Explanation:

Animal Fibre - Silk (it is obtained from the silkworm).

Paper - non lustrous material (because paper does not have its own light, so it is called non lustrous. Lustrous is used for things that has its own light for example - moon, and non lustrous means thing which doesn't has its own light).

Threshing - it's a process to separate grains from the stalk.

Weaving - weaving of cloth (for example sweaters and other cloths that can be made by weaving).

Solubility - the extent to which a substance gets dissolved in liquid ( for example, when sugar gets dissolved in water completely that is called Solubility)

Breathing - the process of inhaling and exhaling air (what we do with are nose, we breathe in and out)

Cell - structural unit of living thing (both plants and animals have cells, an organism is made up of cells)

Human made change - converting yarn into cloth (this can be done by humans, they change a yarn or thread into a cloth).
