... of earth. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects from the winds that ...

... and deoxyribose, a component of deoxyribonucleic acid. Among the most important aldohexoses are glucose, mannose, and galactose; fructose is a ketohexose. Several derivatives of are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a monosaccharide, include sorbitol (glucitol) from glucose and mannitol from mannose; both are used as sweetening agents. Glycosides derived from are widespread in nature, especially in plants. Amino sugars (i.e., sugars in which one or two hydroxyl groups are replaced with an amino group, -NH2) occur as components of glycol ...

... experiment. When thinking about hydroponics one must think about the applications of hydroponics. Not only dose hydroponics produce bigger, better, and more healthier plants than the traditional dirt, but it can also be greatly beneficial on things like submarines, space stations, off-shore oil rigs, or any where else where dirt is hard to come by. During this experiment we'll be looking for which plant life well do best with hydroponics, by measuring which plant has grown the highest or bushiest. We also well be looking for green and healthy looking leaves on the plants. We have no idea what the results might be, so this should be an exciting experiment. ...

... to the US Commerce Secretary William Daley, who is in charge of fishery management. They are requesting that the water be re-opened for fishing. Problems for concern to many, are that all the regeneration that has occurred due to the closure of these waters will all be for nothing if re-opened because the same problem will happen again. Another concern is that the equipment that is used by the fishermen to catch the scallops not only do just that, but they also pick up everything else in their path. This has an impact on all marine life, particularly species such as sponges and barndoor skate which were almost forced to extinction because fishermen can't cont ...

... near the ground in cold weather. The biggest hailstone ever found was discovered in Coffeyville, a small town in southeast Kansas. This hailstone weighed 1.671 pounds and was 17.5 inches in circumference. The largest stone previously on record was almost the same size. It was found in Potter, Nebraska on July 6, 1928. The hailstone had a circumference of 17 inches and weighed 1.51 pounds (Dennis 54). Hail can be extremely dangerous. It can break windows, damage roofs, dent cars, injure and even kill people! Crops are greatly affected. Hail causes around two hundred million dollars in damage a year. That's a lot of money. When the win ...

... 357C,and has a gravity of 13.5. The atomic weight of mercury is 200.59. Mercury comes in its pure form or combined with silver in small amounts. It is mostly found in the form of the sulfide. Mercury has many uses and is a very important element. A major use of mercury is in electrical equipment such as fluorescent lamps, and mercury batteries. Mercury is used in thermometers because the change in volume for each degree of rise or fall in temperature is the same. The use of mercury in the thermometer instead of alcohol was done by Gabriel Daniel Fahrenheit in 1714. It was also used in vacuum pumps, barometers, and electric rectifiers and switches. Me ...

... particles emitted per second by a gram of radium. He was also able to confirm that alpha particles cause a faint but discrete flash when striking luminescent zinc sulfide screen. These great accomplishments are all overshadowed by Rutherford's famous Gold Foil experiment which revolutionized the atomic model. This experiment was Rutherford's most notable achievement. It not only disproved Thomson's atomic model but also paved the way for such discoveries as the atomic bomb and nuclear power. The atomic model he concluded after the findings of his Gold Foil experiment have yet to be disproven. The following paragraphs will explain the significance of the Go ...

... are hard but in time they can bend or fold producing Folded mountains. The Alps formed as the Eurasian plate pushed against the African plate. Other examples of folded mountains are the Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are formed when one plate pushes or pulls away from another plate. In the Earth, hot currents of magma or molten rock may well up and crack the weakened crust above. As the crust cracks, blocks of rock rise or fall forming Fault-block mountains. Examples of these mountains are the Sierra Nevada in California and the Grand Tetons in Wyoming. Dome mountains are formed by the same kind of molten rock th ...

... constructed inventions in this world is ethical, which means that these inventions conform to one’s moral standards (Epstein 5). Others argue that such inventions as human clones, which are genetically constructed humans, and other genetically created figures, are wrong and should be stopped (Epstein 5). Overwhelming textual evidence proves that genetic engineering is not beneficial to society. Accordingly, genetic engineering is unethical and therefore should be stopped. One reason why genetic engineering should cease is because genetic engineering disrupts society’s moral values and causes society to act out in destructive ways. An online sur ...

... that may have fallen victim to the hurricane's epic floodwaters. Workers hack and chip at the mud with shovels and pickaxes, and an endless procession of shopowners scurry between their gutted businesses and the river in a desperate attempt to wash and salvage their goods. A muddy valley runs past the Central Prison, where some of the incarcerated swam to freedom as Mitch's floodwaters rose and propelled them over the walls. Hundreds of homes, streets, and businesses were washed away, and those that remained standing found themselves anchored beneath several feet of mud and debris. In some places, the stench is overpowering. The smell from interm ...
