Question

Complete metamorphosis is observed in
(a)Silverfish
(b)Gypsy moth
(c)Bed bug
(d)Grasshopper

Answer 1

Hint A biological process of physical development of an animal after birth for hatching which involves abrupt changes in the animal's body structure with the cell growth and differentiation is metamorphosis.

Complete answer:
Gypsy moth shows complete metamorphosis. The change in anatomy and physiological form of life stages which occurs in the animal and make up the process of complete metamorphosis. A Gypsy moth is a eukaryotic insect that was introduced in North America and is indigenous to Europe. It became an invasive species in 1869 and imported with the intent of interbreeding with the silkworms to develop a silkworm industry. It was considered a nuisance ten years ago and a major outbreak occurred in 1889 which recounts the extent of the devastation. It takes air for the small larvae of the Gypsy moth to be carried out by the wind. They hang on the spun silk threads and wait for the wind to blow. They constitute long hairs that increase their surface area and are suitable for carrying aloft. The Gypsy moth is affected by resource availability, sexual competition, and Predator density. They exist in low densities and enter the release phase when the outback faze rapidly expands and the population size rises several orders of magnitude and falls within only a few generations.

Additional information:
Silverfish: Silverfish is a wingless insect that derives its silvery light from the animal's grey color combined with the fish-like appearance of its movement. They have a nocturnal vision and are whitish when newly hatched and develop a grace hue and metallic shine when they get older.
Bed bug: Bed bugs are the insects that result in several health impacts such as skin rashes and allergy symptoms and usually feed on human blood at night. They bite and cause small areas of redness two prominent blisters and take a minute for a day to appear. They have five immature nymph life stages and mature sexually in their adult stage by shedding their skin through ecdysis at each stage and discarding their outer exoskeleton.
Grasshopper: It is an insect that is a living group of chewing herbivorous insects and is typically ground-dwelling insects. They escaped from the threads by leaping vigorously and do not undergo complete metamorphosis. They form from an egg into a nymph and become similar to the adult insect at each developmental stage.

So, the correct answer is 'Gypsy moth'.

Note: Gipsy moths are considered pests and feed on defoliated trees. Bedbugs are smart and can live anywhere and have a degree in anesthesiology. Grasshopper locust and have ears on their bellies. We cannot distinguish between very well and can hear.
