Question

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

Answer 1

Hint: The life cycle of this organism closely resembles that of most insects: a basic cycle that begins with an egg, then develops through a larva phase, a pupa phase, and eventually, into an adult. A bit like most insects they need an in-depth developmental pattern.

Complete answer: Polymorphism is the occurrence of two or more clearly different morphs or forms, also mentioned as alternative phenotypes; Taenia (flatworm) shows no polymorphism. Earthworms are hermaphrodites in nature, with each individual containing both male and female sexual organs. Pheretima or earthworm shows no sexual dimorphism, that means they don’t have clear distinctive features which can be used to identify males and females. The display of camouflage by the chamaeleon (a reptile) is often considered a visible mimicry. Complete metamorphosis has four stages, which includes the egg, larva, pupa and adult. Musca or the housefly exhibits these four stages. The larvae of houseflies also are called maggots. The house fly is a well-known cosmopolitan pest of both farms and homes. This species is always found in association with humans or the activities of humans. It is the most common species found on hog and poultry farms, horse stables and ranches.
So, the correct answer is option B.

Note: It is important to note that when a chameleon changes colour and camouflages in its surroundings so that its prey can't spot it easily. There are many animals which mimic their surroundings or other species within the vicinity. Some examples are butterflies, beetles, some fish, and a few amphibians.
