... and 8 molars- begin to develop pior to birth. They are eventually replaced- beginning around the age of 6 -by 32 permanent teeth.: 4 central incisors, 4 lateral incisors, 4 cuspids, 8 bicuspids (premolars), and 12 molars. The 4 wisdom teeth develop after the other 8 molars, as the jaws increase in size. If this increase is insufficient, the wisdom teeth may become impacted, that is wedged between the jawbone and other teeth, sometimes resulting in pain and inflammation. The upper teeth, called maxillary, and the lower teeth, called mandibular, are shaped in such a manner that they interdigitate (fit together) when the jaws are closed. This fit is essential for th ...

... energy. Children who do not meet their needs for energy may stop growing and gaining weight. To try to reduce the effects of a diet low in energy people usually become less active. In severe cases, a low energy intake results in starvation. Children, especially those under 5 years of age, suffer from the effects of starvation more quickly than adults. In severe situations, they can develop a condition which is life threatening called protein energy malnutrition. This means that their diet provides too little energy and protein. Kwashiorkor and marasmus are the two most common diseases caused by lack of protein and energy. In developed countries, diets very low in ...

... Vegas has the highest per-capita suicide rate in the country. This coincides with its enormous expansion, yet the most talked-about suicides -- those of tourists leaping from hotel balconies after losing everything they had -- are dangerous myths for a city poised to become America's newest economic icon. In fact, tourists taking their own lives surrounded by the glamour of the Strip comprise only a small percentage of the fatalities. The bulk are those who moved here for jobs, who live just beyond the lights. Eight times as many residents kill themselves here as do visitors. Second, I am told that in Las Vegas I will feel more alive. Anything can be had here; this ...

... idea is that alternative versions of genes account for variations in inherited characters. Different alleles will create different variations in inherited characters. The sescond idea is that for each character, an organism inherits two genes, one form each parent. So this means that a homolohous loci may have matching alleles, as in the true-breeding plants of Mendel's P generation(parental). If the alleles differ, then there will be F hybrids. The third idea states that if the two alleles differ, the receessive allele will have no affect on the organism's appearance. So a F hybrid plant that has purple flowers, the dominant allele will be the purple-colo ...

... been accused of having a 19th Century approach to life in the last third of the 20th Century. But who in reality is using arguments of a bygone Century? It is an incontrovertible fact of biological science - Make no Mistake - that from the moment of conception, a new human life has been created. Only those who allow their emotional passion to overide their knowledge, can deny it: only those who are irrational or ignorant of science, doubt that when a human sperm fertilizes a human ovum a new human being is created. A new human being who carries genes in its cells that make that human being uniquely different from any and other human being and yet, undeniably ...

... found in the glossary. The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2.75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like telephone poles carrying wires across the city. This is called the nervous system. The nerves in the body don't just send messages from the brain t ...

... once, why can't they happen again? Let us take a look at the most horrible, so far, of the plagues: The Black Death. It took Europe by storm from approximately 1345 to 1361. It would also make small comebacks throughout the next 400 years, but never like it did the first time. It also reached into Africa, China, Russia, and the Scandinavian countries. It was truly a worldwide pandemic. But, it has a secondary effect that not many people are aware of. The colonies of Greenland, settled by the Vikings, were stricken by the plague and they soon disappeared. It is known that these colonies kept in contact with "Vinland", which was near New Foundland, in Canada. ...

"The ingenuity and determination of PWS children in surreptitiously obtaining edibles is almost legendary and belies their cognitive defects. Serial weighing may be the only way to discover whether such a child is, in fact, stealing food"(Finey,1983). PWS occurs in about l in 10,000 births. It occurs in both males and females equally and is found in people of all races and all nations.It is one of the ten most common conditions seen in genetics clin ...

... would be done to him?' The answer was obvious: the pound, and the chloroform. No human being with a spark of pity could let a living thing suffer so, to no good end." (James Rachel's The Morality of Euthanasia) The experience of Stewart Alsop, a respected journalist, who died in 1975 of a rare form of cancer gave an example on the morality of euthanasia. Before he died, he wrote movingly of his experiences with another terminal patient. Although he had not thought much about euthanasia before, he came to approve of it after sharing a room with Jack. While growing up, each of us learns a large number of rules of conduct. Which rules we learn will de ...

... dignity is misconstrued. Pro-euthanasia groups advocate self-dignity, personal choice, economic well-being, happiness, family support, and individual rights. The word euthanasia simply means good death, but has come to mean causing death with intent, whether by doing something (commission), or by omitting something(omission). Euphemisms of the pro-euthanasia movement, include "right to die", and "death with dignity". The term "passive euthanasia" is often applied to the withdrawal of useless treatment that is onlyprolonging the dying of a person. This needs to be differentiated from withdrawing of something that is actually keeping them alive, the withdrawl o ...
