Which one of the following is a matching pair of an animal and a certain phenomenon it exhibits?

  1. Pheretima – Sexual dimorphism
  2. Musca – Complete metamorphosis
  3. Chameleon – Mimicry
  4. Taenia – Polymorphism

Answer

(2) Musca – Complete metamorphosis

Solution

Musca (housefly) passes through egg → larva (maggot) → pupa → adult, i.e. complete metamorphosis (holometabolous development).

∵ Pheretima is hermaphrodite, so it shows no sexual dimorphism.

∵ Chameleon changes colour to match the surroundings (camouflage), not mimicry.

∵ Polymorphism is shown by colonial forms such as Obelia, not by Taenia.

∴ Musca – Complete metamorphosis is the matching pair.
