Question

Which of the following animals undergo the process of metamorphosis?
A. Frogs
B. Insects
C. Mosquito
D. All of the above

Answer 1

The biological process by which an animal physically develops after birth or hatching, which involves a conspicuous and relatively abrupt change in the structure of the animal's body through the process of cell growth and differentiation is known as metamorphosis. Metamorphosis can be undergone in some insects, amphibians, fish, mollusks, crustaceans, echinoderms, cnidarians, and tunicates which is then often accompanied by nutrition source change or behavior.

Complete answer:
Option A. Frogs: A frog in its complete life, goes through five stages of life. In each stage of life, it changes and grows. Frog does undergo the process of metamorphosis. During the stage of a frog’s metamorphosis, an egg from the parent will hatch into a tadpole, which will then develop back legs at first, and then front legs. After that, it became a full-grown adult frog.
Hence option A is correct.
Option B. Insects: Most of insect life begins in the form of an egg. After the egg stage, the insect grows and undergoes a series of physical transformations until it reaches adulthood. This transformative phase is known as metamorphosis. Hence insects undergo metamorphosis.
So, option B is also correct.
Option C. Mosquito: Similar to insects, mosquitoes also grow through four phases of metamorphosis - egg, larva, pupa and adult.
Hence option C is also correct.
Option D. All of the above: Since options A, B and C are correct.
So, option D is the correct answer.

Hence, Option D. All of the above is the correct answer.

Note:
Other examples include starfishes and other echinoderms. They undergo metamorphosis that includes a change from bilateral symmetry of the larval stage to the radial symmetry in the adult stage. In crabs, lobsters, and other crustaceans and also in snails, clams, and other mollusks, metamorphosis patterns are well known. Larval form of the urochordate is a tadpole-like shape and is free swimming; but the adult is sessile and somewhat degenerate.
