removing dissolved inorganic solids out of a solution (water). This type of system involves using many different filters and membranes in order to purify and improve the drinking quality of water. There are also ultraviolet systems which do a remarkable job at disinfecting water. Ultraviolet systems can destroy 99.99% of harmful microorganisms in the water very effectively and they do this by using a lamp or bulb which emits UV light which is then used as energy to attack the microorganism in the water

What exactly is the electromagnetic spectrum? Is a continuous range of wavelengths‚ which includes gamma rays‚ ultraviolet waves and other forms of electromagnetic radiation. How does the issue of scarcity and interference relate to the electromagnetic spectrum? The spectrum is considered scarce because of the limited number of frequencies for operation and two parties cannot broadcast on the same frequency in the spectrum. Interference not only can be caused by broadcasters but by natural phenomenons

with darker complexions. Melanoma occurs in people over a wide age bracket. Rates continue to increase with age‚ the highest being among people in their 80’s‚ and yet still one of the most common cancers in young adults. Etiology Exposure to ultraviolet radiation seems to play a large role in the development of this disease. Intermittent‚ intense sun exposure‚ especially as a child or teenager can put someone at high risk for developing melanoma. It has been shown that melanoma is more common

mainly in the circulatory and respiratory systems which are both very important and crucial to survive. Ozone layer depletion is a very serious decline of gas in the ozone layer which is bad because the less ozone we have surrounding us‚ the more ultraviolet rays can reach us. Those UV rays are harmful to us and cause skin cancer and the rates of that happening to people are increasing as the years go on and the ozone layer decreases. Smog is a major cause of air pollution and humans are the

• Depletion of ozone and formation of ozone hole • Ozone‚ in fact is a gas having fishy smell and O3 molecules which works as the protective shield for the life in the earth. It absorbs solar ultraviolet radiations and thereby protects life on the earth from several damage such as DNA mutation‚ skin cancer‚ blood cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly
