.... O3. O3 is ozone. So when ozone is formed, harmful rays from the sun are absorbed. The O3 molecule is very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being created and destroyed in the atmosphere. The amount of ozone in the atmosphere is based on these reactions. There are many factors that influence the amount of reactions like season, lat .....

.... a tick and a tkhirrr, which are alarm notes. There is also a location call, known as a "whinny", made up of a dozen or more tchicks all strung together. Scientific Names The downy woodpecker's scientific name is Picoides pubescens. There are also six particular downies with six particular scientific names all from different regions of the United States and southern Canada which I have listed below: southern downy / Dryobates pubescens Gairdner's woodpecker / Gairdneri pubescens Batchelder's woodpecker / Leucurus pubescens northern downy / Medianus pubescens Nelson's downy / Nelsoni pubescens willow woodpecker / Turati pubescens .....

.... that once had eight times as much matter as our sun and was 1,000,000 miles across, becomes a sphere only ten to fifteen miles across. As the star collapses, very small particles (called neutrinos) escape into space. After the star becomes a very small sphere, it explodes like a giant nuclear bomb and becomes a billion times as bright as our own sun. All kinds of matter and radiation are blasted into space. This matter and radiation travels through space at nearly the speed of light (186,000 miles per second) Now, if one of these supernovae were to occur within about 130 light years of Earth, some scientists feel that life on earth would be .....

.... Until 1955 the only sources of diamond were found in deposits of volcanic origin. Since then scientists have found ways to make diamond from graphite and other synthetic materials. Diamonds of true gem quality are not made in this way (Beggott 3-4). Graphite is another form of carbon. It occurs as a mineral in nature, but it can be made artificially from amorphous carbon. One of the main uses for graphite is for its lubricating qualities. Another is for the "lead" in pencils. Graphite is used as a heat resistant material and an electricity conductor. It is also used in nuclear reactors as a lubricator (Kinoshita 119-127). Amorp .....

.... on April 12, 1981. It was a test flight flown without payload in the orbiter's cargo bay. The fifth space shuttle flight was the first operational mission; the astronauts in the Columbia deployed two commercial communications satellites from November 11 to 16, 1982. Later memorable flights included the seventh, whose crew included the first U.S. woman astronaut, Sally K. Ride; the ninth mission, November 28-December 8, 1983, which carried the first of the European Space Agency's Spacelabs; the 11th mission, April 7-13, 1984, during which a satellite was retrieved, repaired, and redeployed; and the 14th mission, November 8-14, 1984, when two expensiv .....

.... U.S. at an alarming pace. It is called affluenza it is very contagious and growing at frightening rates. In 1997, an amazing 1.1 million debt plagued spenders filed for personal bankruptcy that was a 28.6% increase from '96. Economists predict another 1.6 million to file by the end of this fiscal year, (Shop 'til We Drop [STWD], 1997). These are two vivid examples of the amazing rate at which affluenza is growing. These numbers are occurring Causes & Cures despite the strong economy and perhaps because of it. With the economy in the U.S. going so well credit card companies are issuing more credit. Consumers are then using their new found cr .....

The families have home territories that they rarely leave. families may co-operate to catch large animals. es chase their prey. They wear them out in a long chase because they arenÕt very fast runners. Large animals are chased until the es can catch them or until the weaker ones drop back. es donÕt always get their prey, however kangaroos can lean back on their tails and kick hard enough to rip open a Õs stomach. The gestation period of the is about 63 days, and the litters average about .....

.... humans can be cured of diseases that are currently life threatening. Where cells can be "cultivated in lab dishes" to help preserve human life. In the following paragraphs, he goes on to write about the "hasty legislation" that could possibly have negative long-term effects on the future of because of the bad wording going into some of the laws. Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nash points out that even though the possibility is there, the people who could grow full human clones "aren't going to be doing it." Nash recognizes that by individual cells for th .....

.... technicians researched the avenues of fiber optics. Fiber optics can be seen in telephone systems, in the military, in cars, in medicine, and in many other fields of study. For all industries and professions, "Fiber optics allow huge amounts of voice, data and video imagery to be transmitted instantaneously, allowing for photographic-quality images, interactive video conferencing and other business multimedia uses" (Inman News Features 1). It's becoming possible to transmit audio, video and data signals over great distances using these fibers of pure glass or plastic. Today, fiber optic technology has almost become a necessity in everyday business. B .....

.... and winter, when there are fewer hours of daylight. In dysthymia (pronounced dis-THI-mee-uh), people feel depressed, have low self-esteem, and concentrate poorly most of the time—often for a period of years—but their symptoms are milder than in major depression. Some people with dysthymia experience occasional episodes of major depression. Mental health professionals use the term clinical depression to refer to any of the above forms of depression. Surveys indicate that people commonly view depression as a sign of personal weakness, but psychiatrists and psychologists view it as a real illness. In the United States, the National Institute of Ment .....
