.... to grow any sort of crops would be futile. On top of this soil is a thin layer of humus, which simply said is the compost made from the millions of dead animals and plants of the forest. When things such as leaves and animals die their remains are quickly broken down by a limitless amount of tiny organisms. Some insects that do just this sort of thing include: beetles, ants, termites and a host of others. With all of this death happening so quickly you would expect a sort of rotten smell to be in the air. This, however, is not the case. This is simply because everything that is dead in t .....

.... acetyl group. The two acetyl groups combine with a molecule of coenzyme A each to form two acetyl coenzyme A molecules. These molecules are processed in a complex pathway called the Krebs cycle. As the Krebs cycle progresses through both pyruvic acid molecules, six molecules of NADH, two molecules of ATP, and additional carbon dioxide are all formed. FAD picks up a hydrogen atom from each pyruvic acid molecule, and a total of 2 FAD2 are formed. NADH and FAD2 transport their hydrogen atoms and electrons to the electron transport chain. The electrons are passed down the chain of attractin .....

.... plates just under the skin, no head, and a water vascular-system with tube feet. Echinoderms are radially symmetrical, lack specialized ecretory organs, and reproduce sexually. Echinoderms have the ability to regenerate lost or injured body parts. Starfish: Starfishes are free-living echinoderms that have a flat, star-shaped or pentagonal body, usually with a continuous disc that has five or more ray-like extensions called arms. Tube feet are located in an open furrow along the underside of the arms. These arms contain the digestive glands and genital organs. Located on the upper s .....

.... the induced current must point downward. Thus Lenz's law tells us that the current must move by the use of the use of the right hand rule. If the flux decreases, so the induced current produces an upward magnetic field that is "trying" to maintain the status quo. Let us consider what would happen if Lenz's law were just the reverse. The induced current would produce a flux in the same direction as the original change; this greater change in flux would produce an even larger current, followed by a still larger change in flux, and so on. The current would continue to grow indefinitely .....

.... to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of . Finally, the threat of causes many work stoppages and lost production increasing the time and cost required to prepare NASA spacecraft for flight. Benjamin Franklin performed the first systematic, scientific study of during the second half of the 18th century. Prior to that time, electrical science had developed to the point where positive and negative charges could be separated. .....

.... year it is estimated that ten percent of all deaths are related to alcohol abuse. Am astonishing fifty percent of all major automobile accidents, and murders are associated with alcohol. On and on the statistics point to the enormous dangers of alcohol, yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is alcohol dependent. The life span of the alcoholic is about ten years shorter than the non-drinker. The lifetime prevalence for in the United States is as high as fourteen percent. Taking these statements int .....

.... factors that affect brain development. (3,4,5) Our current model of the causation of schizophrenia is very similar to that used to understand cancer. That is, schizophrenia probably occurs as a consequence of multiple "hits," which include some combination of inherited genetic factors and external, nongenetic factors that affect the regulation and expression of genes governing brain function or that injure the brain directly. Some people may have a genetic predisposition that requires a convergence of additional factors to produce the expression of the disorder. This convergence result .....

.... disorder with a DSM-IV diagnosis. The diagnostic criteria for GAD are: A. Unrealistic or excessive anxiety and worry about life circumstances for a period greater than 6 months, during which this person has been bothered by these concerns for more days than not. B. The person has difficulty controlling the anxiety and worrying. C. The anxiety and worry are associated with at least 3 of the following symptoms: 1) Restlessness or feeling keyed up or on edge 2) Being easily fatigued 3) Difficulty in concentrating or mind going blank 4) Irritability .....

.... negative two hundred thirty three degrees Celsius which converts to negative three hundred sixty nine and negative three hundred eighty nine degrees farenhiet.Its extremely frigid tempetures are due to its obvious distance from the sun.Its atmosphere consists of nothing more than methane.Plutos thin atmosphere also contributes greatly to its extremely low atmospheric pressure only one hundred times weaker than that of Earth's. Its surface is made of very rocky material which is believed to be caused by the low tempeture, and atmospheric pressure. Pluto has only one natural satellite named .....

.... damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of man .....
