Acid Rain 4
Number of words: 1614 - Number of pages: 6

.... the international, industrial, and personal levels. Just how does acid rain form, and what consequences does it pose to our environment? There are numerous theories as to the cause of acid rain. However, the most prevalent is the theory that electric generating plants, heating plants, and other industrial plants have been emitting an excess amount of sulfur oxides, nitrogen oxides, and volatile organic chemicals (VOC�s) into the atmosphere. Once these chemicals are in the air, they react with water to form acids and fall back to the earth as precipitation. P .....


Chemical Warfare
Number of words: 385 - Number of pages: 2

.... of these are called blister agents, which cause big blisters on your skin. A blister agent called mustard gas caused a lot of deaths on both sides during World War I. Some other chemical agents can cause temporary blindness or mental confusion. But people still can defend themselves against all of these chemical agents. For example, gas masks, other protective coverings for the body, and injections of antidotes are used as defenses against chemical agents. Chemical agents also have nonmilitary uses. For example, riot control agents, including tear gas, can be .....


Toxic Waste
Number of words: 530 - Number of pages: 2

.... used in developing countries on the malaria-carrying mosquito. Oil spills also have harmful effects, luckily chemicals can neutralize the oil before massive damage occurs. In 1983 the Dow Chemical Company�s factory, a major producer of chemicals, showed contamination from dioxin. Dow undertook a 3 million dollar study of the material. The company announced that Dioxin is less health and life threatening. High-temperatures are used to reduce the toxicity of waste. These processes use plasma technology to make the waste more environmentally friendly. Plasma t .....


Cheetah 2
Number of words: 374 - Number of pages: 2

.... is regarded as one the fastest hunters in the world and of course, the fastest land animal in existence. I also found that it�s habitat is in the grassy plains of Africa. This is definitely a great place for it to hide based on it�s coat color. It is because of this combination of tall grass and camouflage coat which allows the cheetah to stalk and catch it�s prey. These usually consist of gazelles, wild boar, or pretty much any animal it can handle. However, the regular range for it�s food is about 88 pounds. The cheetah then drags the meat to it�s �ho .....


Longitude
Number of words: 834 - Number of pages: 4

.... Halley proved this theory wrong. After many observations, Halley concluded that the moon’s rate of revolution around the earth was accelerating overtime. John Harrison was a simple clockmaker and a self-educated person who was accredited for finding by means of a timekeeper. John built his first pendulum watch in 1713. It was constructed entirely out of wood. Harrison called his first sea clock Harrison’s No. 1 or H-1 for short. H-1 was bar-shaped, built out of shinny brass, and was big in size. His second attempt was called H-2. H-2 wa .....


Endocrine Disruption
Number of words: 2635 - Number of pages: 10

.... location will almost always have an effect on many other areas of the body, not just the surrounding tissues. An analogy that fits very well with the study of the endocrine system is that of a message in a bottle. We can think of the body as a river, and a specific hormone may be a bottle containing a message. The organs or glands mentioned above would manufacture the “bottles” (hormones) that would be released into the river (blood stream). If there were no receptor sites for the hormones in the body, then they would continue to flow along th .....


Hydrologic Cycle
Number of words: 773 - Number of pages: 3

.... Infiltration, however, moves under the force of gravity through the soil. If soils are dry, water is absorbed by the soil until it is thoroughly wetted. Then excess infiltration begins to move slowly downward to the water table. Once it reaches the water table, it is called ground water. Ground water continues to move downward and laterally through the subsurface. Eventually it discharges through hillside springs or seeps into streams, lakes, and the ocean where it is again evaporated to perpetuate the cycle. GROUND WATER AND SUBSURFACE WATER Most rock or .....


Microbiology
Number of words: 2025 - Number of pages: 8

.... microbiologist is a scientist who studies life forms that can only be observed by means of a microscope. Microbiologists use many criteria to classify bacteria. The Beginning of Microbiology Zacharias Jansen created the microscope. Although Robert Hooke is the one who made it widely known. In 1665 Hooke published a book called Micrographie. It contained his thoughts on chemistry as well as a description and list of uses for a microscope. With this he opened the door to microbiology. For the first time the world was able to see very small creatures .....
