.... to be old stream channels. This implies that there could have been liquid water on the surface. The surface of Mars is varied greatly between north and south. This has been largely attributed to volcanism and erosion. Mars is similar to our moon in the southern hemisphere. This region is referred to as the “Highlands” of Mars. The area is pitted with numerous craters that reach between one to four km above the datum. Ejecta from the impact scatter around the crater making a rim like structure. The northern hemisphere is very low compared to the southern hemisphere. In the north the ground level rarely reaches above one km below the datum. This st ....

.... has been impossible until now, with Genetic-Engineering. I doubt that there have been any real disadvantages with this technology, since it works to heal the patient, but we really can't predict what kind of medical misfits there will be in the future, using this life-saving technology to their own personal, perhaps evil, advantages. Dealing with politics, Bioengineering has opened a whole new door pertaining to the military, whose use of it may create an ultimate destruction. The alterance of nature is un-natural, and creates an unbalancement in life. When we use this technology towards the wrong side, we may all be burned. You see, Biotechnology has the ability to altar ....

.... the same temperature until it has become completely solid, because heat is given off by the substance in its change from the liquid to the solid state. Hence, the freezing point or melting point of a pure substance may also be defined as the temperature at which freezing or melting continues once it has commenced. All solids melt when heated to their melting points, but most liquids can remain liquid even though cooled below their freezing points. A liquid may remain in this supercooled state for some time. This phenomenon is explained by molecular theory, which conceives the molecules of a solid as being well ordered and the molecules of a liquid as being disordered. To sol ....

.... Feyman, and Robert Oppenheimer, each with their own ideas of what it would take to construct such a weapon. From left to right: Neils Borh, Robert Oppenheimer, Richard Feyman, Enrico Fermi The object of the project was to produce a practical military weapon in the form of a bomb in which the energy would be released by a fast neutron chain reaction in one or more of the materials known to show nuclear fission. That goal was to be completed in 1945 after the U.S.A. spent over 6.7 Billion Dollars on the test bomb named the "Trinity". I t was dropped on Alagormado in Texas on July 16th 1945. When Albert Einstein heard about the "Trinity" he called the president directly and ....

.... towards hurricanes. Furthermore, I am going to look at the economical affects that hurricanes have on the United States. There are many reasons why I chose to use this variable. The main reason is I couldn't think of another topic that fit into e veryone's lives and had an effect on everyone. The hurricane year is broken up into two seasons. They are referred to as early season and late season. The early season starts June first and runs to September 10. The late season starts on September 10 and runs to the end of November. The date of September 10 is the midway point between the two seasons. This is the date that separates early season from late season. This leads me to wh ....

.... check the balance and record the mass of the remaining mixture in the vial. In the laboratory hood, dissolve the copper with ~ 3 mL of nitric acid. Allow the beaker to remain under the hood until the fumes cease. The remaining solution should be blue. Bring the beaker back to the lab station and add ~ 10 mL of distilled water. Stir the mixture, all the while adding ~ 8 mL of 6M of NaOH to the beaker. Check with litmus paper to ensure that it is slightly basic. Fill the beaker with up to 100 mL mark with distilled water. Heat the solution and allow it to boil for 5 minutes. Prepare a squirt bottle with hot water. Filter the solution and rinse the beaker with ....

.... (Hammen 62). What is this mystery that the government has been hiding for 50 years? The answer is Area 51. Area 51 was built in the 1950's by the CIA as a top secret area of defense. It was the testing grounds for such war planes as the Aurora Project, SK-71 Blackbird, and the F-117a Stealth fighter spy plane (Misage 15). According to many Americans, these are not the only flying machinery which exists in Area 51. On July 7, 1947, two ranchers in Roswell, New Mexico, observed something that would be the beginning of what might be one of mankind's most unexplained phenomenons in history. According to these ranchers, (who asked to be anonymous) a flying object came ou ....

.... hormone imbalance. While Dr. Harry Klinefelter accurately described this condition in 1942, it was not until 1956 that other researchers reported that many boys with this description had 47 chromosomes in each cell of their bodies instead of the usual number of 46. This extra sex (X) chromosome causes the distinctive make-up of these boys. All men have one X chromosome and one Y chromosome, but sometimes a variation will result in a male with an extra X. This is and is often written as 47,XXY. There are other, less common variations such as 48,XXYY; 48,XXXY; 49,XXXXY; and XY/XXY mosaic. All of these are considered variants. The major effect of the extra X chromosome in b ....
