What does "molting" refer to in the context of insects?

In the context of insects, "molting" specifically refers to the process of shedding the outer exoskeleton periodically. Insects, being arthropods, possess an exoskeleton made of chitin, which provides structural support and protection. However, as insects grow, their rigid exoskeleton does not expand; therefore, they must molt to accommodate their increasing body size.

During the molting process, insects will cease feeding and prepare for the shedding of their exoskeleton. This involves growth of a new, larger exoskeleton beneath the old one. Once the old exoskeleton is shed, the new one is soft at first, allowing the insect to expand its body by taking in air or water before hardening. This process is crucial for their development and growth, allowing them to transition through various life stages, such as from larva to pupa to adult.

The other options provided pertain to different biological processes or characteristics. Transforming into a new species does not occur through molting; color change for camouflage is a behavior some insects may exhibit but is not related to molting; and while molting does allow for increased size, it does not specifically denote the act of increasing body size itself. Instead, molting is
