... 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 shouldn't let just anyone be able to modify bacteria, or the human genome, but we shouldn't let our fears blind us to the possible benefits of wide-scale genetic engineering. Medical uses for this technology are virtually endless. With genetics we can filter out any genetic defect, no more down-syndrome ...
... The British government has recognized that sulfur emissions from power plants in the United Kingdom are contributing to acid deposition in Scandinavia. Canadian emissions contribute substantially to in the northeastern United States, for example, and much of the sulfur falling in eastern Canada is believed to originate in the United States. In 1986 the U.S. National Academy of Sciences acknowledged that from U.S. sources had become a serious problem in the eastern United States and Canada. Although the Canadian government has agreed to reduce sulfur dioxide emissions, the United States has not placed limitations on its sulfur emissions that may drift into Ca ...
... lower than the 21% oxygen concentration available in the atmosphere (Barstow et al. 1999), hence special problems pertaining to the acquisition of sufficient amounts of oxygen arise for aquatic organisms---namely fish. Fishes have had to develop adaptations that enabled them to adapt to this problem. Since water contains an insufficient concentration of oxygen, fishes use gills to obtain the required amount of oxygen---via the counter-current exchange process. As water enters the mouth of a fish, it passes through slits in the pharynx, flows over the gills, and exits at the back of the operculum (gill cover) (Campbell 1997). This ventilation process serves to bri ...
... in treating diseases of the thyroid. Nuclear power is changing the face of medicine with new cures and tests that will cure millions.. Nuclear power can be converted into strong and efficient nuclear energy and be used for many purposes. Nuclear power reactors generates heat that is converted into steam. The steam can be used directly for energy. This energy is used in transportation. Most military subs are now ran by nuclear energy. The most used purpose of nuclear energy can also be used to generate electric power for example in a commercial nuclear power plant. Another way to produce nuclear energy is by gas-cooled reactors with either carbon dioxide or helium a ...
... Responsible Party? 1.) Owners and operators of waste sites. i) CERCLA actions against dissolved corporations are permissible ii) If one is the owner or operator, liability may attach even if some other party in the past placed hazardous wastes there. ( The seller of a foundry was found liable under CERCLA when it was sold for $25,000, but was appraised at $200,000, suggesting the decision to sell was for disposal of hazardous materials.) A vendor is not an owner if it did not own the property at the time of toxic discharge from the facility. iii) A parent company may be considered the owner, despite the formation of a subsidiary with day to day control ov ...
... in a hypnotic trans. Under hypnosis, sometimes weeping and shouting with agony and terror, they recover buried memories of alien encounters. There has never been physical proof of any abduction yet to be provided. The Roswell incident is now generally regarded as one of the most important UFO events in history, an extensive review of the UFO literature of the 1950s finds no mention of it beyond the first press accounts in early July 1947. The only know reference to it as a UFO crash was in a 1955 lecture by broadcaster and UFO enthusiast Frank Edward. Even in the 1960s the UFO literature mentioned it only three times, twice in both brief instances, in the la ...
... At this stage it is estimated that 90% of all companies have at least one macro virus resident somewhere in their computer systems. Types of Viruses Under the main heading of viruses are three types of harmful computer programs, not all of which hide and replicate. The first of these is the Trojan Horse programs, the name of which comes from the Greek legend that told how Greek soldiers gained entry to the city of Troy in a giant, hollow wooden horse and thus captured the city, ending the Trojan War. Though not technically a virus it is still dangerous and could cause permanent damage to your operating system. A Trojan Horse program is a program d ...
... they usually only grow to about 10 feet. They weigh an average of 1300 pounds. Manatees live in small family groups sometimes up to herds of 15-20. After a gestation of up to 6 months, usually a single pinkish calf is born. Manatees ferquently communicate by muzzle to muzzle contact and when alarmed they emit chripy squeaks. The number of manatees has been reduced over the past several years due to heavy hunting for their hides, meat, and blubber oil. Some governments, including the United States, have placed the manatees under the endangered species list. One practical reason for this is that they have proved useful in clearin girrigation and transport chann ...
... 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 ...
... Date of Discovery – Circa 3000 BC ? Discover – Unknown ? Name of Origin – From the Old English word geolo (yellow) ? Symbol Origin – From the Latin word aurum (gold) ? Uses – electronics, jewelry, coins ? Obtained From – crust of the earth, copper ores Atomic and Chemical Properties: In it’s usual state – atomic mass number 197 – gold is stable. However, there are radioactive (unstable) isotopes of mass number 186 to 196 and 198 to 203. Gold normally exhibits a chemical valence of one or three. Gold is the “noblest” of the noble metals (gold, platinum, palladium, and rhodium), so termed ...
