Question

The silkworm larva ceases to eat and starts spinning silk around its body
(a) At random
(b) From inside to outside
(c) From outside to inside
(d) All of the above

Answer 1

The hatchlings incubate out inside 10 to 11 days. It is clear as the gut disposes of the entirety of its green substance. The ecclesiastical stage is likewise called the resting or inert stage in the existing pattern of silkmoth.

Complete answer:
After the fourth and last shed of their skins, the silkworms will eat over a large portion of the food they will burn-through in the course of their lives. When they arrive at a basic size they will discharge their wholesome framework totally in anticipation of turning their casing around the body from outside to inside. The fifth instar eats for eight days, stops to eat, and begins turning silk around it from outside to inside. It finishes its life cycle in around 45 days.
Ova: Egg is the principal phase of a silkworm's life cycle. The four particular and sequential phases of the silkworm life cycle finish at one age and they include Egg, Larva, Pupa, and Imago. Advanced hatchlings are taken care of with developed and whole leaves. Prior to changing into an appropriate pupa, the developed hatchlings go through a pre-pupal stage during which disintegration (histolysis) of numerous larval organs like silk gland, shedding organ, stomach members occur. Our central goal is to give an online stage to assist understudies with examining everything without exception about Zoology. The existing pattern of the silkworm is as per the following: Egg: As we referenced over, the silkworm female can lay up to 500 eggs all at once in her short grown-up life. After generations, the male moth kicks the bucket. Its body is distinguishable into 3 sections, little head with extraordinary spinneret through which silk is radiated; chest with 3 portions, each with a couple of mauled genuine legs which are not utilized for strolling yet for holding the leaves while taking care of; and mid-region with 11 fragments.

So the correct answer is ‘from outside to inside’.

Note:
Numerous researchers have set significance on improving the monetary qualities of B. mori since its hatchlings, silkworms, are essential in the creation of silk. The previous is found in the external layer, while the last sort is normal in the center and inward layers of cover.
