.... however, that the two names referred to the same body. Since Mercury is a smaller planet, extremely close to the sun, and has no substantial atmosphere, it has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin. On the side facing away from the Sun, or the night side, the temperature drops to -183 degrees Celsius. Scientists have detected a magnetic field surrounding Mercury, though it is not as strong as the field around the Earth. Scientists theorize that Mercury's field is due t .....

.... safety. Life and death situations could arise as hospital systems such as, life support and machines used to monitor a patients vital signs are among the systems at risk. Australian hospitals believe that as many as 60% of their machines may not work properly when the date rolls over. Local testing has identified the ultrasound machines and central monitors which have exhibited year 2000 failures. There could be significant threats to personal safety, for example if an ultrasound wrongly calculated the size of a faetus or administered radiation therapy incorrectly. Also people with heart pace makers could face the possibility of them failing. Bank a .....

.... much of which has been gained with Marks & Spencers plc. The majority of these employees are based in the Chester head office, and systems are developed ‘in-house’. IS projects under development include the introduction of Individual Savings Accounts, with other likely future projects including telephone banking, credit cards, and auto/property insurance. The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry r .....

.... turns to a liquid. When the temperature reaches approximately 90o Celsius, stop heating. 6. Observe the change in temperature from 90o to 70o Celsius, recording the temperature at regular intervals, preferably 15 seconds. This data will be used to make a chart later. 7. Once the temperature has fallen to 70o, melt the naphthalene which is now frozen to remove the thermometer. Properly dispose of the naphthalene liquid as instructed by the teacher. IV. Data Time Elapsed Temperature of Naphthalene Time Temperature Initial (0:00) 100oC 7:00 78.5oC 0:30 97.5oC 7:15 78.3oC 1:00 93.0oC 7:30 78.3oC 1:30 89.5oC .....

.... biochemist, molecular biologist, or chemotaxonomist. If you like designs and microscopy, you would probably find plant structure interesting. If microscopic organisms appeal to you, you should look into microbiology, phycology, or mycology. If you are artistic, ornamental horticulture and landscape design might be right up your alley. If you worry about feeding the hungry, you should study plant pathology or plant breeding. At some larger universities, you can even study specific types of , each with its own department. These departments include argonomy (field crops), microbiology (microbes like bacteria and fungi), horticulture (fruits, o .....

.... elements, Einsteinium (Es), Mendelevium (Md), and Nobelium (No). Plutonium was Seaborg’s first discovery. Its name came from Pluto, the planet after Neptune for which Neptunium was named. In 1940, at the University of California at Berkeley, he bombarded a sample of Uranium with deuterons, the nuclei in atoms of deuterium, transmuting it into plutonium. Shortly after, Seaborg was able to isolate plutonium 239, an isotope used in atomic bombs. Plutonium is a highly dangerous and poisonous element because it rapidly gives off radiation in the form of alpha particles. Alpha particles, which are identical to the nucleus of a helium atom, co .....

.... lost somewhere in the Mount Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the first UFO sighting in history, Kenn .....

.... and the storage of animal sperm and embryos for use in animal husbandry or artificial insemination. An understanding of crop origins and variations is necessary in assembling genetic diversity in plant crops. In certain geographical areas there has existed a rich source of variability in crop plants but the encroachment of civilization has reduced the natural variability inherent in primitive plant forms and related species of crop plants. Agricultural process, as a result of new breeding programs, has reduced rather than increased crop variability as improved cultivars, or varieties, are planted in wider and wider areas and old cultivars, w .....

.... unzipped by an enzyme called polymerase. From one of these single strands of a DNA molecule, a mRNA molecule is built. This is accomplished by an enzyme which travels along a portion of DNA between two exons and attaches the opposing base pairs to the backbone of the mRNA (a structure composed of phosphates and ribose). The nitrogen bases of this new molecule are identical to that of the opposite side of the original DNA molecule except that the thymine has been replaced with uracil. The formation of this molecule allows for the construction of proteins in the ribosome without risking the DNA in the cytoplasm. The mRNA travels through the cell to a .....

.... theory met controversy until 1954, when British geophysicists seeking to explain the phenomenon of polar wandering revived it. Since then, the modern theory of Plate Tectonics has evolved from and replaced Wegener's original thesis. Plate Tectonics is the theory that deals with the structure, history, and dynamics of the earth's crust. The earth's crust is formed of 13 continental plates. The boundaries of the zones are where tectonic activities occur, and where earthquakes and volcanic eruptions tend to happen. The plate tectonics theory was thought up in the 1960s and 1970s, with ideas taken from Wegener’s earlier thoughts. Earlier, Wege .....
