.... grazing animals and occasional fires. Producer: An autotroph organism (grass). Consumer: Organism that eats producers (caterpillars, bison). Primary consumer: Organisms that eat consumers (chicken, meadowlark). Secondary consumers: Organisms that eatprimary consumers (praire felcon, eagle). Decomposers: Organisms that uses nutrients from dead plants and animals, it starts the chain over (bacteria). Say that an organism was removed from the web, such as a caterpillar. Though it's not the only grass eating organism it would still mess up the web. Say you put the bison in its place, that p .....

.... 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, air swirls faster and faster around the storm center. The storm clouds, moving with the swirling air, form a coil. In a .....

.... in charge of all nuclear matters, including weapons research. Other types of bombs were developed to tap the energy of light elements, such as hydrogen. In these bombs the source of energy is the fusion process, in which nuclei of the isotopes of hydrogen combine to form a heavier helium nucleus. This weapons research has resulted in the production of bombs that range in power from a fraction of a kiloton to many megatons. The size of the bomb has been made smaller helping the development of nuclear artillery shells and small missiles that can be fired from portable launchers in the field. .....

.... of dominance-related aggression include an increase in exercise, brushing up on obedience training, and ceasing to engage in any rough play or wrestling (35) . More recently, however, drugs such as Prozac have been used as treatment. Dodman says that Prozac is,"...extremely effective at curtailing dominance-related aggression...enabling owners to quickly gain the upper hand,"(34). Another type of aggression found in canines is seizure-related aggression. Symptoms of seizure-related aggression include a pre-aggression mood change that can last for minutes or hours before a seemingly u .....

.... three quarks distinguished by flavours. Each has a charge that is a fraction of that of an electron. Up and down quarks make up protons and neutrons, and can be observed in ordinary matter. Strange quarks can be observed in omega-minus and other short lived subatomic particles which play on part in ordinary matter(1985 Quarks). The interpretation of quarks as physical entities poses two problems. First, sometimes two or three identical quarks have to be in the same quantum state which, because they have to have half integral spin, violates Pauli's exclusion principal. Second, quarks .....

.... of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. A calorie is the amount of energy needed to raise one gram of water one degree Celsius. If we could efficiently harness the energy bombarding the earth for twenty-four hours we could power New York for a year. Unfortunately the photovoltaic cells that change the energy into electricity are so inefficient that it would take twenty-five years to pay for it's self in output. There many uses of solar .....

.... was then placed into the polystyrene cup and its temperature was taken and recorded using the thermometer. The pre-weighted sodium hydrogencarbonate was then added to the solution, and the final temperature was recorded. The contents of the cup were then emptied out and the cup was washed out with water and then thoroughly dried. This was done three times for the sodium hydrogen carbonate so that I could remove any anomalies that were obtained. The experiment was then repeated in exactly the same manner except sodium carbonate was used instead of sodium hydrogen carbonate. The results wer .....

.... I cannot believe in a being which created a universe and a multitude of worlds in a rather short period of time then deigns to lower itself into becoming a puppet-master and "pulling the strings" of the Earth and all of the people therein. Since this paper touches upon many scientific terms, I feel that in order for the reader to correctly grasp the content I must first define three words: Theory, Law, and Hypothesis. The definitions will allow for a greater understanding of this essay and give us an even ground upon which to begin. Theory; (thÿ1e-rÿ, thÿr1ÿ) noun 1. a. .....

.... competing motives. Freud developed an elaborate theory and how the mind works while asleep. In 1953 sleep researchers led by Nathaniel Kleitman made the important discovery of rapid eye movement--or REM-- sleep. Curious about the long-standing observation that the eyeballs of sleeping subjects in both humans and animals periodically move during sleep, they connected laboratory subjects to equipment that measured their brain waves, muscle tone, and eye movement. About 90% of the time when subjects were awakened during REM sleep, they reported a dream. Prior to laboratory REM research .....

.... ion (Kotz et al., 1996). Other forms of amino acids also exist. Amino acids may exists as acidic or basic salts. For example, if the glycine reacted with HCl, the resulting amino acid would be glycine hydrochloride (see fig. 2). Glycine hydrochloride is an example of an acidic salt form of the amino acid. Likewise, if NaOH were added, the resulting amino acid would be sodium glycinate (see fig. 3), an example of a basic salt form. Fig. 2 Fig. 3 Due to the nature of amino acids, a titration curve can be employed to identify an unknown amino acid. A titration curve is the plot of .....
