... started to be implemented throughout the world and already a big change is being noticed. Companies are keeping track of all of their important information on web sites, which are restricted to users, unless they have the security code to access them. Thanks to Internet technology, companies and other types of organizations are able to keep all of their information organized and easily accessible with a click of a button. The Internet, how has it changed the world around us? Government, education, business is all wrapping around it. Is this because of all of the information on it, simplicity or is it the quickness, with a simple point and click and ...

... that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground stations. This characteristic of microwaves, the efficiency with which they are concentrated in a narrow beam, is one reason why they can be used in cooking. You can produce a high-powered microwave beam in a small oven, but you can't do the same with radio waves, which are simply too long. Microwaves and their Use The idea of cooking with radiation may seem like a fairly new one, but in fact it reaches back thousands o ...

... by eating grains. The term "gluten-sensitive enteropathy" more correctly defines the clinical pathologic disease caused by an immune-mediated sensitivity to gluten, a protein found in many cereal grains, principally wheat, barley, rye, and to a lesser degree oats. Most nutritionists agree that gluten is not present in rice, white or sweet potatoes, and corn. Over 100 years ago a British physician named Samuel Gee described the "coeliac affection." Dr. Gee observed the syndrome in people of all ages, but especially in children who had chronic diarrhea, weight loss, edema, and a distended abdomen. The led to death unless cured by various diets. Many other physicians ...

... The pressure gradient also plays a role in diffusion. Where this is a pressure gradient there is motion of molecules. The pressure gradient is a difference in pressure between two different points. If the concentration of one side of the membrane is greater than the molecules will travel from the higher to lower concentration. Eventually there will be a dynamic equilibrium and there will be no net movement of molecules from one side to the other. Osmosis is the diffusion of water. Like diffusion, the water moves from a region of higher water potential to a region of lower water potential. Solutions have three different stages that the solutes can ...

... a Megabyte or a million bytes of information could have cost up to $100,000 to store electronically. This same amount of information storage can now cost around ten cents. Because of this expensive storage limitation code written for these older computers was compressed in any way possible. One way to cut down the size of code was to compress dates to a format only six characters long. So instead of April 14 1999 the date would be compressed to 4/14/99. At the time of this programming this seemed to be the best solution to the space saving dilemma. As we come closer to the millennium we see that this style of programming was a great overlook of progra ...

... a new rivalry emerged between the creationists and evolutionists. According to Charles Darwin man began as one of a few species on this new planet striving for survival. However, man was better equipped with certain traits that allowed him to pass through the filter of natural selection. Man was supplied with both physical and intellectual traits that were responsible for allowing him to surmount the other species living beside him. He was able to use his physical traits in order to become the greatest predator, and severely diminish the possibility of become another species prey. His physical traits were also very adaptable and so man was able to change with ...

... English researchers have came the closest by teasing frog body cells to develop into tadpoles. The tadpoles, however, never matured into frogs. The Scottish researchers have failed many times with sheep cells before their success, but the task was perfected and accomplished. Now this accomplishment has made it possible for the cloning of almost any mammal, including humans. To the average person, exactly how the technique works is unclear. Scientist predicted that by making cells dormant and bringing them close to death, something happens to break the chemical locks (barriers) that keep most of the genes inactive. The mammary cell is inserted into an unfert ...

... rain dilemma got worse, the acid rain has put trees in danger and now they are starting to die off. The effects of acid rain on a tree is shown if it has less foliage, yellow spots and produces many cones (Baines, 22). Secondly, acid rain damages the trees through the soil by releasing metals that harm them even further (Lucas, 72). Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds come instead, this process is called a panic shoot (M. 15). Large land areas which used to be covered with forests are now gone, dead or dying (Baines, 21). Around the 1980’s more than half ...

... toward the red end of the spectrum. Hubble attributed this shift to the doppler effect. Hubble saw this and concluded that all galaxies are rushing away from us and the universe is expanding as a whole. Modern equipment has observed and verified this so-called Hubble expansion exists throughout the observable universe. This shows three important things. First there is no significance to the fact that earth seems to be the center of the universal expansion. In any galaxy it would look as if you were standing still and all others were rushing away from you. Second the movement of the universe is not like an explosion. Galaxies are not moved through ...

... . The main chemicals in air pollution that creates are sulfur dioxide and nitrogen oxides. usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild solution of sulfuric acid and nitric acid. Sunlight increases the rate of most of these reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as . Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. In that cycle, water evaporates from the land and sea into the atmosphere. Water in the atmosphere ...
