The Acid Rain Effects On Living Things
.... a mild solution of sulfuric acid and nitric acid. These chemical reactions that change air pollution into acid rain can take from several hours to several days. Sunlight increases the rate of these reactions. Rainwater, snow, fog, and other forms of precipitation containing these mild solutions of sulfuric and nitric acids fall to the ground as acid rain. Years ago, when smokestacks were only a few stories tall, pollution from the smokestacks usually stayed near the ground and settled on the land n .....

Drumlin Formation By Catastrophic Flooding
.... drumlin origin has been applied to drumlins in New York, southern Ontario, the northeast shore of Georgian Bay in Ontario, and to the interpretation of hummocky terrain in southern Alberta, and other areas, by various workers. Shaw suggested as many as 10 meltwater discharges, similar to those which caused the Livingstone Lake drumlins, would be needed to account for drumlin fields in other areas [Shoemaker, 1995, p. 3].
The subglacial meltwater hypothesis of Shaw et al has several parallels to an int .....

Endangered Species
.... or illegal hunting. “The Black Rhino also has a long gestation period of 15 months with an interbirth interval of a single calf every 2.5 to 4 years, making it a slow process for rhinos to be introduced 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 w .....

Cloning And Its Impact
.... physical and biochemical characteristics of an organism, of livestock is accomplished by bombarding embryos of livestock with genes that produce “super” livestock traits; however, this technique is 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 livestoc .....

Evolution
.... states that the changes that occur in animals through the principle of use and disuse are passed on to the animal's offspring (Strickberger 23). Lamarck's theory on evolution was proven false because 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, .....

Acid Rain And Its Origins
.... see what thing's people can do to help stop its effects. If we cannot stop the effects, I would atleast like to know something’s I can do to lessen the effects on our environment.
What is acid rain? 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 .....

Human Cloning

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 .....

Digestive Systems Of Humans, Earthworms, And Grasshoppers
.... glands secrete gastric juices. Hydrochloric acid is released which deactivates the salivary amylase, in turn stopping the chemical breakdown of starch into maltose. Pepsinogen, which is an inactive 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 .....

Plants In TKM
.... (Garden Geranium 1). Again, the bright colored flowers make any bouquet of flowers complete. It is very hard to get any Geraniums to grow in short and cold growing seasons, like in the Pacific 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 we .....

A Big Problem: Shortage Of Fish
.... these waters will all be for nothing if re-opened because the same problem will happen again. Another concern is that the equipment that is used by the fishermen to catch the scallops not only do 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 water .....

Pollution In Eastern Europe
.... out at this time that the pollution that is discussed here is only related to pollution that directly harms people and the environment they live in, not pollution like carbon dioxide or greenhouse 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 th .....

Grasshopper Dissection
.... very educational experience not just for me but for my whole group, I know this because I could see them concentrate and do everything right instead of just screwing off and not concentrating at all. 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 .....

The Origin Of Life

Let us look at the three theories 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 indi .....

The Threat Of Nuclear Energy

You can hear ripping, rending, wrenching, screeching, scraping, tearing sounds of a vast 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 .....

Killer Bees

However, many of the basic African honeybee traits remain, including rapid population growth, frequent swarming, minimal hoarding of honey, the ability to survive on sparse supplies of pollen and nectar, and a highly defensive nature.
Africanized honeybees are more difficult to manage than European honeybees and produce les .....
