... This source is renewable energy and is already readily available. The increased use of renewable energy, mainly wind and solar energy, and reduction of dependence on oil is the best way to solve our current energy dilemma. For the past fifty years, fossil fuels have been the main source of energy in the U.S. They are a great source of power, but unfortunately they also have many setbacks. The finite reserves of fossil fuels are being depleted at a rate one hundred thousand times faster than they are being formed. As supplies decrease we become more and more dependent on the Middle Eastern countries for our supplies of oil, recently, fifty-two percent of imp ...

... dense cloud of gas and dust. In 1965, A. Poveda stated, “That new stars are likely to be obscured by this envelope of gas and dust (1).” In 1967, Davidson and Harwit agreed with Poveda and then termed this occurrence, the “ cocoon nebula” (1). Other authors have referred to this occurrence as, a “ placental nebula” (1), noting that it sustains the growth of planetary bodies. For a long time, even before there was the term cocoon nebula, planetary scientists knew that a cocoon nebula had surrounded the sun, long ago, in order for our solar system to form and take on their currents motions (1). In 1755, a German, named Immanuel Kant, reasoned that “g ...

... environment. They produce much of the electricity that fuels our economic growth. They power new industrial technologies that keep our economy growing and improve our global competitiveness. They cut America's demand for imported oil by nearly 100 million barrels a year—reducing our dependence on foreign oil suppliers and cutting our trade deficit. The future looks even better. Advanced-design nuclear power plants are now being developed—quicker and less costly to build, better performing, and even safer than today's plants. These plants will supply our children's and grandchildren's electricity—while helping to protect their environment ...

... air condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amount ...

... as an important method of science. The first recorded action of vivisection was the study of body humors by Erasistratus in Alexandria during the third century (1:3). Later, in A.D. 129-200, the physician, Galen, used five pigs to investigate the effects of several nerves (1:4). He is considered to be the founder of experimental physiology. During the Renaissance Era, Andreas Vesalius conducted experiments on monkeys, swine, and goats (1:3). By the late eighteenth century, the methods of scientific discovery were changer to experimentation of live animals by two French physiologists, Claude Bernard and Francious Magnedie. They revolutionized methods of scientifi ...

... you may have unprotected sex or share needles or syringes with. AIDS and HIV are two different viruses, but HIV well eventually turn into AIDS. About half the people with HIV develop AIDS within 10 years, but between infection with HIV, the onset for AIDS can vary greatly. The severity of the HIV related illness or illnesses will differ from person to person, according many factors but mostly to the overall health of the individual. The new advances in technology are helping postpone the advancement of the disease. Lets start at the beginning. First, lets learn what AIDS is. AIDS is an acquired defect in your immune system. The passing of any bodily flui ...

... vegetation zones, the Tundra is located in Arctic climate areas. Temperature The Tundra suffers a very harsh climate. Because of this fact most of the area remains barren save for a few shrubs and lichens. It's winters last from 8-10 months and the summers are cool and short. Also due to the fact that much of it's territory is located within the northern pole a lot of the Tundra receives alternating 6 month periods of light and dark. This is also the reason why the Tundra receives cold weather; at it's degree of latitude the suns rays end up hitting the region obliquely, thus causing less solar heat. Here are the temperatures of the Tundra in general: Average ...

... predatory nature. CLASSES Many questions have risen regarding the praying mantis. Such questions include how many different species there are in the animal kingdom. Estimates range from 1500 to 2200 different mantid species WORLDWIDE. The most common figure given, though, is about 1800. The ways the Mantid's are classified in the Animal Kingdom. There is agreement that the collection of mantid species make up the Mantidae family of insects. The Mantidae family, in turn, is part of the order/suborder Mantodea that includes a variety of mantid-like species. But the existing literature does not reflect a clear consensus about what insect order Mantodea belong ...

... In 1980, she tried being regressed under hypnosis by Dr. Leo Sprinkle. During the sessions conducted by Dr. Sprinkle, she was unable to recall what her captors looked like, but did remember that technological implants had been made, including audio-visual implants. The UFO entities can see through her eyes and hear through her ears. She is aware of the continuous presence of what she calls her "live-in companion," who answers to the name of Hweig. Mrs. Kannenberg realizes that Hweig would be explained away by conventional scientists in terms of split personality or some other form of mental abberation. Although she does not agree ...

... society’s failure to recognize the severity of a potential environmental disaster as a result of . It is important that society treat human-induced as a serious global-scale environmental threat. The overwhelming majority of scientific experts believe human-induced climate change is inevitable. The question is not whether climate will change in response to human activities, but rather where (regional pattern), when (the rate of change) and by how much (magnitude). (17,18). Alarming information and trends are leading the scientific community in this same belief. The concept of is predicting detrimental events for the future. The most prevalent issue of is t ...
