.... yield, and our fish population will die. Fishermen also clean there fish and throw the guts overboard into the ocean. Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of those products I just named regularly end up in water. About 65,000 chemicals are used commercially in the U.S. Today, with about 1,000 new ones added each year. Only about 300 have been extensively tested for toxicity. I think that since our oceans are doing so bad the U.S. should put a ban on new, and old, pro .....

.... societal issue addressed is expressed from all point of views, and the following will further strengthen and help you understand their points. “The procedures used in human embryo cloning have been around for many years, and have been used in the cloning of cattle and sheep embryos, for the production of animals with known genetic traits. The news of human embryo cloning did not surprise many people in the scientific community, but it shocked the general public.”(psu.edu) Many biologists believe that they have a personal duty to the improvement of society, perhaps .....

.... your potential. Traits such as what you look like are inherited from your parents. Your potential is also inherited from your parents. Chromosomes contain the information of a person's potential height, potential strength against disease, and other physical characteristics. A human being has 23 pairs of chromosomes in every cell in his or her body (except reproductive cells). If, during a stage of growth, a fetus somehow loses one of these chromosomes, the baby may die, or have a birth defect. Since this error is written on their genes, they may pass it on to their .....

.... exact copies of the same genetic makeup in two to eight separate petri dishes. Even though this process sounds simple enough it has never fully worked because of abnormalities that occur like if the embryo is developed by two sperm cells the chromosome count is wrong. Another is as the cells duplicate they usually do not make it passed the 32-cell stage or 64 because of abnormalities in the environment or just because the process is not natural. The real reason why it does not work yet is not clearly known at the moment. Since became such a distinct possibility with Dolly b .....

.... and studies, there is now physical proof that human beings may have evolved from ape-like creatures. Even with this, there are still disputes in the paleoanthropological field of whether or not this is true. Still, many choose to believe their religious creation stories where a God created humans. Whether it is Johanson's idea on human evolution or Leakey's or even the Roman Catholic's creation story, all are an individual own interpretation and neither wrong nor right. A paleanthropologist by the name of Donald Johanson is one of the many who have a very different view .....

.... 38„aC, despite living in very different habitats. However if body temperature rises above its optimum level (usually around 40„aC in mammals) then the enzyme rate inside the body will go into sharp decline. This is because enzymes are proteins, and become denatured. One of the first organs to be affected is the brain. Since the brain controls breathing and the circulation, the rise in body temperature disrupts the normal functioning of these important systems. If the body temperature decreases dramatically (hypothermia) then this will slow metabolic activity and impairs brai .....

.... is an endangered species that inhabits pine forests in an historical range from Texas to the Atlantic coast (Jackson, 1986; Reed et al., 1988). Picoides borealis nest in clans or family groups that usually consist of one breeding pair and 2 non-breeding male helpers (Jackson, 1986 ). This group establishes and defends a territory that includes foraging habitat and nesting "cavity trees" (Copeyon et al., 1991; Jackson et al., 1986; Rossell and Gorsira, 1996). Red-cockaded woodpecker clans excavate cavities in living pines, and have established a living and fora .....

.... spy plane (Misage 15). According to many Americans, these are not the only flying machinery which exists in Area 51. On July 7, 1947, two ranchers in Roswell, New Mexico, observed something that would be the beginning of what might be one of mankind's most unexplained phenomenons in history. According to these ranchers, (who asked to be anonymous) a flying object came out of the South East and went flying into the Northwesterly direction. These ranchers observed it for 40 or 50 seconds before it disappeared behind the hills. They did not recall it making any sounds (Roswel .....
