... power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the b ...

... morphine or heroin. The folks that say they don't want to quit, because of the pleasure they derive from smoking, are not really speaking for themselves. It is their addiction speaking for them. It is that little addicted voice inside their minds rationalizing the addiction, because they know, it might hurt to quit. They know that there will be a sense of loss. They know that smoking is as much a part of their personality as being a happy person, or being a morning person, or liking to go to the movies. Smoking becomes a part of who and what you are, An addict. It amazes me the number of people who smoke ciga ...

... of all a rainbow is a curve of colored light which is seen in the sky. Rainbows can be seen in moonlight or in artificial light. They are caused by the sun shining through tiny drops of water in the air. A rainbow's brightness depends on how large the drops are. The larger the drops are the brighter the rainbow will be. Many people think that a rainbow is only made of six colors, but it is really make of seven. The colors in order are red, orange, yellow, green, blue, indigo, and violet. A primary rainbow is a rainbow with red on the outside and violet on the inside. The largest rainbow visible to obs ...

... issues of the 20th century (Epstein 1). Many believe that continuing to provide genetically constructed inventions in this world is ethical, which means that these inventions conform to one’s moral standards (Epstein 5). Others argue that such inventions as human clones, which are genetically constructed humans, and other genetically created figures, are wrong and should be stopped (Epstein 5). Overwhelming textual evidence proves that genetic engineering is not beneficial to society. Accordingly, genetic engineering is unethical and therefore should be stopped. One reason why genetic engineeri ...

... decide now is whether to isolate probes for the other chromosomes, or whether we should utilize the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing ...

... blown easterly towards the western seaboard. Also, the Jet Stream is altered so that it blows directly over the Atlantic Ocean, thus dramatically decreasing hurricanes for that year. But when the warm waters brought on by El Nino recede, the cold waters of the Pacific Ocean move eastward and bring with it La Nina, the little girl. La Nina has a variety of different names such as El Viejo, anti-El Nino or simply "cold event". When the warmer Pacific water is pushed westward by the trade winds, that water flows toward Asia and makes room for the colder, deep sea water, to rise and flow to the Americas. Because c ...

... a kind of pyramid, or hierarchy, in which the different levels should represent the different degrees of evolutionary relationship. The hierarchy extends upward from several million species, each made up of individual organisms that are closely related, to a few kingdoms, each containing large assemblages of organisms, many of which are only distantly related. Carolus Linnaeus is probably the single most dominant figure in systematic classification. Born in 1707, he had a mind that was orderly to the extreme. People sent him plants from all over the world, and he would devise a way to relate them. At the age of ...

... two seasons all year either summer or winter. When we stepped out of the car we could see and hear birds singing. We could also smell, hear, and see the beautiful trees swaying in the gentle breeze. Pictures of a robin and a cardinal that we saw while stepping out of the car. We all got our gear out of the car and walked over to the trails. We had to decide what trail to take. We had three choices the first trail was half a mile long, the second trail was two miles long, and the third trail was four miles long. Since it was such a beautiful day we all decided to take the third trail that was four mi ...

... found a surprising order in the chaos that develops in the human heart, the prime cause of a sudden, unexplained death. Ecologists explored the rise and fall of gypsy moth populations. Economists dug out old stock price data and tried a new kind of analysis. The insights that emerged led directly into the natural world- the shapes of clouds, the paths of lightning, the microscopic intertwining of blood vessels, the galactic clustering of stars." (Gleick, 1987) The man most responsible for coming up with the Chaos Theory was Mitchell Feigenbaum, who was one of a handful of scient ...

... to Edmonton was out of the question. The nearest large airport was at Winnipeg, so they radioed ahead and changed their course. In a few minutes, all four of the fuel pumps had failed. The worst possible news, they were out of fuel. In a few more minutes the engines stopped running, and all of the high tech instruments became useless. They realized that they could not even make it to Winnipeg. Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a race track, complete with race cars, fences, and spectators. The 767 crash landed, and, fo ...
