... generating plants, industrial commercial, and residential fuel combustion together contribute the rest of the nitric acid. In the atmosphere, the sulfur dioxide and nitrogen oxide transforms into sulfuric acid and nitric acid. Air current can send them thousands of kilometers from the source. When these acids fall to the earth, they will have large impact on the growth and the preservation of certain wildlife. These substance's can neutralize acids entering the body of water, thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little topsoil; there is not enough buffering capac ...

... experimentation there is always a risk. This risk involves the animals life and its right to co- exist with humans. That is the same right that we have to be free and choose our actions. In our past history and even still to this very day risky experiments are done on animals. The thousands of animals put to suffer outweighs any of the research that has been gotten from them. Peter Singer the author of a piece called “Animal Experimentation” in the book Intervention and Reflection displays and evokes the actual suffering of many harmless animals. "In 1953 R. Soloman, L. Kamin, and L. Wynne, experimenters at Harvard University, placed forty do ...

... male's dorsal fin can reach seven feet tall and stands straight up off the middle of his back. The female's dorsal fin is much shorter, usually about three feet, and instead of standing straight, forms a crecent arc on her back towards the tail. Although Killer Whales are not used for oil-based products they have over and over again been found with harpoons sticking out of their backs. Research soon found that fishermen were shooting them to keep them from eating all of a days catch. This was not the first time something like this was found. In the 1950's The U.S. Navy used machine guns to slaughter hundreds of Killer Whales off of Iceland to protect fishing. Aft ...

... the holes in the celestial realm. It is not perfect like people believed it to be. If the moon had all of these imperfections, then any other member of the universe could also be this way. It also showed the Earth to be just a planet. Not the unique figure thought to be. It is not unique. In fact, it was regular because the moon also had the same properties. The second observation was the four moons of Jupiter. Galileo observed points of light that changed their positions with time around the Planet. These points he concluded were the four moons that orbit Jupiter. It showed that there were things in the heavens that Aristotle knew nothing about. The was not unique ...

... the layer of air nearest to the earth surface, to the stratosphere. Air in the stratosphere absorbs solar energy, or heat from the sun, which in turn creates a photochemical reaction that produces ozone – a benefit to the environment since ozone protects people, plants, and animals from harmful radiation. The ozone layer is important because it absorbs most of the damaging ultra-violet radiation from the sun before it reaches ground level, where it can cause sun burn, skin cancer and cataracts. Research suggests that any additional UV-B (ultra-violet radiation) at ground level could depress our bodies’ immune systems, damage the natural food chain and r ...

... wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that nourish the muscles are located. As this area degenerates it leads to scarring or hardening ("Sclerosis") in the region. Over 5,000 Americans are diagnosed with ALS each year. There is great variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, on average, two to five years. Progression of ALS varies with each individual; therefore, some will live longer--up to 10 years, and about five perc ...

... halogen family, and like all the other halogen elements chlorine has a strong tendency to gain one electron and become a chloride ion. Chlorine readily reacts with metals to form chlorides, most of which are soluble in water. Chlorine also reacts directly with many nonmetals such as sulfur, phosphorus, and other halogens. Chlorine can support combustion; if a candle were to be thrown into a vessel of chlorine, it would continue to burn, releasing dense, black clouds of smoke, The chlorine combines with hydrogen of the paraffin, forming hydrogen chloride, and uncombined carbon is left in the form of soot. Soot is black residue from fuel. Chlorine replaces iodine a ...

... of a DNA molecule, a mRNA molecule is built. This is accomplished by an enzyme which travels along a portion of DNA between two exons and attaches the opposing base pairs to the backbone of the mRNA (a structure composed of phosphates and ribose). The nitrogen bases of this new molecule are identical to that of the opposite side of the original DNA molecule except that the thymine has been replaced with uracil. The formation of this molecule allows for the construction of proteins in the ribosome without risking the DNA in the cytoplasm. The mRNA travels through the cell to a ribosome. Here tRNA which contain the appropriate anti-codon collect the amino acids code ...

... grown into the creation of nuclear weapons that are potentially 40 times more powerful than the original bombs used. However, a military change in strategy has came to promote nuclear disarmament and prevent the usage of nuclear weapons. The technology of building the atomic bomb has spurred some useful innovations that can be applied through the use of nuclear power. The fear of a potential nuclear attack had been heightened by the media and its release of movies impacting on public opinion and fear of nuclear devastation. The lives lost after the detonation of the atomic bombs have become warning signs that changed global thinking and caused preventative act ...
