Question

In cockroach, metamorphosis requires
A. Three weeks
B. 40 – 70 days
C. 10 – 30 days
D. 5 – 13 days

Answer 1

Hint: Metamorphosis; a striking transition in the structure or shape of an individual after hatching or birth. Changes progressing to metamorphosis are activated by hormone secretion. In a cockroach, the metamorphosis requires more than a month's time.

Complete answer: Cockroaches evolve by gradual metamorphosis. Although all cockroaches mature by finishing a life-cycle composed of three different phases: eggs, nymphs and adults. The time it would take for a cockroach to progress from egg to adult would range from one cockroach type to another; from a little almost one month, approximately (40 – 70 days). A female cockroach produces eggs inside a capsule labelled as ootheca. Cockroach ootheca is unique for each cockroach population and can even be used for identification of species. The number of eggs which each ootheca carries depends on the characteristics of the cockroach. If the formation within the egg is complete, the nymphs will function together to escape out from the ootheca. Baby cockroaches would go through several phases, moulting (depleting their skin) and becoming bigger and bigger until they begin looking like mature cockroaches, but they are not fully adult and thus don't have highly formed wings. If wings are established in the species, cockroach nymphs could produce wing pads in subsequent stages. Once the cockroach reaches adulthood, the wings and antennae would be completely developed. It will also be capable of reproducing and multiplying.
So, the correct answer is option B.

Additional information: A cockroach can live around a year in warm and humid environments with adequate food and moisture. There also are a few variables that impact the life expectancy of the cockroach, such as mating species of cockroach will have its own predicted life expectancy.

Note: Cockroaches are nocturnal species that specify that they disappear during the day and are active at night. Comprehending the stage or life cycle of a cockroach might give us a better idea of the number of generations in one’s home. Since these creatures are really resilient and could go weeks to months without food, they can survive within or around their habitats for a prolonged period of time.
