Write and draw the various stages of the life history of silkmoth |
|
Answer» The LIFE cycle of silk moth starts when a female silk moth lays eggs. The caterpillar or larvae are hatched from the eggs of the silk moth. The silkworms feed on MULBERRY leaves and give rise to pupa. In the pupa stage, a weave is netted around by the silkworm to hold itself. After that it swings its head, spinning a fiber made of a protein and becomes a silk fiber. Several caterpillars form a protective layer around pupa and this covering is KNOWN as the cocoon. The silk thread (yarn) is obtained from the silk moth’s cocoon. The life cycle of the silkworm is explained below in detail.Life Cycle of SilkwormStage 1: EggAn egg is the first stage of the life cycle of the silkworm. The egg is laid by a female moth which is mostly the size of small dots. A female moth lays more than 350 eggs at a time.in the springtime, the eggs hatch due to the warmth in the air. This procedure happens once in every year.Stage 2: SilkwormA hairy silkworm arises after the eggs crack. In this stage of silkworms, the growth happens. they feed on mulberry leaves and consume a large amount of these leaves for around 30 days before going to the next stage.Stage 3: CocoonIn this stage, silkworms spin a protective cocoon around itself. It is the size of a small COTTON ball and is made of a single thread of silk.Stage 4: PupaThe pupa stage is a motionless stage. In this stage, people kill the pupa by plunging the cocoon into boiling water and UNWIND the silk thread.Stage 5: MothIn this stage, the pupa changes into an adult moth. The female moth lays eggs after mating and thus the life cycle of silkworm begins again.Processing of silk Extracting silk from the cocoon is known as the processing of silk. Silk is separated from the cocoon by exposing it to sunlight. After that reeling of silk is done, the process of unwinding silk from a cocoon. Silk thread is then bleached. Silk fiber is then spun into silk threads.*source byju's |

Ques-6 Whatismeteorite body |
| Answer» EXPLANATION:A meteorite is a solid PIECE of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to REACH the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then BECOMES a meteor and forms a fireball, also known as a shooting star or falling star; astronomers call the brightest examples "bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary GREATLY in size. For geologists, a bolide is a meteorite large enough to create an impact crater. | |

What are the 3 examples of Liquid changes into gas. |
| Answer» TION:PLZ MARK me BRAINLIEST | |
| 15481. |
You will answer some questions calculating Gravitational Potential Energy. The formula is Gravitational Potential Energy = Mass X Gravity X Height. By gravity they mean the acceleration of gravity. That's how fast something speeds up as it falls. It is 9.8 meters per second. So for these problems you always use 9.8 for gravity. For mass always use kilos. So if something is 500 grams you'll multiply .5 become 500 grams is .5 kilos. That should be review (converting between units). For height always use meters. So if something is 90 centimeters height you multiply. 0.9 because 90 centimeters is .9 meters. So if I have a ball that's 9 kilos at a height of 5 meters to find Gravitational Potential Energy (GPE) I multiply Mass (9) by Gravity (9.8) by height (5). So the GPE is 441 Joules. (GPE is measured in Joules) Another example. A ball of 600 grams is at a height of 70 centimeters, what is the GPE. It's Mass (.6) times height (.7) times gravity (9.8). (((It doesn't matter which order you multiply))) So the GPE is 4.116 Joules. The formula looks fancy GPE=mgh But it's just Mass times 9.8 times Height. Calculate GPE for these 4 scenarios. 1. An 80 kilo brick at a height of 80 meters. 2. An 8 kilo brick at a height of 8 meters. 3. A 700 gram ball at a height of 8 meters. 4. A 700 gram ball at a height of 80 centimeters. Had no idea how to do this.. Help please |
