.... trachea. The air then passes down the trachea which is a long “windpipe” that is lined with constantly moving cilia. These cilia whip back and forth and trap foregin objects and keep them from entering the lungs. The air completes its path down the trachea when it reaches the bronchus which is a speration of the trachea into the two different lungs it is used to carry oxygen to different parts of the body. These bronchus break into many bronchioles which then branch into many many microscopic tubs that cary the oxygen to every part of the lung till they meet the thin sacs called aveoli. Aveoli are thin sacs in the lungs that carry oxygen in and carbon dioxide out of the b ....

.... the egg cell of another which creates a genetically matched life form. The actual merging process between the cells is called Nuclear Transfer. In this process the nucleus of one donor cell is removed and placed into a lab dish and starved of nutrients; it is then placed into a lab dish with a fertilized egg cell. Naturally, the cell that was starved will try to fuse with the healthy cell but it will need a little help. These two cells are then electrified thereby causing the two cells to fuse together combining their genetic structures. Cloning / 3 Now that we have established the scientific basis of cloning, let me tell you how cloning can ....

.... medicines, foods, building materials, and other products made from plants. If one were to try and pin-point the most important thing a botanist does, it would be impossible. They do so much for us, yet get little recognition for it. Whenever you take an aspirin, eat some vegetables, or even sleep in the house that was once built, you can thank a botanist for it all. Many people, such as myself, would wonder why someone would want to be a botanist. The main reason anyone can name is that plants have intrigued people for thousands of years. Plants are used for decoration, as well as our basic needs, such as: food, shelter, and even the air we breathe. Today, our world r ....

.... has been explained as resulting from the deceleration of its angular motion through its magnetic interaction with the outflowing solar wind, so that this feature should not have been considered a constraint on theories of the origin of the solar system. The many theories concerning the origin of the solar system that have been advanced during the last three centuries can be classified as either dualistic or monistic. A common feature of dualistic theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out filaments of gas from which the planets condensed. Theories of this type encounter enormous difficulties in try ....

.... is the Western Canadian Boreal Forest which is a large producer of wood for the United States construction industry. However, climatic changes has had large and impacting effects on the construction industry. Compared to eastern Canada, the southern boreal forest region of western Canada has a relatively dry climate. Thus, drought effects are one of the major concerns being addressed by researchers in this region. climate modellers have predicted a large increase in temperature for this region, which could lead to even drier conditions and enormous stresses on vegetation in the western Canadian boreal forest. This type of impact was observed following the 1988 drought it expe ....

.... Many believe that continuing to provide genetically constructed inventions in this world is ethical, which means that these inventions conform to one’s moral standards (Epstein 5). Others argue that such inventions as human clones, which are genetically constructed humans, and other genetically created figures, are wrong and should be stopped (Epstein 5). Overwhelming textual evidence proves that genetic engineering is not beneficial to society. Accordingly, genetic engineering is unethical and therefore should be stopped. One reason why genetic engineering should cease is because genetic engineering disrupts society’s moral values and causes society to act ....

.... that it seems everyone else has. A. They may develop anorexia because they are dissatisfied with themselves. B. An anorexia will take drastic measures to change her body image in an attempt to fit in. An Conclusion: It has not yet been pin-pointed what the exact cause of anorexia is. Many factors play a role, including self-esteem. Children need to be showed love and caring in order to gain the appropriate levels of self-esteem.  Anorexia is a big issue in society today. Girls and boys are developing anorexic symptoms as young as age five. While anorexia can be detected in boys, girls, men, and/or women of all ages, “the most common age ....

.... of years ozone has been protecting the earth " by absorbing ultraviolet or bad radiation from the sun ( Rowland, 1992, p.66 ). This natural umbrella protecting mankind has recently suffered the effects of industrialized society. This " ozone shield is dissipating " and the cause is laid primarily to man - made chemicals ( Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are released, " the ozone layer would be weakened to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the environment. Ozone depletion has been described as " p ....
