.... the nation. Doctors prescribed antibiotics frequently, often when they were not even needed. According to a 1998 report by the Institute of Medicine, up to fifty percent of antibiotics are prescribed unnecessarily. This blatant overuse of antibiotics had a profound effect on the efficiency of the drugs in the future. The wonder drugs that had been so effective in treating an array of diseases had started to lose the battle against increasingly resistant bacteria, often referred to as superbugs. The problem of is rooted in the overuse of many antibiotics. Doctors used antibiotics to treat countless diseases and some bacte .....

.... may seep into the groundwater feeding your well. The purpose of this project is to explore the subject of groundwater, its place in the water cycle, how it seeps through the ground and how it accumulates in underground pockets called aquifers. The project will also examine the many uses of groundwater in agriculture as well as environmental problems that are presently threatening the quantity and quality of groundwater reserves. THE WATER CYCLE The water cycle is a constant movement of water in the air, in the ground and on the surface of the Earth. It starts when water evaporates from plants, the ground, lakes, rivers and ocean .....

.... all atoms to split apart. Uranium-235 is made up of many protons and few neutrons. Protons naturally repel one another so a nucleus made up of many protons tends to ‘fly apart’ more easily. In addition, uranium makes a good nuclear reactor because it can sustain a series of fission reactions, each time producing more neutrons in chain reaction. Therefore, uranium-235 can produce a steady flow energy output. Uranium can be found in the United States, Canada, and through the world. Uranium in its natural state cannot be used in the fission process. Uranium must go through four steps before it can be transformed into uranium-23 .....

.... concentrating at all. I never knew that a grasshopper had so many complex parts to it. The jaw alone amazed me. I must say that the temperature in the room made those little things stink like a son of a gun. But all in all it was fun and I can honestly say that I actually learned something this year. In conclusion I would just like to state that this project has been a blast, I don’t even mind writing these little papers because it is fun. I'm not just saying this to suck up but I do enjoy Biology not just because I love nature but because you made it fun Mr. Thompson. Thanks for a great year I signed up for Anat .....

.... Park in South Africa. This drastic reduction in range came about as humans and domestic livestock spread into savanna lands. Because live in open areas, they are easily shot by hunters and herders. fur coats are a highly prized possession by poachers, and are worth a lot. Over the last 200 years, over 90% of the world’s lion population has either been shot or killed as result of humans. are also a very popular attraction for zoos and many live in captivity. Diet & Predatorial Behavior Lions are one of the world’s most famous predators. Their preys ranges from insects to giraffes; but they prefer large an .....

.... is only one catch: the federal government prohibited the growth of hemp in 1938. There were also theories that the major energy industries of the late 30s collaborated to ensure a petroleum-based energy market. Regardless of laws, let us consider hypotheticals. Farmers would be practically guaranteed profit if they could grow hemp for biomass. It also would not take long for a measly 6% of the American landmass to start cultivating hemp – enough to replace our economy’s dependence on fossil fuels. As this energy crop grew, it would take CO2 from the air – stabilizing the CO2 content in the atmosphere. The th .....

.... poses a grave threat to humans and the environment. In many places smoke from factories and cars combines with naturally occurring fog to form smog. Smog has been long recognized as a potential cause of death, especially for elderly persons and those with severe respiratory ailments (like asthma). Air pollution originally resulted from large-scale use of heating fuels (like coal and wood). Water Pollution Since the beginning of civilization, water has been used to carry away waste. Rivers, streams, canals, lakes, and oceans are currently used as wastebaskets for every kind of pollution man could create. Water has the .....

.... adds value to conventional marketplace transactions, making the Internet a preferred venue for business? Will markets of the future be substantially more efficient, to the extent of being "friction-free?" Or will a new regime of dominant players arise to eliminate competitors and create "winner-take-all" marketplaces? As electronic commerce spreads internationally, an equally profound issue is the fate of national sovereignty. Economic globalization, particularly of capital markets, is altering the traditional prerogatives of nation-states to control what can take place within their territorial borders. National governments are f .....

.... it showed that 90 percent of all UFO sightings could be easily explained. Most of the sightings turned out to be celestial objects, such as stars or bright planets like Venus, or atmospheric events such as auroras or meteors falling through the atmosphere. Many other sightings turned out to be objects such as weather balloons, satellites, aircraft lights, or formations of birds. Often these sightings were accompanied by unusual weather conditions. Only 5.6 percent of these cases were not explained. Testimonies by people are often very inaccurate and dramatized. People have the tendency to explain everything they see, .....

.... it is stressed that, whatever potential uses it may be put to at some future stage, the technique raises a long string of ethical problems. In addition, it may be feared that within a number of years the development and application of animal techniques will lead to the testing, development and application of human . Though this notion seems very unlikely to occur within the span of the next few years, but the possibility does exist, that the techniques which are currently being used to clone animals may also be used to clone humans one day. There are numerous risks and concerns in regards to . oversteps a limit that man shoul .....
