Answer 13)
Discovery of Antibiotics opened a new horizon in the study and discovery of medicine. This is because Antibiotics help to cure Bacterial diseases. Antibiotics block the bio-chemical pathway utilized by the bacteria to develop the cell wall which protects the microbes from enemies. In this way by blocking the bio-chemical pathway, the bacteria gradually dies and the disease gets cured. For this reason the invention of Antibiotics hold a great significance in the development of medicine.
Answer 14)
Delhi is warmer than Mumbai, because not only the distance from equator determines the climate of a place, but the distance from coastal regions to determine the climate/ weather of a place.
As we know, Mumbai is closer to the western coast of India than Delhi, which does not fall under the region of coastal area. So Mumbai is closer to Western Coast of India than Delhi. For this reason Delhi is warmer than Mumbai.
