... of your lungs to close off and make it harder to breathe. The tall smokestacks used by industries and utilities do not remove pollutants but simply boost them higher into the atmosphere. These pollutants may then be transported over great distances, causing adverse effects such as acid rain in areas far from the emission site. The worldwide increase in the burning of coal and oil since the late 1940s has led to increasing concentrations of carbon dioxide. The resulting greenhouse effect has reduced the escape of infrared radiation from the earth, causing a possible global warming trend. The Prevention of Air Pollution To cut down on all the pollution being relea ...

... 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 dependant on ...

... to keep lurching ahead? "As a distraction from his sister's regime, Charles played solitary games in the vast family home. His father had become interested in the fashionable study of natural history and there were rooms full of exotic collections, stuffed animals and old bones. A massive greenhouse attached to the side of the house was a veritable jungle to a young boy and it was in this environment of learned eccentricity and an unforced seeking of knowledge that Darwin's fascination for natural history and biology began." (D 6) However, growing up in the family home of Dr. Robert Darwin, was not exactly the most pleasant aspect of young Charles Darwin's li ...

... into the computer. A file virus inserts virus codes into program files… The virus then spreads to any program that accesses the infected file. A Trogan horse virus (named after the Greek myth) hides within or is designed to look like s legitimate program. Some viruses interrupt processing by freezing a computer system temporarily and then displaying sounds or messages. Other viruses contain time bombs or logic bombs. A time bomb is a program that performs an activity on a particular date. A logic bomb is a program that performs an activity when a certain action occurs, such as an employee being terminated. A worm, which is similar to a virus, copies itse ...

... habitat. It has many related species and it’s geographic distribution is extremely wide and varied. The Aedes aegypti, with regard to both sexes, are generally similar in coloration (Womack 1993). The female adult is noticed by it’s small dark figure that is colored by white markings and banded legs. Its proboscis or snout is mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales present on the insect (Womack 1993, Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled ...

... should enjoy working as a plant physiologist, plant biochemist, molecular biologist, or chemotaxonomist. If you like designs and microscopy, you would probably find plant structure interesting. If microscopic organisms appeal to you, you should look into microbiology, phycology, or mycology. If you are artistic, ornamental horticulture and landscape design might be right up your alley. If you worry about feeding the hungry, you should study plant pathology or plant breeding. At some larger universities, you can even study specific types of , each with its own department. These departments include argonomy (field crops), microbiology (microbes like bacteria an ...

... genetic make-up is what makes us unique. It gives us a sense of individuality and distinctiveness. If many people had the same DNA, how would we preserve our diversity and sense of self? Human cloning also raises many ethical and moral issues. Different religious groups regard cloning in different ways, but most agree on one point. Cloning puts the work of God into our own hands. The creation of life then becomes a manufacturing of duplicates instead of a "creative act of God". It is also important to consider the repercussions of cloning on the cloned individual. Numerous psychological problems may arise if a person discovers that he or she was c ...

... is the physical 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, ...

... 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy matrix is washed away, the solution is treated with sulfuric acid and barium chloride. A caustic alkali solution is then added to the remaining clear liquid precipitates the uranium and radium into co ...

... like a German Shepherd. To tell the difference the wolf would have a larger and wider head than any dog. The young ones look like they have smaller heads but they look almost exactly how they would look if they were full grown with small paws. The wolf would move around by walking, running, or in a big pack with it’s family. The pack can have as much as 36 wolves. Each pack always has two head leaders, one male and the other female. The pack may hunt and go as far as 130 to 13,000 sq. km.(50 to5,000 sq. miles)—and will defend all that land from intruders. The wolf would have soft fur over it body to cover it like a jacket to keep it warm during the winter. The wolf ...
