Final answer:
An insect with incomplete metamorphosis means that each stage of the insect's life cycle looks similar to each other and the immature form increases in size with each molt. The insect gradually develops larger wing buds during successive molts until it finally produces functional wings and sex organs during the last molt.
Step-by-step explanation:
An insect with incomplete metamorphosis means that each stage of the insect's life cycle, including the egg, larva, pupa, and adult, looks similar to each other. The immature form of the insect is called larvae and it remains similar in form but increases in size with each molt. The insect gradually develops larger wing buds during successive molts until it finally produces functional wings and sex organs during the last molt.
