.... of course, inadequately trained and experienced operators. As a result of these risks, all special effects are regulated at the federal, state and local level. In general, all are explosives, but not all explosives are . Class A explosives (high explosives) are materials like dynamite and Primacord which may detonate even if unconfined. Pyrotechnic special effects materials are Class B explosives. They will burn, but not explode unless confined. Examples are black powder and pellet powder, safety fuses, igniters, igniter cord, fuse lighters, Class B special fireworks, and Class B composite solids propellants. Class C explosives are common fireworks. N .....

.... of an organism, or its metabolic rate (Grolier1996). Metabolic rate is directly linked to the core temperature in an animal. An ectotherm, or cold blooded animal, warms its body mainly by absorbing heat from its surroundings. The amount of heat it derives from its metabolism is negligible. In contrast, endotherms derive most or all of its body heat from its own metabolism (Campbells,p899). Because ectotherms do not produce their own heat, they cannot actively ensure their ideal temperature for an ideal metabolic rate (aquacult.htp). In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental tem .....

.... levels over time and causes sever damage to the central nervous system. Mercury's Effect on the Environment and People Mercury is one of the biggest environmental problems that exist because it is hard to get of once in the environment. In the past, mercury was used to make things like paper, put in paint and thermometers, and as an agricultural pesticide. The Minamata Disease is a good example of what could happen if mercury enters into the environment. In the mid 1950's, more than 100 Japanese were poisoned by fish that contained methyl mercury. The mercury came from industrial waste that had been dumped into the bay where the fish were caught. The .....

.... for normal functioning. At times, an underlying illness or disease can cause persistent anxiety. Treatment of the illness or disease will stop the anxiety. Anxiety illnesses affect more than 23 million Americans with about 10 million Americans suffering from the most common, general anxiety disorder . (Harvard, 1). Common are panic attacks (panic disorder), phobias, and general anxiety disorder (GAD). Panic attacks can begin with a feeling of intense terror followed by physical symptoms of anxiety. A panic attack is characterized by unpredictable attacks of severe anxiety with symptoms not related to any particular situation. (Hale, 1886). The perso .....

.... chloroform, and carbon tetrachloride are used as solvents for cleaning, carbon tetrachloride is also a feed stock for the production of CFC-11 and CFC-12. CFCs are released in relatively small quantities, but one kilogram of the most common CFCs may have a direct effect on climate 1000 times large than that of one kilogram of carbon. In addition over the last two decades the percentage increase of CFCs in the atmosphere has been higher than any other greenhouse gas. By 1990 the increase was 4-12% a year. CFCs also destroy ozone - itself a greenhouse gas - their net effect on climate is unclear. The strength of the indirect effect of oz .....

.... it is (Patrick, 1999). Animal researcher, Bil Gilbert, calls the the great-granddaddy of what he calls, invigorated species (Gilbert, 1991, p. 69). These are animal types that are doing better than ever before in categories such as reproductive rates and widespread distribution. Gilbert offers a similar explanation as to why the is the most prolific of the invigorated species. Often s and many other invigorated species are referred to as "generalists." This has to do mainly with how and what they eat. In this respect, few other creatures have such catholic tastes or more ingenious methods of satisfying them as have s (Gilbert, 1991, p. 69). The .....

.... The biggest threats after a heart attack are arrhythmias and cardiac standstill. An abnormal heart rate and rhythms in a patient after a heart attack often means the left ventricle is not pumping adequately. Congestive heart failure may be a threat at this time. Symptoms of a heart attack may begin suddenly, with a sharp, sever pain in the chest which may radiate to the left arm and shoulder. Other symptoms may include restlessness and confusion; the skin may be cold and clammy, dyspnea, cyanosis, a drop in blood pressure, and a drop in body temperature. A rapid and irregular pulse may also be a sign of a resent MI. In the beginning of the twentieth c .....

.... After obtaining a degree, your next step would be to find a job. According to Jerry Murphy, if you want an easy way into the chemistry field you need to know someone already in that occupation. For the most part in Missouri, employment is increasing. Nevertheless, if you are not restricted to finding a job in Missouri, in the United States a whole employment is expected to increase 21% (Choices). After finding a job in the chemistry field that you will enjoy another quesiton arises, money. On hte average if you begin working at a entry level job witha bachelors degree your salary will be somewhere around $24,000 a year. If you start work with .....
