.... 1). It is extremely hard to prove, however, that dioxin is responsible for the countless illnesses acquired by many Vietnam veterans because each individual has their own tolerance to dioxin (Vancil, 1). Many soldiers in the Vietnam War encountered repeatedly. Their lives revolved around the 55-gallon drums, which once were filled with an extremely harmful herbicide. Unaware of the possible consequences, many soldiers built showers and hibachis out of these discarded drums (Doyle, 139). They also used the barren drums to store potatoes and watermelons (Doyle, 139). One man described to his wife how they would bathe and swim in water contaminated with because the ....

.... there were scientific theories for the cause of earthquakes, people around the world created folklore to explain them. Until recent times, science has not had a complete understanding of how earthquakes are caused, and what can be done to predict when they will strike. This essay will discuss how earthquakes are formed and occur, how scientists can more accurately predict the arrival of earthquakes. Before contemplating how earthquakes might possibly be prevented, it is essential that the process and formation of and earthquake be understood. Earthquakes are caused when the earth's crustal plates move, rub, or push against each other. The earth's crust (the outer lay ....

.... person every forty-five seconds. The Centers for Disease Control (CDC) estimate that seventy to eighty percent of the common diseases killing Americans can be prevented by a responsible lifestyle and diet. Drug testing on animals is not accurate and has no advantage to animals or people. Animals including dogs, cats, mice, pigs, monkeys, horses, deer, and cattle are commonly used for these senseless experimentations. The other remaining misfortunate animals come from places a little closer to you and me. Some of them come from animal shelters, some from the “free to a good home” ads in the newspaper, or, even worse, some have been stolen directly from their o ....

.... is Ksp = [Pb][I]2 This gives the relationship between the ions in the saturated solution and is the maximum concentration possible without creating precipitation. In this lab, solutions of lead nitrate and potassium iodide will be mixed at a number of dilutions. The reactions will then be observed to see at which point a precipitate no longer occurs. Ksp will then be stated as a range of values at room temperature, and the precipitate test tubes will be heated until the precipitate is dissolved so that Ksp may be observed and determined at different levels. In this experiment various solutions of lead nitrate and potassium iodide were mixed at a number of different di ....

.... we learn through our senses is not Wisdom. The reason behind this was Aristotle knew that knowledge obtained through the senses can only tell a person the "that" of anything and not the "why;" for example; We all know "that" fire is hot but do we know "why." We also know "that" water is wet but "why" is it wet. These were questions that nobody obtained the answers to but Aristotle was determined to know, and having this type of knowledge would truly earn the title of PAGE 1 Wisdom. Now finding the knowledge and answers would be very difficult but Aristotle believed what better way to obtain this then through the use of science. He knew that everything in science deals with le ....

.... and sensation (Hunter, 1993). The duration of the clinical disease varies with each case, but most commonly lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991). After extensive research, the pathology of BSE was finally determined. Microscopic lesions in the central nervous system that consist of a bilaterally symmetrical, non-inflammatory vacuolation of neuronal perikarya and grey-matter neuropil was the scientists' overall conclusion (Stadthalle, 1993). These lesions are consistent with the diseases of the more common scrapie family. Without further investigation, the conclusion was made that BSE was a new member of the ....

.... from the soil (EPA). When the trees weaken from the acid, it has a harder time fighting off adversaries such as fungi, diseases, and frost so subsequently it dies. Around the 1970s the acid rain dilemma got worse, the acid rain has put trees in danger and now they are starting to die off. The effects of acid rain on a tree is shown if it has less foliage, yellow spots and produces many cones (Baines, 22). Secondly, acid rain damages the trees through the soil by releasing metals that harm them even further (Lucas, 72). Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds come instead, this process is c ....

.... the most in the discovery. Crick seemed to be a loud and out spoken man. He never was afraid to express his opinion or suggestions to others. Watson appreciated Crick for this outspoken nature, while others could not bear Crick because of this nature. Maurice Wilkins was a much calmer and quieter man that worked in London at King's College. Wilkins was the initial person that excited Watson on DNA research. Wilkins had an assistant, Rosalind Franklin (also known as Rosy). Initially, Wilkins thought that Rosy was supposed to be his assistant in researching the structure of DNA because of her expertise in crystallography; however, Rosy did not want to be thought of ....
