Exp. Quinine is a major drug used to treat malaria. Quinine is extracted from the bark of Cinchona tree.


Exp. Lycopene pigment, which is a red color carotene, is responsible for the redness of tomato.


Exp. The law of Inheritance was discovered by Gregor Johann Mendel. He is known as the father of genetics.


Exp. The acid produced by ants is called formic acid. Chemically it is a simple carboxylic acid.

Ans.5. (d)

Exp. Viticulture is the science, production, and study of grapes.


Exp. Cro-Magnon is a common name that has been used to describe the first early modern humans.  However, recent research suggests that the physical dimensions of so-called “Cro-magnon” are not sufficiently different from modern humans to warrant a separate designation.


Exp. Chillies are valued principally for their high pungency and colour. Pungency in chillies is due to the active constituent “Capsaicin” an alkaloid which is extracted from chillies and is used to the medicine. 


Exp. Chloroplast is considered as cell within a cell because it contains its own DNA. Hence, it is a semiautonomous organelle. It helps in photosynthesis.


Exp. Near-sightedness or myopia as it is medically termed is a vision condition in which close objects are seen clearly, but objects faraway appear blurred. It can be corrected by wearing concave or divergent lenses.


Exp. Encephalitis virus is the causing factor of Japanese encephalitis.
