NEET BIOLOGY

Detailed explanation-1: -Beetles, butterflies, flies, and wasps are among the insects with four stages of metamorphosis. Some insects, such as grasshoppers and termites, have fewer stages. Metamorphosis also happens in animals other than insects. Most amphibians go through metamorphosis.

Detailed explanation-2: -For all organisms that go through metamorphosis (beetles, flies, ants, bees, and wasps as well as butterflies and frogs), their hormones begin the process and keep it going. Unlike butterflies and frogs, some insects go through only a three-stage process (egg, nymph or larva, and adult) called incomplete metamorphosis.

Detailed explanation-3: -Metamorphosis of the tadpole larva into an adult frog is one of the most striking transformations in all of biology (Figure 2.4). In amphibians, metamorphosis is initiated by hormones from the tadpole’s thyroid gland, and these changes prepare an aquatic organism for a terrestrial existence.

Detailed explanation-4: -Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.
