Water is not considered as nutrient, but plays a vital role in digestion. State its
importance role in life.

Answer 1

Answer:

Health care beauty: Medicines- pills, vaccine, diagnostic tests all involve chemistry. From the birth to death all has been possible by the service of chemistry.

All our cosmetics including beauty products involve chemistry (powder, creams, lotions, perfumes etc.)

2.Industries and transport: From cloth mills, lather factories, petro-chemical industries and refineries to metal industries- all use numerous fuels for power generation and chemicals for processing their product and improve their quality and simultaneously produce pollution. Due to pollution and over usage of burning fuels ozone depletion, global warming has paved way to destruction of planet earth. To avoid these bad effects again chemistry helps by introducing bio fuels.

3. Food security and agriculture: By the introduction of inorganic fertilizers green revolution started with increase in agricultural production. Usage of pesticides during farming, preserving grains from pests, rats mice from storage has helped a lot. Genetically modified seeds have helped in the product of crops which are efforts in bio-chemistry. At the same time preservatives in packed food products have side effects.

4. Science and technology: Development in science and technology has very high benefits but at the same time draw backs. Invention of Bombs, weapons of mass destruction all are also causes of destructive chemical reactions. But chemistry has given measures too in the form of safety suites and NBC resistant bunkers. Forensic science has helped in solving various crimes. Tele-communications, Information Technology and Space Missions- all bank on the chemistry of semi-conductors and nano-tubes.

Finally chemistry involves all the reactions involved in every object on the world and also outer space. Both good and bad are involved. It all depends on we the human beings to take it in constructive way rather than the destructive terms making world happy, cool and safe place to reside.
