Endangered Species
.... back into the world by birth” (International Rhino Foundation 3). “The Black Rhino is illegally hunted for its ivory horn that ranges between one foot to one foot eight inches long” (Speart 26). The animal is slaughtered for its horn while its carcass is left for the vultures.
Since the Black Rhino was put on the endangered species list in the 1980s, conservation agencies have aided to help the Black Rhino to rebound. “Now under strict control, the population of Black Rhinos has risen to at least 2,500 in and around parks and on private land in eastern and southern Africa, an increase of 100 from three years ago” (Davies .....

Cloning And Its Impact
.... not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult cells; therefore, cloning from an adult cell would make it easier to alter the genetic material. The goal of transgenic livestock1 is to produce livestock with ideal characteristics for the agricultural industry and to be able to manufacture biological products such as proteins for humans.
Farmers are attempting to produce transgenic livestock already, but not efficiently, due to the minimal ability to alter embryos genetically. Researchers can har .....

Evolution
.... it incorrectly asserts that organisms can change their inheritable traits. This assertion was shown to be untrue when the theory of natural selection was conceived.
The idea of natural selection was formed by both Charles Darwin and Alfred Russel Wallace in the mid-1800s. Unaware of each other's work, they developed the same theory independently. Originally the theory was scoffed at by the scientific community, but now it is widely accepted. The theory of natural selection states that individuals with the most favorable traits will be more likely to survive and pass these favorable traits on to future generations (Volpe .....

Acid Rain And Its Origins
.... Acid rain is the name commonly given to the deposition of a cocktail of acidifying compounds to soils, surface waters and buildings. These compounds arise mainly from the combustion of fossil fuels. In some parts of the United Kingdom, natural ecosystems have a significant acid-neutralizing capacity and acid rain has little impact on them. In other parts, the neutralizing capacity is limited, and terrestrial and aquatic ecosystems are sensitive to acid deposition. In acid-sensitive areas, acid rain degrades the terrestrial environment and causes damage to plants and the soils in which they grow. Substances are released wh .....

Human Cloning
.... over the genetic profile of our children (Hopkins, 8).
Eugenics
Human cloning is accomplished through a field of science known as eugenics, which basically is an attempt to improve the human race. Advances in eugenics have only helped mankind in pushing forward to a greater civilization, a more perfect evolution (Silberner, 5). When new innovations in science are not encouraged but prohibited, they inevitably change into an undercover procedure. Human cloning is already prohibited in Britain and likely soon here in Canada as a result of new legislation held before the commons. If this happens, then it will develop into a s .....

Digestive Systems Of Humans, Earthworms, And Grasshoppers
.... enzyme, will change to pepsin, an active enzyme, when mixed with hydrochloric acid. Pepsin breaks down proteins, forming chains of amino acids called polypeptides. Chyme, a mixture of churned food, mucus, and digestive enzymes, is formed and will pass through the pyloric sphincter into the small intestine.
The small intestine is made up of three parts called the duodenum, jejunum, and ileum. All three parts aid in peristalsis. They also help with the chemical breakdown of simple sugars, amino acids, vitamins, minerals, and fats. The villi, which is a finger like protrusion, contains veins, capillaries, and arteries. This .....

Plants In TKM
.... Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just as good. Most people use them for crawling things to go over doorways and porches. Porches in the south were a very important place of the house. To have really colorful plants meant that it was a very happy place to be on warm summer night looking at all the different flowers. The really cool thing is the vibrant hanging masses of pea-like blue or violet flowers. One downfall of Wisteria is that if you happen to eat it, you get .....

A Big Problem: Shortage Of Fish
.... just that, but they also pick up everything else in their path. This has an impact on all marine life, particularly species such as sponges and barndoor skate which were almost forced to extinction because fishermen can't control what is being caught in the nets. The final concern is that reopening the waters that have been closed would set a bad example, by showing those involved that political pressure will prevail.
On the other end of the spectrum, are those fishermen who rely on the profit made from their job. And since there are already about 200 more boats than experts estimate are really needed, this loss of water .....

Pollution In Eastern Europe
.... gases or other factors concerned with the global warming issue.
The causes of environmental problems and the actual problems that were caused are the first subject that must be explored. Air pollution is by far the most serious pollution problem is eastern Europe. In general, the problem was caused by the burning of coal in industry and lead-based diesel non-desulferized petrol in cars. This resulted in very high amounts of sulfur oxides (particularly sulfur dioxide which is the number one pollutant), nitrous oxides, ozone, suspended particulates, carbon disulfide, and chlorine . The serious sulfur dioxide problem was exacerb .....

Grasshopper Dissection
.... I never knew that a grasshopper had so many complex parts to it. The jaw alone amazed me. I must say that the temperature in the room made those little things stink like a son of a gun. But all in all it was fun and I can honestly say that I actually learned something this year.
In conclusion I would just like to state that this project has been a blast, I don’t even mind writing these little papers because it is fun. I'm not just saying this to suck up but I do enjoy Biology not just because I love nature but because you made it fun Mr. Thompson. Thanks for a great year I signed up for Anatomy and Chemistry .....

The Origin Of Life
.... in depth. The evolutionist theory made known by Charles Darwin, states that humans came from his theory “survival of the fittest.” Charles Darwin based his theory on individual chances that determined the fate of the species. “Charles Darwin as we recall based his explanation of natural selection among individuals with equal chances of survival upon the following principles. The phenomenon of species change results from the fact that in each generation those individuals are chosen or selected out whose physical equipment and behavioral potential best correspond both to the risks and possibilities of their environment.”(1) Darwin .....

The Threat Of Nuclear Energy
.... machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature’s arsenal, hydrogen. Near-molten fuel fragments shatter nearly incandescent graphite, torching chunks of it, exploding the hydrogen. The explosion breaks every pipe in the building rocking it with such power that the building is split into sections (11-13). You look down at your body and notice that it feels hot and your hands look different. Unknown to you a tremendous amount of neutrons are hitting your cells and taking chucks out of your s .....
