Answer 1

1. This exercise is undertaken to remove grease dust. And dirt this process is called a scouring.
2. Take a strip of iron and put wax on it at regular interval points. Heat the other end of the iron strip. You will observe that as the end being heated becomes hotter, it gradually transfers heat to the other end. This is proven by the melting of the wax pieces placed at intervals.
3. The digestion process in Ruminants begins by chewing and swallowing its food. Ruminants do not completely chew the food they eat, but just consume or gulp as much they can and then swallow the food. ... This cud produced is regurgitated back into the animal's mouth where they can be chewed again.
4. Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
5. Step 1: Raising silkworms & harvesting cocoons. Step 2: Thread extraction Step 3: Dyeing. Step 4: Spinning. Step 5: Weaving.
6. The process of making fibre into wool follows shearing, scouring, sorting, cleaning of burrs, dyeing, straightening, combing and finally rolling into yarn.
