Question

The order of metamorphosis in housefly is:
A. Egg, nymph, pupa, and adult
B. Egg, larva, nymph, and adult
C. Egg, larva, pupa, and adult
D. Egg, pupa, larva, and adult

Answer 1

Hint: Metamorphosis is a cyclical biological process by which an animal physically develops into its adult form. Houseflies larva is known as a maggot. The life cycle of a housefly begins when it is in its egg stage.

Complete answer: A female housefly is capable of laying up to 150 eggs in a batch. These eggs hatch into larvae within a day. These larvae are also known as maggots. These maggots moult several times in a day. They then choose a dark place to pupate. The fly pupae are similar to butterfly cocoons. Over a course of three-six days, the pupae develop their legs and wings. It ultimately emerges as full-grown house flies or an adult. Metamorphosis is a cyclical biological process through which an animal physically develops into its mature form. It starts soon after birth or hatching. It involves a conspicuous and relatively abrupt change in the animal's physical and anatomical body structure. This is done through cell growth and differentiation. House flies typically lay their eggs on animal faeces and garbage. They hatch to form white, legless maggots (larval stage). They grow to about ½ inch. When fully grown, maggots crawl away from their food source to undergo the pupal stage of metamorphosis. Complete metamorphosis and incomplete metamorphosis are the two types of metamorphosis. They are two growth types where the physical body form of insects changes during their lifecycle.
Hence, the correct answer is option C.

Note: Frogs have multiple stages in their life cycle. They undergo metamorphosis. The following are the steps:
i. Egg stage: Frogs lay eggs that are not covered by a calcareous covering, rather by a gelatinous sheath.
ii. Tadpole stage: Tadpoles are the next stage. They hatch from the egg with poorly developed gills, mouth, and tail.
iii. Tadpoles develop primordial legs.
iv. Froglet stage.
v. The mature frog that lost its tail.
