.... safe, then carry them to water where they hatch into tadpoles. At this stage they have gills, no legs, and a tail. As they mature, their gills and tail disappear, and they develop lungs and legs. This period of tadpole life can be divided into three stages. The first stage, called “ premetamorphosis,� lasts about 50 days (Patent 54). The second stage, in which the hind legs grow, is called “prometamorphosis,� and lasts about 21 days. When the legs are about as long as the body, the third stage, which is called “ metamorphic climax,� and takes place very rapidly, begins. During this last stage, which lasts about a week, m .....

.... the need for in-depth analysis. While it has the highest prevalence of any disease, women experience only 30-50% of the coronary artery disease incidence and mortality of age-matched men (Meyers, 1996). Many feel that this may be due to the protective effect that estrogen has on the blood vessels of females. There may actually be a direct correlation to reduced serum iron levels due to menses. Whereas men " build-up" iron in the blood, women cleanse themselves of iron buildup on the monthly basis. Meyers (1996) also states that oxidation, the process in which an atom increases its positive charges (Miller and Keane, 1992), of low densit .....

.... large dead animals like deer, cattle, and sheep, but will also eat rodents and more rarely, fish. If a meal has been particularly big, they may have to spend hours on the ground or a low branch before they can take off again. s are fastidious birds -- after eating, they clean their heads and necks by rubbing them on grass, rocks, or tree branches. s also bathe frequently and spend hours preening and drying their feathers. s were probably never very numerous in North America. The species once ranged along the entire Pacific Coast from British Columbia to Baja California. Fossils have been found as far east as Texas, Florida, and New York. .....

.... Since the ratio of carbon-12 to carbon-14 in a living organism remains the same as in the environment around them because the organism constantly eats and replenishes it, if it were to die, the ratio would change greatly after many years. It is the difference between this ratio now and the time is died that allows a date for it to be established. Potassium-argon dating, another dating method, is possible due to volcanic ash and rocks found near many fossil sites. Rocks and ash created in this manner contain potassium-40, but no argon. As time passes, the potassium-40 decays into argon-40. In the laboratory, the sample is reheated, an .....

.... conditions, this "pool" drifts southeast towards the coast of South America. This is because, in a normal year, there is upwelling on the western South American coastline, and cold waters of the Pacific rise and push westward. However, during an El Nino year, upwelling is suppressed and as a result, the thermocline is lower than normal. Finally, thermocline rises in the west, making upwelling easier and water colder. Air pressures at sea level in the South Pacific seesaw back and forth between two distinct patterns. In the high index phase, also called "Southern Oscillation", pressure is higher near and to the east of Tahiti than farther .....

.... next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g , this was found to be 88.5grams. Knowing these two numbers, the bouyant force that the water places on the object can be calculated using the formula Fb=W-Wa , Wa=.8673n W=.98n Fb=.1127n Part 2 of this lab consisted of weighing an empty cup, which was 44grams. And then filling another cup up to a certain point the if any more water was added, it would spill out of a little opening in the cup, the water spilled out could be caught in the first cup. This is done so that the water spilled out can be we .....

.... features present at the same time. Modern life is still effected by the different environmental factors and systems that occur worldwide. Each system reaction causes and equal and opposite reaction in an another system. This cause and effect is demonstrated by many of the earth's environmental systems. Deep in the heart of Florida lies a natural resource known as the everglades. This particular system is extremely complex and one that follows the action-reaction principle. Both the correct environmental features, as well as the right rock layers and substrates created the everglades. Geology and the environment created a system that .....

.... effect on the music industry. I will address the issue of piracy later in this report. CDs have become a cost effective industry standard when it comes to storing data. Some terms that you will encounter throughout this report are:  CD-ROM – Compact Disk Read Only Memory, (non recordable CD)  – Recordable Compact Disk  Floppy disk – a square 3 ½ inch disk, with a capacity of 1.4mb  Cartridge – A high capacity form of storage, slightly larger than a floppy disk  Byte - The way that data is measured  MB – megabyte, (1,000 bytes)  Gig – gigabyte, (1,000mb)  Pira .....

.... to change her body image in an attempt to fit in. An Conclusion: It has not yet been pin-pointed what the exact cause of anorexia is. Many factors play a role, including self-esteem. Children need to be showed love and caring in order to gain the appropriate levels of self-esteem.  Anorexia is a big issue in society today. Girls and boys are developing anorexic symptoms as young as age five. While anorexia can be detected in boys, girls, men, and/or women of all ages, “the most common ages of onset [remains] between thirteen and twenty-two.”(Levenkron,1) Anorexia nervosa is an eating disorder .....

.... suffering from the most common, general anxiety disorder . (Harvard, 1). Common are panic attacks (panic disorder), phobias, and general anxiety disorder (GAD). Panic attacks can begin with a feeling of intense terror followed by physical symptoms of anxiety. A panic attack is characterized by unpredictable attacks of severe anxiety with symptoms not related to any particular situation. (Hale, 1886). The person experiencing the attack may not be aware of the cause. Symptoms include four or more of the following: pounding heart, difficulty breathing, dizziness, chest pain, shaking, sweating, choking, nausea, depersonalization, numbness .....
