.... 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 wind is blowing hailstones are at their worst. The most common places to see hail is in Te .....

.... of genes and DNA, the evidence supporting evolution has greatly increased. Charles Darwin was one scientist who helped to increase the evidence supporting evolution. Darwin developed the idea of “natural selection” where living things that reproduced in large numbers and survived became dominant and other living things adapted to survive, or they died. Francis Crick, a scientist, co-discovered DNA which opened new doors to the idea of evolutionism (History). DNA is the pattern by which people are created as individuals. Now Evolutionism is the only .....

.... star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. .....

.... the force of the atmospheric pressure and form the gas (water vapor) that makes up the bubbles you see in the boiling process. The standard temperature at which this occurs is 100 C or 212 F. In the very early stages of heating, you may see some small bubbles even though the water is only warm. This is some air that is dissolved in the cold water and is being expelled by the heating. This is not boiling. As the water nears the boiling point, some areas of the container close to the heat source may be hot enough to cause some boiling in that area which pr .....

.... tons of toxic waste. Toxic wastes, which are dumped in improper sites, can seep into underground water supplies and contaminate huge areas. If the land that is intoxicated supports plant life, most of the plants and trees will die off. If humans occupy the area, it could cause serious illness or death. For example, an area by Niagara Falls (US side) was used during the 1930s by a chemical company to dump its waste. Most of them were hazardous, and the containers that held the chemicals later (after the company had gone out of business) began to leak. The chem .....

.... ("Sclerosis") in the region. Over 5,000 Americans are diagnosed with ALS each year. There is great variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, on average, two to five years. Progression of ALS varies with each individual; therefore, some will live longer--up to 10 years, and about five percent will exceed 12 years. In some cases, the disease seems to plateau. Many patients are able t .....

.... sets of enzymes - DNA helicase enzymes and DNA polymerase enzymes. The DNA helicase enzymes separate the 2 nucleotide strands. The site where the helicase is working and where replication is taking place is known as the DNA fork. The polymerase enzyme helps the nitrogenous base in a given nucleotide to pick up and attach to a complementary base at the 3' end of the DNA template. The 5'-3' strand of template is duplicated in short segments called Okazaki fragments. Ligase is the enzyme that joins the fragments together. The end product of this is an exact copy of .....

.... – Unknown ? Name of Origin – From the Old English word geolo (yellow) ? Symbol Origin – From the Latin word aurum (gold) ? Uses – electronics, jewelry, coins ? Obtained From – crust of the earth, copper ores Atomic and Chemical Properties: In it’s usual state – atomic mass number 197 – gold is stable. However, there are radioactive (unstable) isotopes of mass number 186 to 196 and 198 to 203. Gold normally exhibits a chemical valence of one or three. Gold is the “noblest” of the noble meta .....
