What generally occurs right before an insect molts?

  1. It hardens its exoskeleton

  2. It forms a new, soft exoskeleton

  3. It increases its body size

  4. It sheds its legs

The correct answer is: It forms a new, soft exoskeleton

Before an insect molts, it forms a new, soft exoskeleton beneath its existing hard shell. This process is vital for growth, as the insect is unable to increase its size significantly while its hardened exoskeleton remains intact. The newly formed soft exoskeleton allows for expansion once the old exoskeleton is shed. After the shedding occurs, the insect's new exoskeleton will harden over time. This sequence is crucial in the insect's development, allowing it to grow larger and transition through different life stages.
