.... are widely referred to as genetic engineering. Transgenic organisms have proved very useful in analyzing the function of gene products because a specific gene can be expressed in all the cells of a transgenic organism and the effect on the organism's development and function can then be monitored. It is also possible to use transgenic procedures to produce animals in which a specific gene has been deactivated in all its body cells. Certain genetic disorders of humans can be studied with this technique in laboratory animals if the disease-associated gene occurs naturally in .....

.... 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, mal-defo .....

.... to the problems. A psychologist's specialty and place of employment determines their working conditions. Clinical, school, and counseling psychologists in private practice have pleasant, comfortable offices and set their own hours. However, they often must offer evening hours to accommodate their clients. Those employed in hospitals, nursing homes, and other health facilities may work evenings and weekends, while those who work in schools and clinics generally work regular hours. Psychologists employed as faculty by colleges and universities divide their time between te .....

.... decline in health, and, in some cases, death. The virus also infects the nervous system. There, HIV may cause dementia, which is a condition characterized by sensory, thinking, and/or memory disorders. HIV infection of the brain may cause movement or coordination problems. HIV’s disruption of the immune system makes infected people susceptible to illnesses that are not normally serious. These diseases are called opportunistic illnesses because they take advantage of the damaged immune system. With the onset of several of these illnesses, an infected person is consid .....

.... fuels--coal, oil, gasoline, and natural gas. Sugar, starch, and paper are compounds of carbon with hydrogen and oxygen. Proteins such as hair, meat, and silk contain these and other elements such as nitrogen, phosphorus, and sulfur. More than six and a half million compounds of the element carbon, many times more then those of any other element, are known, and more are discovered and synthesized each week. Hundreds of carbon compounds are commercially important but the element itself in the forms of diamond, graphite, charcoal, and carbon black is also used in a variety of .....

.... other areas of the body, not just the surrounding tissues. An analogy that fits very well with the study of the endocrine system is that of a message in a bottle. We can think of the body as a river, and a specific hormone may be a bottle containing a message. The organs or glands mentioned above would manufacture the “bottles” (hormones) that would be released into the river (blood stream). If there were no receptor sites for the hormones in the body, then they would continue to flow along the river and probably not make their destination. However, there .....

.... increased. Charles Darwin was one scientist who helped to increase the evidence supporting evolution. Darwin developed the idea of “natural selection” where living things that reproduced in large numbers and survived became dominant and other living things adapted to survive, or they died. Francis Crick, a scientist, co-discovered DNA which opened new doors to the idea of evolutionism (History). DNA is the pattern by which people are created as individuals. Now Evolutionism is the only origin of life that can be taught in public schools. However, in private sch .....

.... is similar, in that it has laws. However, these laws are mostly restatements of known facts. For example, in astrology, they make claims about what you are like based on what day you were born. The things they say, however, are things that are statistically common for those people. They are also very vague, making the chances of being wrong increasingly low. Also, they can be interpreted in many different ways, allowing for unbelievable flexibility in their predictions. A pseudo-scientific theory can always be proven right, which may sound good. However, in m .....
