What is the term for shedding the old exoskeleton in insects?

Melt
Molt
Release
Discard

The correct answer is: Molt

The correct term for the process of shedding the old exoskeleton in insects is "molt." This biological process, also known as molting or ecdysis, allows insects to grow and develop. During molting, an insect breaks free from its exoskeleton, which is rigid and doesn't expand as the insect grows. This is crucial for their growth, as it enables them to replace their old exoskeleton with a larger one. The term "melt" is not applicable in this context as it typically refers to the process of a solid turning into a liquid due to heat, which does not relate to insect biology. "Release" and "discard" do not accurately describe the specific process of shedding an exoskeleton; rather, they imply a more passive action without the biological significance of molting. Thus, "molt" is the appropriate and specific term used in entomology to describe this crucial developmental phase in insects.
