... with other elements. For example, the carbon dioxide in the air is a compound of carbon and oxygen. Other compounds containing carbon include minerals such as limestone, and fuels such as coal and petroleum. Carbon compounds make up the living tissues of all animals and plants. There are over one million known carbon compounds (still growing rapidly every year), which is over the sum total of all the other elements combined. The largest group of these compounds are the ones composed of carbon and hydrogen. Carbon also forms another series of compounds, which is classified as inorganic, but is a much smaller number than the organic compounds. These millions of compounds combine in ...

... was not needed. The problem in keeping a creature such as the Woolly Mammoth in a zoo- like surrounding would be poachers. Due to the endangerment of such a magnificent species, poachers of pelts and ivory would most certainly be after it's huge tusks and thick furs, so it would be necessary to post guards around it's cage at all times. A large-scale habitat would be constructed for this creature since, during the period it lived, the Pleistocene, there were no restrictions on the places it could roam to. There was nothing stopping this beast from stomping along to wherever it wanted to go. A Woolly Mammoth might find it peculiar to be stuck in a twenty foot ice field with no predato ...

... probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copies of a particular chromosome, which is normal, or one or three, which is abnormal. A test using Willard's probes would require only a few cells and a few days to detect abnormalities. "I don't think it's beyond the realm of possibility that these kinds of tests could eventually be done by an obstetrician in the office during the early stages of pregnancy," he adds. The determination of gender is another po ...

... of all major automobile accidents, and murders are associated with . On and on the statistics point to the enormous dangers of , yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is dependent. The life span of the ic is about ten years shorter than the non-drinker. The lifetime prevalence for ism in the United States is as high as fourteen percent. Taking these statements into consideration it is not difficult to believe that is ranked the third major cause of death in the United States. Not so suprising is the fact that approximately thirty seven percent of abusers suffer from at least one co-existing ...

... cancer is Hereditary Non-Polyposis (HNPCC). HNPCC accounts for five to ten percent of all cases. HNPCC develops also at a young age but not as young as FAP patients. The actual cancer appears in the persons 40's. HNPCC is known as a "fast growing" form of cancer. Along with colon cancer HNPCC patients are also at a much higher risk for other forms of cancer. Page 2 The causative factors of these cancers are not known at this time. Many doctors, scientists, and medical researchers believe individuals who fall into high-risk categories might be more apt to get colon cancer. These categories include high-stress lifestyles, certain diets, and gastrointestinal disorders. Diets included ...

... did the possibilities of CADD. Images on CADD systems are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line will be while the operator inputs the length of the line. Lines are the basis of all drawings. Straight lines are fairly simple and quick to make, but what about curved or wavy lines? That's what different CADD commands are made for. Different CADD commands make different things on the screen possible. There are commands for dimensioning, labelin ...

... and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce visibility by attenuating the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to reduce. Not only does it effect visibility, but it hastens the erosion of building materials and the corrosion of metals, interferes with the human respiratory system, and brings toxic materials into the body. The small particles cause chronic bronchitis, bronchial asthma, emphysema and lung cancer (Hodges 59). The second type is sulfur o ...

... 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 Colorado Plateau. Lithology This layer averages about 260 million years old and is composed of pure quartz sand, which are basically petrified san ...

... If the old growth forests are gone, then they can never return because it takes over five generations to produce one and at the rate that the human population is increasing, there is not enough land to have a secure place for a new forest. If we realize that it is best for the human race to stop destroying the natural resources, then we must destroy, too, the existence of loggers all together. To do so, there must not be any new loggers, so all training potential loggers must be stopped. The current loggers must be diverted to another occupation. Perhaps if the public supported the notion of stopping clear-cutting, the government would be able to provide services to educate the logge ...

... energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point because of the equilibrium achieved by itself. The gravitational pull from the core of the star is equal to the gravitational pull of the gases forming a type of orbit, however when this equality ...
