Answer:

Chitin is a structural polysaccharide made up of modified glucose chains. Insect exoskeletons, fungus cell walls, and some hard structures in invertebrates and fish all include chitin. Chitin is an important biopolymer found in nature. Fungi, arthropods, and nematodes are the principal producers. In insects, it acts as a scaffold, supporting the epidermis and trachea cuticles, as well as the peritrophic matrices that line the gut epithelium.

Snowcat [4.5K]

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.
