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.
The circadian rhythms enable the maintenance of homeostatic control of physiological functions and thus perform metabolic activities.
In conclusion, 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.
