Whitney East Mr. Beall Speech 1200 October 24‚ 2012 Outline: Topical Classifying Fish Specific Purpose: To inform my audience about the different classifications of fish. Central Idea: Fish are classified by their different characteristics which sorts them into different classes like Agnatha‚ Chondrichthyes‚ and Osteichthyes. Introduction I. Classification of living things helps people to understand how living organisms may or may not be related to each other. A. The system of classification

Facts of the periodic table While Dmitri Mendeleev is most often cited as the inventor of the modern periodic table‚ his table was just the first to gain scientific credibility‚ and not the first table that organized the elements according to periodic properties. There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made. Technetium was the first element to be made artificially. The International Union of Pure Applied Chemistry‚ IUPAC‚ revises

I am a fish‚ very small and cute. At one time a long long ago‚ I used to live in the depths of a river but‚ as time passed by‚ my life has changed a lot. This new life that I am spending now‚ is just wonderful‚ and I like it immensely. However‚ life was never hard on me. Even when I lived in the river‚ I was very happy as‚ life there was calm and quiet‚ and I gained a lot of experience there. Going backwards down memory lane‚ I can very clearly recall my life in the river. There‚ in the depth of

The goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus

Fish Schooling Abstract This experiment tested schooling behaviors between two species of fish. The fish used to conduct the experiment were Zebra Danio fish and minnows. The number of fish required for schooling and elapsed time was also accounted for. The results showed that mixed-species schooling may occur. The numerical quantity and time also proved to be a factor in the experimental results. Introduction A fish school is another word for a large unit of many fish which congregate

Next to oxygen‚ water is the second most crucial necessity of human life. Up to 60% of the human adult body is water (Perlman). Human blood is made up of ninety-two percent water (Sanders). The relevance of ingesting water is the cause for a debate about which source is the best‚ bottled water or tap. There are several reasons to choose bottled water over tap water when quenching thirst. One reason to choose bottled water rather than tap water is because bottled water is odor free. Occasionally
