... gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of nature's evolu ...

... to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests. These human practices have already changed the chemical make up of the atmosphere. Between the pre-industrial times and today, we have seen the concentration o ...

... sent mass outward in every direction), but I wouldn’t think of it as the origin of the universe. I mean, in my mind, something had to be there to cause this super mass. Was the universe contracting until it formed this huge mass? I believe that we may never know how the universe came about, rather have some idea as to what came directly before it’s current state as well as before that and so on. We could come up with ideas until we die, and someone would just continue in our footsteps. I do have one idea as to how this super mass which is the being behind the big bang theory came to be one mass. Scientists as well as philosophers and just about anyone you talk to ca ...

... shallow tunnles under flat stones or logs. Burrows found in east Texas were about 2.5 cm round, from 25 cm to 1.5 m long, and not more than 20 cm below the surface. Each burrow has a large area at the end for the nest which was composed of shredded grass. These nests were used for young or as a resting place for groups of adult shrews. Compared to most types of shrews, the least shrew is sociable, and several may be kept together in captivity without conflict. They sleep together and help eachother to some degree in digging tunnels and finding food. One nest found in December in Texas contained a dozen shrews that seemed to be staying there for the winter; another ...

... fat diets. My stepfather had coronary heart disease. He talked about it freely before he passed away. Over the course of 10 years he had two triple bypass surgeries.

Family activities didn’t change much. The only noticeable difference was the fact that he quit smoking. “Each year, 900,000 people in the ...

... tree, some tea leaves fell into Sheng's pot of boiling water. After drinking some tea, he discovered its miraculous powers and immediately placed tea on his list of medicinal herbs. John Blofeld, in Chinese Art of Tea, writes that ˇ§it can be confidently stated that tea was known in the three kingdoms epoch (AD 222-277).ˇ¨ More importantly, however, ˇ§tea [was] originally drunk for its medicinal properties.ˇ¨ (Blofeld 4) Evans links the early popularity of tea to Taoist religious practices during the Qin Dynasty (201 ˇV 207 B.C.). ˇ§Taoists in particular became obsessed by long life and an Elixir of Life became a Taoist ideal.

... oxide being from six to ten seconds, it is not surprising that it has not been until recently that it was discovered in the body. The compound is quickly converted into nitrates and nitrites by oxygen and water. Yet even its short-lived life, it has found many functions within the body. Nitric oxide enables white blood cells to kill tumor cells and bacteria, and it allows neurotransmitters to dilate blood vessels. It also serves as a messenger for neurons, like a neurotransmitter. The compound is also accountable for penile erections. Further experiments may lead to its use in memory research and for the treatment of certain neurodegenerative disorders. On ...

... young and old forests says how this is in fact not true. Loggers have said that new trees pull the carbon dioxide better than old trees, and this may seem true, but it is not. There is one point being overlooked from all of this. The older, larger trees can store much, much more carbon dioxide than a new tree could. By cutting and burning these magnificent seasoned trees, the CO2 is being released back into the atmosphere. These releases of carbon dioxide add up in our surroundings, only to intensify Global Warming. Although this shows what happens when one burns and cuts down old forests, one must still plant new trees for long term plans, not letting them g ...
