Which one of the following is a matching pair of an animal and a certain phenomenon it exhibits? (a) Pheretima – Sexual dimorphism (b) Musca – Complete metamorphosis (c) Chameleon – Mimicry (d) Taenia – Polymorphism
Option B.In Musca, development is indirect with complete metamorphosis (holometaboly) including four stages as follows egg, larva, pupa and adult. In complete metamorphosis, larva after hatching, moults several times to become a fully grown one. It later becomes a pupa within a secreted case, called the puparium. Pupa differentiates into the young adult that breaks the puparium open and emerges outside. Then it grows to a mature form.
