... divide as would a regular embryo. The embryo was then implanted in a third ewe who only a few months later gave birth to Dolly 1 . Upon news of this, many people began to question the possibility of not only creating genetically identical sheep, but humans as well. There has been much controversy on whether or not the cloning of humans as well as animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers. WHAT ARE THE BENEFITS IN CLONING RESEARCH? There is no doubt that Dr. Wilmut's new discoveries have brought an uproar of excitement between not only the scientific community, but t ...

... ingredient in all preparations (NIH). The more THC contains, the stronger it is. The effect of the drug depends on the amount taken amd the users past experience and emotional state at the time. According to "The National Clearinghouse," (NCH), the effects of are similar to alcohol intoxication. Small amounts can make you relaxed and generally less inhibited. Some users say that it enhances the experiences of music, food and sex. Logical thinking tends to be slowed, but smokers often believe that their minds are flitting from thought to thought with great speed (NIH). Intoxication is more intense during the first hour after smoking, although the dru ...

... to observe, and some to rebut. Scientists, engineers and many local planners see coastal erosion and as a serious issue but previously viewed the concept of sea level rise as a codeword for “retreat,” giving up protective measures for the barrier island communities.There has been polarization in the past between some mayors and public officials who favor public expenditures to hold back the sea and other public officials and some scientists who are skeptical about erosion-fighting programs. There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for r ...

... in crawl spaces, through cracks, openings in floors, and through below grade walls and floors. This is the primary source of elevated radon levels in buildings.(5) Outdoor air contains radon, but it is in extremely low concentrations therefore it is not a health hazard. Some wells contain water that has radon dissolved in it. This can be a hazard if the water is agitated or heated, allowing the gas to escape and elevate the levels that are in the building.(6) Health Risk The Surgeon General's office reports that indoor radon gas is a national health problem. This gas causes thousands of deaths every year.(7) These deaths are a result of lung cancer, whi ...

... react with hydrocarbons in the prescence of sunlight to produce a form of oxygen called o-zone. O-zone(O³) is the chief component of photochemical smog, which is a common form of . Fuel combustion for heating and cooling homes,offices,buildings, and factories contribute significantly to . Electric power plants that burn coal or oil in also releases pollutants into the atmosphere. The major pollutants from these source are nitrogen- oxides, sulfur-oxides, and carbon dioxide. The rapid growth of population and industry, and the increased use of automobiles and airplanes has made a very serious and complicated problem. The air we know today and breathe has ...

... negative charge. Objects with the same # of positive and negative charges are electrically balanced, or neutral. Electric force is observed only when the balance of charge on objects is disturbed. An on an object that causes the object to attract or repel other objects is called static electricity. The adjective static describes something that does not move. Charges on an object are called static electricity to contrast then with the moving charges in an electric current. How can you disturb the balance of charge on objects so they exert electric force? The easiest way is the same way the ancient Greeks did it – by rubbing the 2 objects together. Rubbing neu ...

... four are the main categories: 1. Scalloped hammerhead (Sphyrna lewini)-Pectoral fins are tipped with black this grey shark. The maximum length is about 12 feet. 2. Bonnethead (Spyrna tiburo)-With a head shaped like a shovel the bonnethead rarely grows more than four feet long. This shark is commonly seen inshore. 3. Smooth hammerhead (Sphyrna zygaena)-Bronze with dusky fin tips, it can grow to thirteen feet. 4. Great hammerhead (Sphyrna mokarran)-Attaining a length of a possible 18 feet, this is the largest and most dangerous of all the hammerheads. One of the most interesting things about the hammerheads is the unique shape of their heads. Ever since scien ...

... usually given in terms of atmospheric concentrations or, for gases in terms of parts per million, that is, number of pollutant molecules per million air molecules. Many come from directly identifiable sources; sulfur dioxide, for example, comes from electric power plants burning coal or oil. Others are formed through the action of sunlight on previously emitted reactive materials. For example, ozone, a dangerous pollutant in smog, is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. On the other hand, the discovery in the 1980s that air pollutants such as fluorocarbons are ...

... called photosynthesis. The next stage in the development in plants was 'The Age of Primitive Vascular Plants. This new period (the second stage) in plant history occurred within the next 50 million years (400-500 million years ago). Some of these developed root systems stems and leaves. They also formed woody tissue, which created stiffer stems, which eventually developed into tree trunks. They became tree-like and up to 40 meters tall, forming the world's first forest. 'The Age of Seed Bearing Plants' was the next stage of plant history where plants were taken to their next step up in the evolution. This occurred around 280 million years ago. This was also the d ...

... detrimental to our environment, you have to take into account that it is almost impossible to entirely prevent pollution. This is scientifically impossible and it would have severely negative economic impact on the industries. So the core issue becomes the fact no matter what, there will always be pollution, as long as these industries exist. So we should focus on how we can minimize this and yet at the same time have an efficient market system? Furthermore, we should also focus on how we can accomplish this so that sustainable growth and development can take place. So there is definitely a need for some form of government intervention to enforce and monitor ...
