... have normal vision. For each son born to a mother who carries the gene, there is one in two chance of having X-linked ocular . The description is a hereditary deficiency pigmentation. This could involve the entire body or part of the body. This is believed to be caused by an enzyme deficiency involving the metabolism of melanin during prenatal development. This can be inherited by an dominant or recessive trait. In complete , there is lack of pigmentation in skin and hair, as well as in retinal and iris tissue; in incomplete , skin and hair may vary from pale to normal; in ocular , function may vary from norma to impaired. Impairments may involve the retina and ...

... with short-fiber additives, mostly fiberglass. This is known as a polymer composite. One particular polymer has three times the strength of tempered steel and is being used in bullet proof vests. Another composite will be used to fasten together the sections proposed space stations. have also been used in cars, including the Chevrolet Camaro and the Pontiac Fiero. 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 ...

... fungi is not very clear because scientists have never realy wnt in great deepth , because fungi are not needed commericaly. the ancestors of fungi lived in shallow bodies of water about 600-800 million years ago. Some of the things the fungi had to encounter from living out of water was, there was more sunlight that was normally blocked be the water, and the had to do something about the rapid shifts in tempature and seasonal shifts. Fungi are different from other plants in many ways. The general characteristics of fungi are extracellalar digestion, peculiar structures, growth patterns, their use of spores for reproduction, and their life cycles. Characterist ...

... of and how this affects the physical and chemical properties of each type resulting in different advantages and disadvantages to human health. The way in which fibre helps prevent disease is also discussed extensively in order to prove that clinical nutritionists are right to encourage intake of in increased amounts with caution to the fact that overindulgence may cause adverse effects. Lastly the importance of high fibre foods in conjunction with a healthy lifestyle is presented as the 'formula' for a healthy body and avoidance of fibre depleted foods, a fact which is sadly abundant nowadays, is also mentioned. Since ancient times, foods containing complex carboh ...

... for historical truth. Part of growing up involves the of self. This normally means finding out your family’s history. In “My Place”, Sally grows up feeling that there is a lot about her past that she doesn’t know. “the feeling that a very vital part of me was missing and that I’d never belong anywhere.” When she was a child, her best friend was Winnie the Pooh. She felt that she had a lot in common because they both felt like misfits. Both her mother and grandmother know that Sally doesn’t know much about their Aboriginal heritage, and so therefore tell her that she is Indian. “Come on, Mum, what are we? What do the kids at school say? Anything. Italian, Greek, ...

... the evolution of relevant behaviourist and neurophysiological theories, the most important being O'Keefe (1991); Muller, Kubie, Bostock, Taube and Quirk (1991); and Rolls (1991). The behaviourist theories proposed that a reward or aversive object/event 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 beh ...

... developed possibilities of how it occurred. Many theories were developed, but someone always disproved them. Recently with the discovery of genetic mutation and a new understanding of genes and DNA, the evidence supporting evolution has greatly 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 p ...

... The nucleus breaks into two pieces, releasing energy and two or more neutrons. Each of these neutrons has enough energy to split another heavy nucleus, allowing the process to repeat itself. This is the chain reaction that makes nuclear weapons possible. In a fusion nuclear device such as a hydrogen bomb, lightweight nuclei are forced to fuse at very high temperatures into heavier nuclei, releasing energy and a neutron. In order to squeeze the two nuclei together, an atomic fission bomb is usually used. A fusion reaction releases about four times more energy per unit mass than a fission reaction. The United States supervised the development of the at ...

... to mankind. The possibilities of human cloning are vast indeed, but research in the area has been dramatically restricted in the United States and in some other countries. Pro-life groups that oppose free access to abortion have considerable political power, and were able to have all human embryo research banned by the Reagan and Bush administrations in most of the 1980’s and the 1990’s (religoustolerance). Although the ban was lifted during the first days of Bill Clinton’s presidency, in 1997 he sent a bill to congress marked “immediate consideration and prompt enactment” stating that it would be illegal to create a human clon ...

... bandwidth is faster internet connections. On a normal analog phone line, the fastest internet connection available is 56 kb/s (kilobits per second). With DSL, the normal speed is 384 kb/s with the max at 1.1 Mb/s (megabits per second). With DSL, one's computer could be online at all times. There would be no busy signals or dial-in hassles. If someone wanted to look something up on the internet real quick or check their mail, all they would have to do is start their internet browser or email client and they would be set. DSL wouldn't only make our internet experience more enjoyable, but it would also improve the quality and reliability of normal phones. The ...
