.... science concerned with the dynamic behavior of bodies that are acted on by mechanical disturbances. Since such behavior is involved in virtually all the situations that confront an engineer, mechanics lie at the core of much engineering analysis. In fact, no physical science plays a greater role in engineering than does mechanics, and it is the oldest of all physical sciences. The writings of Archimedes covering bouyancy and the lever were recorded before 200 B.C. Our modern knowledge of gravity and motion was established by Isaac Newton (1642-1727). Mechanics can be divided into two parts: (1) Statics, which relate to bodies at rest, and .....

.... in ancient Sparta, sickly children were killed or abandoned.1 They filtered out the “undesirable� traits in children, a practice which has come to be called “negative .�2 In the late nineteenth century, a man named Francis Galton gave eugenic thought great emphasis.3 Yet it was not until Gregor Mendel’s theories on genetics were rediscovered by Charles Davenport in 1901 that the ideas of modern was given any credibility.4 Davenport conducted experiments that proved what Mendel had said years before in his laws of genetics. Davenport, however, took it another step. He extended Mendel’s laws to include characteristics such a .....

.... Harley and Klein (1990) microbiology is the study of organisms that are usually too small to be seen with the naked eye. According to Jenson and Wright (1989) a pathogen is a disease-producing organism. They also describe microbes as organisms that are often too small to be seen without the aid of a microscope. Microbes, also known as microorganisms, can be broken down into four classifications that are bacteria, viruses, fungi, and protozoa. Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in structure; they usually are .....

.... in the future. There are many things that we must take into consideration before geothermal energy can be a possibility for a human resource. I will be discussing some of these issues, questions, and problems. In the beginning when the solar system was young, the earth was still forming, things were very different. A great mass of elements swirled around a dense core in the middle. As time went on the accumulation elements with similar physical properties into hot bodies caused a slow formation of a crystalline barrier around the denser core. Hot bodies consisting of iron were attracted to the core with greater force because they were .....

.... and from nose to tip of the tail is 10 feet long. The tail alone is about 4 feet long. The kangaroo has a small head with large ears and a small mouth. The fur is soft and woolly and some can have stripes on them. The kangaroo's body is specially built for jumping. It has two long, powerful hind legs with four toes on each. The front legs are short and have five toes with claws. These paws are used to handle food. Most of it's weight it in the hind legs and tail. Kangaroos can jump across flat land up to thirty miles an hour. Even though it is quite timid, kangaroos can fight very hard. They use there paws to position an opponent, and then .....

.... are just a few of the chemical properties of nitric oxide. With the total life expectancy of nitric oxide being from six to ten seconds, it is not surprising that it has not been until recently that it was discovered in the body. The compound is quickly converted into nitrates and nitrites by oxygen and water. Yet even its short-lived life, it has found many functions within the body. Nitric oxide enables white blood cells to kill tumor cells and bacteria, and it allows neurotransmitters to dilate blood vessels. It also serves as a messenger for neurons, like a neurotransmitter. The compound is also accountable for penile erections. Further .....

.... have been changed and reorganized. Today biology is subdivided into hierarchies based on the molecule, the cell, the organism, and the population. Some of the more specific types of biology are as follows: Molecular biology, which has made the most fundamental contributions to modern biology; Cellular biology, which is closely linked with molecular biology. Cellular biology deals with the functions of the cell and the basic strucural unit of living matter; Finally, population biology became firmly established as a major sub division of biological studies in the 1970’s. This field relates with the study of gene changes in populations, and ecolo .....

.... forests with occasional open areas such as meadows. They occupy all of Canada starting from the tree line going south. They live in all provinces and territories except Prince Edward Island, where heavy de-forestation has happened and preferably away from brown bears (larger competitors). The only main risk for black bears are poachers who sell their parts illegally to the Asian medicinal market. In northern areas of Canada, the bear undergoes a remarkable metabolic transformation as it prepares for hibernation. Hibernation is an energy-saving process bears have developed to let them survive for long periods when there is insufficient food ava .....

.... beliefs whose Gods are all so varied and different that it is difficult to fathom that they are all the same divine being. It is also plausible that we just have a desire to quench the thirst for knowledge that lies deep within ourselves. As for myself, I cannot believe in a being which created a universe and a multitude of worlds in a rather short period of time then deigns to lower itself into becoming a puppet-master and "pulling the strings" of the Earth and all of the people therein. Since this paper touches upon many scientific terms, I feel that in order for the reader to correctly grasp the content I must first define three words: .....

.... egg. As early as 1952, two scientists, Robert Briggs and T.J. King attempted what Spemann had suggested with a frog embryo and egg. Unfortunately, the frog egg did not develop. (Specter/Kolata) That same year, researchers in Pennsylvania cloned a live frog. The technique used was known as embryo twinning, or causing the embryo to split apart. It is much easier to clone with embryonic cells. Much later, mammals such as sheep were cloned using this process. (Nash 64) In 1970, John Gurdon repeated the procedure suggested by Hans Spemann. This time, the experiment yielded partial success. The tadpoles were born alive, but they died when they be .....
