.... legs of a person with almost always become bowed and the elbows often cannot be straightened completely. Sometimes the person has limited twisting ability at the elbows. The hands are short, and the feet are short and flat. Another sign is double jointedness, caused by loose ligaments in some joints. Achondroplastic children can flex their finger, wrist, hip, and knee joints to an extreme degree because of this. These signs are usually apparent at birth, and can be diagnosed at that time. Affected men average 51.8 inches in height, while women average 48.6 inches. Ther .....

.... Therefore, air resistance doesn't exist on the moon. Also, the amount of air resistance on an object depends on the speed, size, shape, and density of the object. The larger the surface area of the object, the greater the amount of air resistance on it. This is why feathers, leaves, and sheets of paper fall more slowly than pennies, acorns, and crumpled balls of paper. There is another legend that states that when Newton was lying against a tree in an orchard, he was struck on the head by an apple. He wondered what provided the acceleration for the apple to fall to the .....

.... are not produced in sufficient quantities in a depressed person’s brain. Because of this lack, too few messages get transmitted between neurons and the symptoms of depression occur. In Clinical depression the chemicals in the brain are out-of-balance. New technology allows researchers to take pictures of the brain that show activity levels in the brain. These imaging techniques such as f-MRI and PET scan actually create images of how active different parts of the brain are. Some studies with these kinds of techniques have suggested that the patterns of activation in the .....

.... that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to .....

.... John Abernathy, President of the Royal College of Surgeons, Owen was granted membership to the Royal College in 1826. Owen was later appointed assistant in the cataloging of a collection containing thirteen thousand specimens (known as the Hunterian Collection (Rupke 17)). It was probably this that lead Owen interest in the field of anatomy, which eventually lead him into becoming a naturalist. By 1836, he published anatomical work on the Memoir on the Pearly Nautilus (Rupke 119). Within a year, he was giving lectures to the public on the the Hunterian Collection. T .....

.... for their livelihood. (Satchell 30) Over the years, hunting has reduced the animal population drastically. In the 1970's, the number of ducks making annual flights was approximately 91.5 million. In 1995, the number had been reduced to around 64 million. Within 20 years, in short, the duck population was reduced by almost one third, showing the drastic toll hunting is taking on our wildlife. If we assume that other species have been reduced in number at approximately the same rate in recent years, then what are the larger implications for our ecological balance? If this t .....

.... have something to do with this vast new form of medicine. continues to grow every year, which makes it a very important issue in our society, in fact 40% of American use some form of herbal or other in the world today (Jonas). This fact just shows how widely used this method is. According to a survey of 1,539 adults in 1990 and 2,055 in 1997, use of at least one type of alternative therapy during the previous year jumped from 33.8 percent in 1990 to 42.1 percent in 1997 (Mann). These facts show just how fast is growing. The option to ignore the use of is gone. For h .....

.... Basking sharks have, at some point in time, also been known as the elephant shark, the Bone shark, sailfish shark, and sunfish. The reason this shark is occasionally referred to as the Bone shark, is because when they die, they sink (their density is greater then the water's density) and are ravaged among the sea floor, by rocks, etc. (Steel, 1985, 132). However, when they do finally wash up on shore they are usually quite mutilated; their skeletons are all that remain. Hence the name, Bone shark. Although the Basking shark most appropriatel .....
