathing are common examples of circadian rhythms.

Question

Quizplus · Accepted Answer

Patterns of repeated activity such as contraction and relaxation of the heart and inhaling followed by exhaling are not examples of circadian rhythms, as they do not occur on a 24-hour cycle. They are instead examples of other biological rhythms, such as cardiac rhythms and respiratory rhythms. Circadian rhythms refer specifically to biological processes that occur on a 24-hour cycle, such as sleep-wake cycles and hormone production.
