.... banana leaves (or even walk up a window pane). 6. Nearly 1,000 kinds of bats account for almost a quarter of all mammal species, and most are highly beneficial. 7. Worldwide, bats are the most important natural enemies of night- flying insects! 8. A single brown bat can catch over 600 mosquitoes in just one hour! 9. Tropical bats are key elements in rain forest ecosystems which rely on them to pollinate flowers and disperse seeds for countless trees and shrubs. 10. Bat droppings in caves support whole ecosystems of unique organisms, including bacte .....

.... in the Lymph glands and bone marrow are abnormal or immature. In Granulocytic Leukemia this causes an increase in white blood cells known as granulocytes. Granulocytes are made in the bone marrow, and other tissue. Granulocytes that are affected by leukemia cannot fight of infections. There are two ways in which leukemia can occur. One is acute, and the other is chronic. Acute leukemia is found most in children. It progresses rapidly. Acute leukemia causes red blood cells to decrease, the cells are then replaced by abnormal ones. This cause .....

.... ethical, and legal implications. The first step to understanding genetic engineering is to know the start of its creation. Genetics achieved its first foothold on the secrets of nature's evolutionary process, when an Austrian Monk named Gregor Mendel developed the basics of how genetics work. Using this, scientist studied the characteristics of organisms for the next one hundred years following Mendel's discoveries. These early studies concluded that each organism has two sets of character determinants, genes (Stableford 16). For instance, in regards .....

.... Why does deforestation occur? There are a many answers to that question but the main ones are: Ø For agricultural purposes eg space for building. (overpopulation) Trees are logged for the purpose of space. In this day and age the human race is multiplying and therefore we require more space to expand cites and build more houses. To do this world government cut down any forests in their way. Ø Industrial commercial purposes Big industries also contribute to deforestation. EG "Macdonald's uses 800 square miles of trees just for the paper packaging of .....

.... the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed up, .....

.... development of larger and more cost-efficient steam-power plants made it obvious that only very large and costly hydroelectric installations could compete effectively, and that the federal government would have to assume a major share in their construction. Motivated by the search for the multiple use of water resources, including navigation, flood control, and irrigation, in addition to power production, the Tennessee Valley Authority, or TVA, started government participation in large-scale waterpower development in 1933. Most major installations dep .....

.... older sister, Bronya, had already left Poland to study medicine at a university in Paris. Marie sent a portion of her earnings as tutor and governess to Paris to help pay for her older sister’s medical studies. In 1891, when Marie was twenty- four years old, she was invited to live with Bronya upon her completion of medical school. This enabled Marie to enroll at the University of Paris and begin her own dream of becoming a university student. Marie studied mathematics, physics, and chemistry. It was upon enrollment in college when she changed her firs .....

.... edge are usually different from those found on the surroundings higher ground. Especially reminiscent of natural ponds are large plant's that leaves overhanging the water's edge, and plants with long thin, grassy foliage that grows in the shallows. These will all help to cover the water edge, which is almost never seen in a natural pond. Most nurseries sell aquatic plants. A pond that is meant to look natural requires much less maintenance than a formal pool, were clean, clear water is generally preferred. If the site has a low area, a pond is a good choice i .....
