Alcoholism 4
Number of words: 1374 - Number of pages: 5

.... vital functions such as pulse rate, respiration, and blood pressure (Kestler 6). The body can absorb alcohol very quickly, approximately 20% goes directly into the blood stream from the stomach, the rest enters the body through the small intestine. Moments after alcohol enters the blood stream it reaches the Cerebral Cortex, the part of the brain responsible for judgement. The areas of the brain controlling caution and self control are effected first, so most people feel more relaxed. Extremely large doses of alcohol may result in coma or death (Knox 42). Intoxication varies greatly fr .....

.... have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586) Nuclear power plants generate only about eleven percent of the world's electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms' nucleus' split and cause a nuclear reaction. (General Information) When a free neutron splits a nucleus, energy is released along with free neutrons, fission fragments that give off beta rays, .....

.... 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 list of what exactly the consumes is quite extensive. Eighty percent of their diet is rodents. However, they will eat pretty much whatever they can find. Watermelons are also a food source for this omnivorous and carnivorous species. As one of my sources puts it, the takes what it can get (Jones, 1999). Sheep, road kill, insects, domestic cats, apples and your garbage are .....

Gravity
Number of words: 1275 - Number of pages: 5

.... 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 feathers, leaves, and sheets of paper fall more slowly than pennies, acorns, and crumpled balls of paper. There is another legend that states that when Newton was lying against a tree in an orchard, he was struck on the head by an apple. He wondered what provided the acceleration for the apple to fall to the ground. Was this a force of the earth on the apple? If so, then .....

Destruction Of The Ozone Layer
Number of words: 1143 - Number of pages: 5

.... the ozone layer revolves around whether human-made CFCs (chloroflurocarbons) used in air- conditioners and refrigerators are breaking it down. This is the ozone thinning theory: "CFCs release chlorine into the stratosphere... leading to ozone destruction and exposing the planet to harmful ultraviolet rays." Critics who discount the thinning theory still say that chlorine comes from natural sources like volcanic eruptions and does no permanent damage (Brooks 422). NASA researches claim that they have evidence that shows CFCs are to blame for ozone depletion. Natural chlorine is only about .....

Millennium Bug
Number of words: 692 - Number of pages: 3

.... properly when the date rolls over. Local testing has identified the ultrasound machines and central monitors which have exhibited year 2000 failures. There could be significant threats to personal safety, for example if an ultrasound wrongly calculated the size of a faetus or administered radiation therapy incorrectly. Also people with heart pace makers could face the possibility of them failing. Bank accounts could be wiped off the records and ATM's could swallow cards thought to be expired. Computers controlling home loans could strip banks off millions of dollars by resetting mortgage r .....

All About Ants (almost)
Number of words: 2889 - Number of pages: 11

.... are found in some form on all continents and all habitats but the extreme arctics. Their success is manifested in the claim that at any time there are at least 1 quadrillion living ants on earth(Groliers Œ93). All species of ants are social. They live in organized communities or colonies, which may contain anywhere from a few hundred to more than 20 million individuals. These are organized into a complex system which may contain two or more castes and sub castes which can be roughly organized into three groups. Queens, males and workers. The queen is much larger than the other ants .....

Inventions And Their Importance
Number of words: 1810 - Number of pages: 7

.... was one of the main reasons for invention. The economic inventions needed were devices, machines, business, and industry-processes and products. The majority of economic inventions collaborate with one another; a lot of things were invented to make other inventions work. Another major reason people invent is to satisfy military needs. During war times engineers, scientists, and inventors are brought together and their only duty is to invent military weapons. The weapons that the scientists come up with have to be more powerful and destructive than the enemies, with both sides striving to .....

Cardiovascular Disease

.... are inactive and out of shape. With routine exercise you can reach a level of physical fitness comparable to an active person ten to twenty years younger. Regular exercise may also lower your cholesterol and blood pressure, and reduce the risk of diabetes. Exercise increases the size of coronary arteries and reduce clogging due to atherosclerosis. Exercise also increases the efficiency of your blood's oxygen-carrying capacity and your muscles' uptake of oxygen. Exercise has been linked to increased levels of high density lipoprotein (good) cholesterol and decreases low-density lipop .....

Coconino Sandstone
Number of words: 1125 - Number of pages: 5

.... ancient sand seas, or ergs, have increased greatly our understanding of eolian bedform dynamics. Additionally, we can describe trace fossils in the Coconino and relate them to the physical environments of deposition. This provides us with more comprehensive reconstruction of the erg environments. Although the cliff-forming nature of the formation can present certain logical problems, the exceptional three-dimensional exposures in the Grand Canyon give the sedimentologist and ichnologist the opportunity to examine the details of one of the more classic and interesting eolian deposits on the .....
