... it will spread. Cancerous cells lack the sticky coating that causes normal healthy cells to stay together because cancerous cells lack it they can break off and implant somewhere else in the body. The cancerous cells that break off from the primary tumour are usually carried through the blood. What causes cancer cells to be abnormal? They create extra chromosomes and more DNA then normal cells do. Lung Cancer What usually happens with lung cancer is that the cilia in your throat that usually help keep chemicals and other harmful particles out are destroyed sometimes by smoking or if you work around certain chemicals. What happens is that harmful chemicals get into your lungs and ...

... kinds of causes that drastically cut Down the number of these endangered species: Direct Causes Direct Causes is when the animals are purposely hunted, trapped, fished, whaled, or seled to extinction. Hunting for sport has been responsible for endangering such animals as the Polar Bear and the Siberian Tiger. But the endangerment of most species that are hunted or trapped today results mainly of commercial activities. Among the animals that have become endangered for commercial reasons are several species of whales, including the enormous Blue Whale; many of the spotted cats, such as the Cheetah; and some kinds of Alligators, Crocodiles, lizards, and snakes. the Whales have been kiled ...

... insulin, and human growth hormone in commercial quantities; - existing antibiotics by more economical methods; - new kinds of antibiotics not otherwise available; - plants with resistance to some pesticides, insects and diseases; - plants with improved nutritional qualities to enhance livestock productivity. Methods: - Manipulation of the Gene pool, which is related to Hybridization which is the breeding of species but the species are not the same but they are related. - Chain reaction is the production of many identical copies of a particular DNA fragment. - The utility of cloning is important, it provides the ability to determine the genetic organization of particular regions or whol ...

... for an ideal metabolic rate (aquacult.htp). In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm. The procedures for this experiment are those that are referred to in Duncan and Townsend, 1996 p9-7. In our experiment howe ...

... that died on the Challenger? Sharon Christa Corrigan McAuliffe, born in 1948, was the famous winner of the teacher-in-space program, was a high school teacher at Concord, N. H., a wife, and a mother of two children. She touched the lives of all those she knew and taught. As a school official in Concord said after her death, "To us, she seemed average. But she turned out to be remarkable. She handled success so beautifully." She also wanted everyone to learn more, including herself. Demonstrating her aspirations after entering the space program, she is quoted saying, "What are we doing here? We're reaching for the stars." Also, after reflecting on her position, she said in A ...

... a comet, since I had been looking at M70 last month, and *knew* there wasn't any other objects there." Thomas Bopp explains his story like this, "On the night of July 22, 1995 some friends and I headed out into the desert for a dark of the moon observing session. The site, which is west of Stanfield, AZ and a few mile south of Interstate 8 is about 90 miles southwest from my home. My friend Jim Stevens had brought his 17-1/2" Dobsonian. We started the evening observing some of the Messier objects such as the Veil and North American Nebulae in Cygnus, when Jim said " Let's look at some of the globulars in Sagittarius." We started our tour with M22 and M28, observing at 50X and then ...

... plants and cars, the cumulative effect of air pollution poses a grave threat to humans and the environment. In many places smoke from factories and cars combines with naturally occurring fog to form smog. Smog has been long recognized as a potential cause of death, especially for elderly persons and those with severe respiratory ailments (like asthma). Air pollution originally resulted from large-scale use of heating fuels (like coal and wood). Water Pollution Since the beginning of civilization, water has been used to carry away waste. Rivers, streams, canals, lakes, and oceans are currently used as wastebaskets for every kind of pollution man could create. Water has the capacity to ...

... pit of despair, where it may seem as if the only way out is suicide. There are two types of bipolar, bipolar 1 and bipolar 2. Bipolar 1 is diagnosed differently than bipolar 2. Bipolar I is diagnosed when person has a manic episode and has had no depressive episodes in the past. However, after the first manic episode occurs, depressive episodes often follow. Most people (over 90%) with Bipolar I experience two or more manic episodes in their lifetimes. (site.health-center.com/brain/bipolar/basics.htm). People with Bipolar II have depressed mood followed or preceded by a hypomanic episode. People with this type bipolar disorder never have a full-blown manic episode. Because of this, Bipol ...

... occurs do to the will of God, others, like Charles Darwin believe that it happens based on chance or natural selection. Whatever you believe or disbelieve, life cannot be planned. No matter how hard a person attempts to "plan" their path in life, it is by chance and luck where that path takes us. Darwin's career was also based on chance, not planning. Darwin never planned to become a scientist or the father of natural selection. It was by pure chance that he obtained the job on the voyage of the Beagle, which started his career. Darwin stated about this voyage that, "The voyage of the Beagle has been the by far the most important event in my life and has determined my whole career. . ...
