.... it develops into a vesicle and then a painless ulcer, usually one to three centimeters in diameter with a black necrotic (dying) area in the center of the ulcer. Lymph glands in the adjacent area may swell. About twenty percent of untreated cases of cutaneous anthrax will result in death (www.cdc.gov). Deaths are rare due to antimicrobial therapy. When anthrax is contracted by inhalation the initial symptoms resemble a common cold. After several days, the symptoms may progress to a severe breathing problems and shock. The inhalation of anthrax spores usually results in deat .....

.... humanity in many ways. The origins of cloning lie in the agricultural history of humanity. Therefore the perceived gap between cloning and our nature are not so distant, as cloning has been the means by which humankind has cultivated flora for a millennia. In addition, selective breeding has been the means by which humankind has manipulated fauna for its own ends. In both cases genetic manipulation does serve humanity on many practical levels. Secondly, humankind has genetically engineered many species through selective breeding. The potential of cloning in food production .....

.... assistance from other organizations such as the Senate Agriculture Committee (SAC), National Academy of Science (NAS), National Resources Defense Council (NRDC), and Consumers Union (CU), the EPA has made a notable progress. Throughout the years, consumers have pushed for research of the chemicals and substances that produce agricultural and what these do to our internal system. Congressman, James J. Delaney was also convinced that too many pesticide chemicals were found in foods. So in 1958, the House Select Committee investigated the use of chemicals in food products an .....

.... that can be extracted from their body. This oil is used to lubricate small parts in watches. Cheaper oils have been found, so dolphins are not hunted for this reason anymore. Dolphins can be caught in tuna nets by accident. Since dolphins have to breath at the surface they drown in tuna nets. It is estimated that 4.8 million dolphins were killed in tuna nets from 1959 to 1972. Under pressure from animal rights activists tuna consumers will not accept tuna from canners that do not protect dolphins. Animal rights activists also believe that dolphins shouldn't be in captivity f .....

.... of a depressive episode include anhedonia, disturbances in sleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts of death and suicide (Hollandsworth, Jr. 1990 ). The manic episodes are characterized by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior (Hollandsworth, Jr. 1990 ). Bipolar affective disorder affects approximately one percent of the population (approximately three million peo .....

New are being created with more strength and flexibility by combing two chemically different and producing a block copolymer. Combinations of block co and composites and intended for use in booster rockets and in materials of Earth-orbiting installations. Most common are usually solid, but a new class of is being introduced in a liquid crystal state. Although these still have the physical characteristics of liquid, they are structured more like solids. Many li .....

.... will motivate a rat to move towards or away from the location along a reward gradient, and this has been shown to be the case with rats in a maze situation (O'Keefe, 1983). Indeed, this situation does not require the rat to have a concept of absolute space; it may depend on associations between cues and responses which are provided by the maze structure itself. However, O'Keefe & Nadel (1978) identified spatial behaviours which they argued would require the existence of an allocentric map: detection of changes within the environment; navigation to the goal from a differen .....

.... hormones. The first cloning of animal cells took place in 1964. John B. Gurdon took the nuclei from tadpoles and injected them into unfertilized eggs. The nuclei containing the original parents’ genetic information had been destroyed with ultraviolet light. When the eggs were incubated, Gurdon discovered that only 1% to 2% of the eggs had developed into fertile adult toads. The first successful cloning of mammal was achieved nearly twenty years later. Scientists from Switzerland and the U.S. successfully cloned mice using a method similar to Gurdon’s, but required one extr .....
