Adaptation : An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment .
Humidity : Humidity is the amount of water vapour in the air. If there is a lot of water vapour in the air, the humidity will be high. The higher the humidity, the wetter it feels outside.
Shearing : Shearing refers to the occurrence of a shear strain, which is a deformation of a material substance in which parallel internal surfaces slide past one another.
Chlorophyll : Chlorophyll is a green pigment present in green plants which helps them to carry out photosynthesis . Chlorophyll is found in virtually all photosynthetic organisms, including green plants, cyanobacteria, and algae.
Neutralization : A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
Sericulture : Sericulture can be referred to the production of silk and the rearing of silkworms for this purpose.
