Another important constituent of air is carbon dioxide. As stated before, plants use it to synthesize carbohydrates, a basic food for all of us. It is also one of the green house gases that help to retain the warmth of the suns rays on earth, making weather conducive for life. You can pe..

It is the air-filled cavity inner to the ear drum, tympanum. It is separated from the inner ear by a partition with two membrane-bound apertures. The upper aperture is oval and is called fenestra ovalis (oval window). The lower one is round and called the fenestra rotunda (roun..

The nasal passage is lined by the nasal mucosa that have hairs and mucou-secreting cells. The hairs act like filters to remove the dust particles from the inhaled air. The mucous secreted by Bowman's gland keeps the inhaled air moist. The chemicals released by the various odorif..

Root - The root system is poorly developed as in Eichhornia or absent as in Ceratophyllum Stem - The stem may be reduced as in Le..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted over a certain period of time, and is not easily ..

Radioactive Waste - Waste products from nuclear power stations etc. are becoming a serious problem. They should be put where the radiation can do no harm. Unfortunately, there is no way of stopping a radioactive nucleus from emitting radiation. Nuclear energy has some advantages over foss..

Construction of sound proof rooms for noisy machines in industries. Use of horns with jarring sounds to be banned. Noise producing industries, aerodromes, and railway stations to be shifted away from the inhabited areas. Proper law should be enforced to check the misuse of loud..

Ozone (O 3 ) - Ozone is an allotropic form of oxygen. Its molecular formula is O 3 and molar mass is 48 g mol - 1 . Schonbein (1840) concluded that Van Marums observations in 1785 of a peculiar smell, when an electric discharge was passed through oxygen (or air), was in fact a new gas. He..
