... while its running. And of course the most famous of the automobiles evils is the exhaust. The toxic fumes given off as a byproduct of the combustion engine are slowly deteriorating our lungs and our atmosphere. The exhaust is extremely toxic to human beings. But why do we do continue to drive these walking time bombs. Some people will say it is progress, but the majority drives it for the convenience. Why walk four miles in four hours when you can drive the same miles in four minutes? Another popular source of waste is the post-consumer market. American citizens throw away millions of tons of garbage each year, and ...

... force acts in the opposite direction to that of the object's motion. In the case of a falling object, air resistance pushes up as pulls down, which causes the object to slow down. When Galileo's experiment was repeated on the moon, the hammer and the feather hit the ground at the exact same time. This is due to the fact that the moon has no atmosphere. Therefore, air resistance doesn't exist on the moon. Also, the amount of air resistance on an object depends on the speed, size, shape, and density of the object. The larger the surface area of the object, the greater the amount of air resistance on it. This is why ...

... they are born with great accuracy. What is on the horizon now, is the possibility of designing your child to be “perfect”. Over the years, there has been heated, ethical controversy on each of these issues, especially designer babies. How far will we let biotechnological discovery take us? What will come of the world if designer babies become standard procedure? The earliest and maybe simplest use of genetic manipulation was in the selection of the sex of an unborn child. In Vitro Fertilization(IVF - A procedure in which a woman’s eggs are removed from her body, fertilized outsi ...

... or concentrated sulfuric acid but is resistant to alkalies. Mercury melts at -39C, boils at about 357C,and has a gravity of 13.5. The atomic weight of mercury is 200.59. Mercury comes in its pure form or combined with silver in small amounts. It is mostly found in the form of the sulfide. Mercury has many uses and is a very important element. A major use of mercury is in electrical equipment such as fluorescent lamps, and mercury batteries. Mercury is used in thermometers because the change in volume for each degree of rise or fall in temperature is the same. The use of mercury in the thermometer inst ...

... generation of electricity which made tremendous improvements to communications throughout Canada. The electric telegraph, first discovered in 1837 by Samuel Morse, was a great improvement over the mechanical telegraph which required the use of a telescope and was much less effective. It encodes messages electrically, transmits them over facilities such as copper wire, coaxial cable, and fibre optics to their destination where they are decoded into their original form. Combinations of long and short bursts of electric current are sent through a circuit thereby encoding each letter of the alphabet. More eff ...

... decreased night vision and ultimately blindness. Poor kidney function and kidney failure may also arise due to thickening of the blood vessels in the kidneys. Protein leaks into the urine and the blood is not filtered normally. Skin is greatly affected by diabetes Mellitus. There is poor blood flow to the skin which causes loss of feeling. Sores and deep infections called diabetic ulcers occur because of this. Pregnancy is affected by diabetes Mellitus. Many changes that take place during pregnancy make controlling blood sugar more difficult for a woman who has diabetes. Changes in the levels and types of horm ...

... explanation, I decided to investigate the topic further. I went to Palmer College of Chiropractic's library hoping to consume as much information as possible to prove Parents' Magazine wrong. I found several medical journals, psychiatric journals, and books on the topic of eating disorders that could affirm my feelings. As I tried to rationalize my friend's behavior, I decided that social acceptability had to have played a large part in her illness. I also took into account that her mother had passed away about 7 years before she broke her news to me, and she had also given up her crown as Miss ...

... This is because the gene responsible for making blood factors 8 and 9 are only found on the X-chromosome. If a female is a carrier that means that she has one bad gene and one good gene for this disease. There is a fifty percent chance that she would pass it on to her child because she can only pass on one of the two chromosomes. If a male has hemophilia, he will have normal sons and all of his daughters will be carriers of the hemophilia disorder because all he can pass on is the defective X-chromosome. Males mostly have hemophilia, but women can also have hemophilia. This is extremely rare ...

... without any original grounds for belief. Over time more and more people looked into evolutionism and they developed possibilities of how it occurred. Many theories were developed, but someone always disproved them. Recently with the discovery of genetic mutation and a new understanding of genes and DNA, the evidence supporting evolution has greatly increased. Charles Darwin was one scientist who helped to increase the evidence supporting evolution. Darwin developed the idea of “natural selection� where living things that reproduced in large numbers and survived became dominant and other li ...

... background rate of extinction (Lampton 14). Species have slowly evolved and disappeared throughout geological time because of climate changes and the inability to adapt to survive competition and predation. Since the 1600's, however, the rate of extinction has accelerated rapidly because of human population growth and resource consumption (17). Today, most of the world's habitats are changing faster than most species can adapt to such changes through evolution, or natural selection. The current global extinction rate is estimated at about 20,000 species per year, exponentially greater than the background extinct ...
