Biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.
<h3>What is the circadian rhythm?</h3>
The circadian rhythm refers to the biological process regulated by the duration of a calendar day, which is common for many organisms ranging from animals to plants.
