... Cumulonimbus clouds. High clouds are made of ice crystals due to the cold air in the upper sky. The base of a high cloud above the surface can be anywhere from 6000-18000m in the tropics to 3000-8000m in the polar regions. Cirrus clouds are the most common of the High Cloud group. They are composed entirely of ice and consist of long, thin, wispy streamers. They are commonly known as "mare's tails" because of their appearance. Cirrus clouds are usually white and predict fair weather. Cirrostratus clouds, belonging to the high cloud group, are sheet like thin clouds that usually cover the entire sky. The sun or moon can shine through Cirrostratus clouds. Sometimes, ...

... decades the problems of atmospheric change have been gravely advanced by pollution resulting from human activities. These environmental changes pose a real threat to the lives of people and wild life.It is vital to all of us that we fully understand the complex relationship between the atmosphere and the earth. The earth is getting warmer. the changes are small, so far, but they are expected to grow and speed up. Within the next 50 to 100 years, the earth will continue to heat up hotter than it has been in the past million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crop ...

... prevents hypoglycemia (low blood sugar), by binding adrenergic receptors in the hormone releasing cells of the pancreas. Epinephrine is called the “fight” or “flight” hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids control the overall body fluid. Mineralocorticoid ...

... of the zodiac. The orgins of the names given to each sign extend into the most remote regions of antiquity. Terrestrial animal gods, whether real or imagined , were one day projected onto the constellations which, in the Chaldean imagination, they resembled. This celestial menagerie has furthermore given the zodiac its name, for in greek, it means "route of animals." The sun enters the first zodiacal sign, Aries , and then continues its path through the remaining eleven signs. The twelve signs of the zodiac are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The moon and the planets pass through ...

... sulfide minerals, oxygen, and water. Biological activity and reactions is what is responsible for the production of ARD. These reactions make low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE DRAINAGE Within the mining process there are several sources that cause ARD. No matter what activities occur, ARD usually occurs when certain conditions are met. These conditions are the factors that limit or accelerate the release of ARD. The initial release of ...

... is a curve of colored light which is seen in the sky. Rainbows can be seen in moonlight or in artificial light. They are caused by the sun shining through tiny drops of water in the air. A rainbow's brightness depends on how large the drops are. The larger the drops are the brighter the rainbow will be. Many people think that a rainbow is only made of six colors, but it is really make of seven. The colors in order are red, orange, yellow, green, blue, indigo, and violet. A primary rainbow is a rainbow with red on the outside and violet on the inside. The largest rainbow visible to observers on land is a semicircle, but many times you can only see half o ...

... muscular lining churns the food causing mechanical breakdown to take place. In the stomach lining, the pyloric glands secrete mucus that forms a mucus lining. Also in the stomach lining, are epithelial cells and the gastric glands. The gastric glands secrete gastric juices. Hydrochloric acid is released which deactivates the salivary amylase, in turn stopping the chemical breakdown of starch into maltose. Pepsinogen, which is an inactive enzyme, will change to pepsin, an active enzyme, when mixed with hydrochloric acid. Pepsin breaks down proteins, forming chains of amino acids called polypeptides. Chyme, a mixture of churned food, mucus, and digestive enzym ...

... a flat or even depressed area at the base of the nose, a protruding jaw, and sometimes the teeth are crowded and the upper and lower teeth may be badly aligned. An adult with usually has an exaggerated forward curve to the lower spine. The legs of a person with almost always become bowed and the elbows often cannot be straightened completely. Sometimes the person has limited twisting ability at the elbows. The hands are short, and the feet are short and flat. Another sign is double jointedness, caused by loose ligaments in some joints. Achondroplastic children can flex their finger, wrist, hip, and knee joints to an extreme degree because of this. Th ...

... The total number of opportunities was fifteen a day. Every time the action occurred, the subject was immediately picked up and placed back inside the house. Day's five through eight were designed to truly concentrate on implementing the developed program with the same number of opportunities to escape as the previous four days. RESULTS It was determined that the subject would almost always attempt to escape from the house when it was given the opportunity during the first four days. As the days progressed, it's total number of escapes decreased. This could be attributed to the fact that every time it found it's way outside, it was immediately picked up ...

... been observed that the growth of energy consumption is closely correlated with the increases in gross national product thus our economic development, the major sources of energy (that is fossil fuels) are 'stock resources'. Fossil fuels are consumed by use and the current consumption patterns are non-sustainable. It is recognised that energy conservation and the development of renewable energy sources will be needed to sustain economic growth. The quantity of ultimately recoverable fossil fuels is limited by geology and remains a matter of suspicion, but the view of the 1970s that scarcity was imminent is still popular. It is the 1973 Oil Crisis marked the trans ...
