... a homogenous mixture of two or more substances in a single physical state. Solutions are all around you. All solutions share several important properties. The particles in a solution are very small. In fact, they are atoms, molecules, or ions, which is why you cannot see them. The particles in a solution are evenly disturbed, or intermingled informally on a molecular level. A small sample of one part of a solution. The particles in a solution will not separate no matter how long the solution is allowed to stand under constant conditions. In a solution, one substance is usually considered to be dissolved, or ...

... and radiation and other damage found in vegetation. The 50-page review, being released today, asserts that the scientific community might learn something worthwhile if it can overcome the fear of ridicule associated with the topic and get some funding for targeted research to try to explain these occurrences. "It may be valuable to carefully evaluate UFO reports to extract information about unusual phenomena currently unknown to science," the report stated, adding that such research could also improve understanding of, and in some cases debunk, supposed UFO events. For example, Earth science researchers have ev ...

... on at 55:53:18 ground elapsed time (GET). About 2 seconds after energizing the fan circuit, a short was indicated in the current from fuel cell 3, which was supplying power to cryogenic oxygen tank 2 fans. Within several additional seconds, two other shorted conditions occurred. Electrical shorts in the fan circuit ignited the wire insulation, causing temperature and pressure to increase within cryogenic oxygen tank 2. When pressure reached the cryogenic oxygen tank 2 relief valve full-flow conditions of 1008 psi, the pressure began decreasing for about 9 seconds, at which time the relief valve probably re ...

... been given credit to an English Physicist, Robert Hook (1635-1703), when he looked at a thin slice of cork under powerful hand lens. Hook discovered a large number of cells. Rudolf Virchow (1821-1902) propounded this idea, that the cell is a basic structure and functional unit for all living organisms. A cell can be a wide range of shapes and sizes, although most cells are microscopic. Inside a cell membrane, a nucleus can be seen. The nucleus is the control center of the cell. Between the nucleus and the membrane, there is a polysaccharide matrix called the cytoplasm, where organelles can be found. The org ...

... do not realize the seriousness of this problem. To better understand the importance of the rainforest, one must be knowledgeable about what a rainforest actually is. The two main types of rainforests are temperate and tropical. Tropical rainforests are located in Latin and South America, Africa, Southeast Asia, and other areas in which temperatures stay above 80 degrees Fahrenheit year round. They can be found in 85 countries all over the world, however, 90 percent of them are concentrated into fifteen countries, each containing over ten million hectares. Tropical rainforests receive 160 to 400 inches of ...

... a national wildlife refuge about twenty-seven miles off San Francisco, is a common feeding ground for the great white. The coastal waters along central California, especially around the Ano Nuevo State Reserve and along the Marin Headlands, are another common area for white sharks. In the summer the sharks move to the coasts of Oregon and occasionally the Gulf of Alaska, and in the fall, they turn south and move along the offshore islands. They are also found in great numbers in the Australian waters. The great white is a very agile killer that hunts mostly anything in the ocean. The ...

... Changing life to service us is not morally wrong. It is not inhuman either. Of course, if you believe using animals for scientific research is morally wrong that's your belief, I am stating that genetically enhancing them to be better research specimens is not unethical. My reason behind this is that we don't just do research in order to infect and kill off the mice, we do it so one day we will have a cure for cancer and can save hundreds of thousands of human lives. Of course if you value the life of a mouse over a human then you would see differently. Some fear that this science is too powerful, granted we shou ...

... cent (Myers, 1994) of the world's commercial energy is derived from oil, coal and gas. Although it has been observed that the growth of energy consumption is closely correlated with the increases in gross national product thus our economic development, the major sources of energy (that is fossil fuels) are 'stock resources'. Fossil fuels are consumed by use and the current consumption patterns are non-sustainable. It is recognised that energy conservation and the development of renewable energy sources will be needed to sustain economic growth. The quantity of ultimately recoverable fossil fuels is limited by geolog ...

... Cold sores are common in young children who acquire them from being exposed to active cold sores of adults and other children. This form of is annoying but harmless in both children and adult, but is however very harmful to a newborn. It can sometimes be difficult to distinguish whether or not someone has been exposed to the other form of , genital . This is because there are very often no symptoms that go along with the virus. This is not always the case though and when symptoms do occur they are often seen as a cluster of blister sores, usually on the vagina, vulva, cervix, penis, or anus. For genital , ...

... of the century, next to the Kennedy Assassination (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 unexpla ...
