.... the worlds major insect problems. Cockroaches are in this group too. Their are an estimated 3,000 cockroach species in the world. About 55 live in the U.S., and only 4 species ar common household pets. German cockroaches or Croton bugs, are common in the U.S. especially in the northern states. They commonly enter the house in bags or boxes from grocery stores. They tend to cluster in warm moist places around hot water pipes. They stay hidden when they are not eating. Eat Crickets will eat holes in paper or in garments especially those soiled with persperation. They also eat young roots and seedlings, peanuts, garden crops, grain, clothing, and sometimes other inse ....

.... around midnight in the winter. It is named according to its location, Aurora Borealis meaning the northern lights, and Aurora Australis meaning the southern lights. The general name for both is Aurora PolarisC since both displays occur at the earth=s poles. WHAT CAUSES AN AURORA? For many years, the ideas about what causes an aurora were left to old legends and unsubstantiated theories. The inuit believed that the northern lights were the spirits of dead relatives, dancing around in the sky, while the Vikings believed that they were caused by a fire on the edge of the world. In the fourteenth century, Aristotle described the auroras as jumping goats caused by the earth=s v ....

.... of the flukes). These markings are unique to each individual whale, like a fingerprint. The humpback's skin is freqently scarred and may have patches covered with diatoms. Humpback whales have 14-35 throat grooves that run from the chin to the navel. These grooves allow their throat to expand during the huge intake of water during filter feeding. They have small, round bumps on the front of the head edging the jaws. Humpbacks have huge, mottled white flippers with rough edges that are up to one-third of its body length; these are the largest flippers of any whale. The humpback's genus, Megaptera, means "huge-wings," referring to its flippers. The flippers may have ....

.... To this name the Arabs affixed the article ‘al’, thus giving al-khemeia, or . HISTORY OF ALCHEMY: From an early period the Egyptians possessed the reputation of being skillful workers in metals and, according to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were incorporated. This black powder was mystically identified with the underworld form of the god Osiris, and consequ ....

.... of young skin. Consequently, when these proteins breakdown, the skin will sag, and the muscle will lose its firmness. Another sign of passive aging is the breakdown of lipids at the biochemical level. As aging membranes leak during this lipid degeneration, a fatty, brown pigment known as lipofuscin accumulates. As this happens, the mitochondria, or the “powerhouse of the cell” begins to break down, thereby decreasing the amount of energy that is being supplied to the cell. This cellular degeneration may be set into action by highly reactive chemicals known as free radicals. These molecules have an unpaired electron in the outermost valence shell. This cause ....

.... taken and who produced it. Equally important, in the seventh paragraph Viscusi states that "cancer researchers" generally note. Again he fails to let the reader know the credentials of the cancer researchers. Another example of poor credentials is when Viscusi states some percentages in "a 1991 survey of company smoking policies". He again fails to let the reader know the credentials of the survey. Another explanation as to why Viscusi's article is not successful is because the organization is confusing. The thesis Viscusi is trying to prove is that the are exaggerated. He fails to support his thesis because his main points in his story are all scattered and have no organiza ....

.... amounts but are never-the-less effective in producing instinctive behavior when detected by the nose. In insects and animals, most sexual and social behavior is controlled by pheromones. Humans have used perfumes for thousands of years, but there is a basic difference between perfume and pheromones. Pheromones are produced by the body and usually do not smell at all pleasant, whereas perfumes are either synthesized or extracted from natural products and are employed because of their pleasant smell. Scientific research suggests that there are human pheromones for both the male and the female. Females have a better developed sense of smell and testing indicates that the ....

.... to be in orbit by the mid 1990’s. The idea of having an operable, livable, space station seemed to be inconceivable to everyone who heard that speech. As the ideas for this project began to take off, the main concern was money. How much funding would be necessary to construct a space station? At first, NASA could only work within the agency’s estimated $8.5 billion dollar budget. It was in 1984 when the first construction plan was unveiled, called “Freedom.” A “power tower” concept was designed, which is a long slender unit that would be the center of the entire structure. This tower would be a long, narrow piece of latticework ....
