.... ones. The paragraphs below will prove that the construction and presence of dams always has and will continue to leave devastating effects on the environment around them. Firstly, to understand the thesis people must know what dams are. A dam is a barrier built across a water course to hold back or control water flow. Dams are classified as either storage, diversion or detention. As you could probably notice from it's name, storage dams are created to collect or hold water for periods of time when there is a surplus supply. The water is then used when there is a lack of supply. For example many small dams impound water in the spring, for use in the summer dry mon ....

.... of the temperate deciduous forest. This forest type once covered large portions of Eurasia, South America, and North America. As with most native forests, they have been cleared so that the land could be used for farming or residential use. The temperate deciduous forests of North America were more diverse than the same type of forests in Europe due to glacial history. Glacial action dumped till as the ice edge retreated, and North America inherited a fertile soil base. Soil type is an important factor for which species of trees can thrive in an area. The general dominant tree species for temperate deciduous forests are Beech, Ash, Oak, and in our region also Tulip, Maple ....

.... during 1946. This powerful type of energy comes from many things such as atoms and subatomic particles; an atom is a tiny bit of matter that has very little weight. They are much too light to be weighed directly, but scientists have developed methods of determining these tiny weightd by using special labratory instruments. Hydrogen is the lightest of all atoms and carbon atoms weigh twelve times more than the hydrogen atom. Atoms that make up one alement are not like atoms that make up another element. These (atoms) are not simple particles, their structure is very complexe. They are, in fact, made up of smaller bits of matter called subatomic particles. An atom ha ....

.... miles off San Francisco, is a common feeding ground for the great white. The coastal waters along central California, especially around the Ano Nuevo State Reserve and along the Marin Headlands, are another common area for white sharks. In the summer the sharks move to the coasts of Oregon and occasionally the Gulf of Alaska, and in the fall, they turn south and move along the offshore islands. They are also found in great numbers in the Australian waters. The great white is a very agile killer that hunts mostly anything in the ocean. They are carnivorous and usually prey on sick or injured prey. Just one drop of blood can make the shark ....

.... Genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering, and embracing its possibilities for society, is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is d ....

.... a component of ribonucleic acids and several vitamins; and deoxyribose, a component of deoxyribonucleic acid. Among the most important aldohexoses are glucose, mannose, and galactose; fructose is a ketohexose. Several derivatives of are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a monosaccharide, include sorbitol (glucitol) from glucose and mannitol from mannose; both are used as sweetening agents. Glycosides derived from are widespread in nature, especially in plants. Amino sugars (i.e., sugars in which one or two hydroxyl groups are replaced with an amino gr ....

.... their energies can be used according to the kind of energy they emit. Since the mid 1900's radioactive wastes have been stored in different manners, but since several years new ways of disposing and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both boric a ....
