Question

What type of metamorphosis do roaches undergo_________

a) short
b) total
c) gradual
d) complete

Answer 1

Roaches undergo gradual or incomplete metamorphosis where immature roaches resemble wingless adult forms and grow progressively through molts.

Step-by-step explanation:

The type of metamorphosis that roaches undergo is gradual metamorphosis, also known as incomplete metamorphosis. Unlike insects that undergo complete metamorphosis (which includes stages of egg, larva, pupa, and adult, each looking different from the others), roaches develop from wingless immatures through successive molts that gradually increase in size and develop wing buds.

This growth occurs across juvenile stages until they become mature adults. Adults do not grow further after their final molt. Examples of insects that develop by incomplete metamorphosis, besides roaches, include grasshoppers and crickets, while ants, beetles, flies, and butterflies undergo complete metamorphosis.

Answer 2

Roaches undergo gradual or incomplete metamorphosis, where the young stages resemble the adults and develop through successive molts, with the correct option being (c) gradual.

Step-by-step explanation:

The type of metamorphosis that roaches undergo is gradual metamorphosis, which is also known as incomplete metamorphosis.

This process involves the young resembling wingless adults and gradually developing larger wing buds during consecutive molts, eventually resulting in functional wings and sex organs in the last molt. Unlike complete metamorphosis, which includes distinct life cycle stages of egg, larva, pupa, and adult, in gradual metamorphosis, each stage looks more similar to the adult than in the complete metamorphosis process.

Therefore, the correct option is (c) gradual, and I have mentioned the correct option in the final answer.
