... DNA is everywhere in a persons body, and can not be replicated. It is unique to every person, but all blood relatives have similar qualities that make them identifiable. (Joe Mickel and John F. Fischer, 1998) DNA stands for deoxyribonucleic acid, and it basically looks like a twisted ladder, or a double helix with rungs or base pairs. Guanine (G), Adenine (A), Thymine (T), and Cytosine (C) are the four bases that make up the base pairs. The bases don't just pair with any other bases, there are certain predictable combinations: A with T and G with C, and these are true to any DNA. The human body contains in excess of three billion base pairs, only a few of these are what attract foren ...

... Mercury is used in thermometers because the change in volume for each degree of rise or fall in temperature is the same. The use of mercury in the thermometer instead of alcohol was done by Gabriel Daniel Fahrenheit in 1714. It was also used in vacuum pumps, barometers, and electric rectifiers and switches. Mercury is used in a mercury-vapor lamps which are used as a source of ultraviolet rays in homes and for sterilizing water. Mercury-vapor is also used instead of steam in the boilers of some turbine engines. Mercury is sometimes used for amalgamation. Amalgamation is a metallurgical process that utilizes mercury to dissolve silver or gold to form an amalgam. This process ...

... would wonder why someone would want to be a botanist. The main reason anyone can name is that plants have intrigued people for thousands of years. Plants are used for decoration, as well as our basic needs, such as: food, shelter, and even the air we breathe. Today, our world requires new needs for plants. Increasing human population is linked to gigantic environmental problems. Among them is the need for more food to feed the world. Pollution of both air and water is becoming increasingly harmful to surrounding plant areas. New and improved technology is helping us solve these problems, but they will still need young minds to use that technology for the better good of humanity. ...

... had a circumference of 17 inches and weighed 1.51 pounds (Dennis 54). Hail can be extremely dangerous. It can break windows, damage roofs, dent cars, injure and even kill people! Crops are greatly affected. Hail causes around two hundred million dollars in damage a year. That's a lot of money. When the wind is blowing hailstones are at their worst. The most common places to see hail is in Texas, through the Great Plains and up into Alberta, Canada. Areas in the east of the high plains tend to have most of their hail in the spring. Southeastern Wyoming, western Nebraska, and eastern Colorado also have massive amounts of hail falling mostly during the summer (Merit ...

... helix. The DNA helix is then repeatedly coiled to allow more of it to fit into a compact space. This helix replicates and passes on its information to the body's cells. In humans, all the DNA is packaged into 46 separate molecules called "chromosomes." The chromosomes each contain thousands of genes, with each gene specifying how to make a particular protein necessary for cellular function. Scientists have long thought that the key to understanding human life lies in knowing the entire sequence of human DNA. Let's take a look at some of the things that people are able to do with or to DNA, as well as the things still in the realm of science fiction. From a variety of applications of kno ...

... one above. People who have genetic disorders are born with them. The inherited genetic defect causes a chemical error in all the cells in their body (Silverstein, 1994; Wagner, Reynolds, Moran, Moss, Wine, Flotte, Gardner, 998; Shapiro, 1991; Drake, 1995). In children and adults with CF, a mistake in a single gene disables a type of protein that functions as an ion channel. This molecule regulates the balance of salts in a special type of cell that lines many of the body's glands (Hopkin, 1998). All people with genetic disorders have inherited the defective genes from their parents, who in turn had inherited them from their parents, and so on, stretching back many generations. Notice Fig. ...

... meters. You can hear ripping, rending, wrenching, screeching, scraping, tearing sounds of a vast machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature’s arsenal, hydrogen. Near-molten fuel fragments shatter nearly incandescent graphite, torching chunks of it, exploding the hydrogen. The explosion breaks every pipe in the building rocking it with such power that the building is split into sections (11-13). You look down at your body and notice that it feels hot and your hands look different. Unknown to you a tremendous amount of neutrons are hitting your ...

... Nagasaki killed an average of 70,000 people. In these two blasts, entire families perished, leaving no one to report the death until four months from the catastrophe. This has made the Atomic Bomb the most powerful weapon ever invented in mankind. Secondly, countries that produce these bombs are harming others as well as themselves if there was war. For example, if a country fires an atomic bomb on another country, both of the countries will become affected with radiation and other nuclear gases. There is no need to produce these bombs because they are harming everybody in the world. Thirdly, Atomic Bombs have diverse effects on the soil and land. First, once an atomic bo ...

... and what we get from current institutions, a market-based alternative called "idea futures" is suggested. It is described through both a set of specific scenarios and a set of detailed procedures. Over thirty possible problems and objections are examined in detail. Finally, a development strategy is outlined and the possible advantages are summarized. THE PROBLEM THE SCIENTIFIC REVOLUTION Four centuries ago, some Europeans complained that the existing academic institutions were biased against them. Insiders, it was said, were "inflated by letters" and shunned anyone who dared "speculate on anything out of the common way" [De]. Outsiders -- astrologers, chemists, and p ...

... condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the ground each winter. There is evidence that in the past a denser Martian atmosphere may have allowed water to flow on the planet. Physical features closely resembling shorelines, gorges, riverbeds and islands suggest that great rivers once marked the planet. is smaller and, because of its greater distance from the Sun, cooler than the eearth. It has seasons similar to Earth's because the tilt of its rotational axis to the plane of its orbit about the Sun ...
