Carnivorous Plants
Number of words: 1430 - Number of pages: 6

.... carnivorous plants contain the organic pigment chlorophyll. This pigment helps to mediate a chemical process called photosynthesis. This converts light energy into the chemical bond energy of carbohydrate which is utilized as cellular energy, plant growth and development. Water, carbon dioxide, nutrients and minerals are also needed for survival. In wetlands, where stagnate water contains acidic compounds and chemicals from decaying organic matter many plants have a difficult time obtaining necessary nutrients. It is in these nutrient poor conditions t .....

Among college students, the rate is several times higher. does not occur in any particular "season," although authorities in colleges and schools, where the disease has been well studied, report that they see most patients in the fall and early spring. Epidemics do not occur, but doctors have reported clustering of cases. Transmission: EBV, the virus that causes most cases of , infects and reproduces in the salivary glands.

On Darwin's Theory Of Natural Selection
Number of words: 655 - Number of pages: 3

.... observations about coral reefs (1842), and volcanic islands (1844), but his greatest biological observations were those pertaining to his theory of evolution. Darwin's findings begin in the Galapagos Islands where he noticed a wide array of finches whose beaks were different sizes. He believed that the physical conditions on the island did not affect the birds' beaks, but it was the birds' feeding habits. For instance, the birds with the large, powerful beaks ate large seeds, while the birds with the small or fine beaks, ate small seeds or insects. He .....


Manatees
Number of words: 1737 - Number of pages: 7

.... internal ears on the sides of their head. Their nostrils are closed by valves, so they can accomplish such feats as flips and quick turns without losing any air. Manatees have no hind legs, but instead one big, flat, spatula-like tail (Sentman 327). This feature made people confuse manatees with mermaids for nearly four centuries (O'Shea 66). Many biologists say that manatees possibly originated or evolved from ungulates such as elephants and cows because of the way that they are built, and certain features that they have in common. Like elephants, manatees have .....


Effects Of Marijuana
Number of words: 1053 - Number of pages: 4

.... The hemp plant has many uses and has been farmed for centuries. Marijuana can be taken in three ways, by eating, made into a tea, or smoking (the most popular). Smoking it can be done three ways, through a pipe, a joint, blunt. A joint is a rolled piece of paper that is twisted at the ends. A blunt is normally an emptied cigar wrapper filled with marijuana. In a blunt you can fit much more marijuana. Though a blunt isn't always purely marijuana, it can be mixed with other drugs such as angel dust. The results are varied when someone smokes .....


New High-speed Connections Will Change How We Work And Play
Number of words: 860 - Number of pages: 4

.... modem, data is translated from its digital form to an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Internet today, at speeds of only 53kbps. Even that connection speed is theoretical. Depending on .....


Chemistry
Number of words: 316 - Number of pages: 2

.... I am the vivid part of life. I shield protection for those below me from the sun's intense heat. I am fed and drunk by those who go through hunger. As acid contained in the human body, I digest food and clean out wastes. I am a desperate hope for a cure, yet poison, slowly spreading in the air and along the land. I am the colorful fireworks "sprocketed" across the dark sky when the touch of two soft lips are gently pressed together. I am the warm tears trickling slowly down a child's face when the thought of going to school all alone crosses his mind. I am te pur .....


Isaac Newton
Number of words: 622 - Number of pages: 3

.... him to some of the greatest discoveries in the history of science. In science his main discovery was that when white light passed through a prism, it was broken up into a broad spectrum of colors. When that spectrum was shone back through another prism that spectrum became a white light again. Next he passed a single color of light through a prism, the color was the same when it came out the other end this led him to believe that white light was composed of all the colors. During this time he also formulated the corpuscular theory of light, which states tha .....
