Question

The stages in the metamorphosis of Musca domestica are in the order
A)Egg Larva, pupa, Imago
B)Egg, Nymph, Adult
C)Egg, Pupa, larvae, Adult
D)Egg, Larvae, Nymph, Adult

Answer 1

Hint: Musca domestica is the scientific name for the common housefly. The housefly undergoes metamorphosis to become an adult. The development in this class is indirect where the adult is altogether a new being as compared to the larvae.

Complete answer:
Metamorphosis is a cyclic process which an organism undergoes to change into an adult. It starts with the hatching of eggs. The metamorphosis is regulated by the thyroid hormone. Metamorphosis is mediated by the cell growth and division.

The housefly undergoes metamorphosis to convert into an adult. The lifecycle of the Musca domestica starts when the female lays an egg. Each female lays around 150 eggs. The eggs hatch into larvae in a single day. These larvae are known as maggots. The maggots undergo molding and changes into pupa. In a few couple of days, the pupa develops wings, limbs, and emerges as an adult.

Nymph- Nymph is an immature form of several invertebrates. They are sexually immature but are similar to the adults. Example grasshopper.
Imago- The last stage of the life cycle in the butterfly is called imago.

Hence, the correct answer is option (A)

Note: The females lay eggs in the moist and decaying environment. The eggs hatch into maggots very soon. It is the most common fly found at home and is a major cause of several diseases. They have the ability to adapt resistance to several different kinds of environment.
