...Self-motivation has a different meaning to everyone. Literally, the definition of self-motivation is: motivated to do or achieve something because of one’s own enthusiasm or interest, without needing pressure from others. In the novel The Color of Water, written by James McBride, he delineates self-motivation as, “The constant learning and yearning for knowledge…” (pg. 270) James McBride’s view on self-motivation is emphasized through his use of rhetorical terms such as: tone, parenthetical, point of view, and many other rhetorical terms. The attitude of a writer toward the subject or audience is helpful in identifying said writer’s views. In this case, views on self-motivation are being identified. James McBride’s tone in The Color of Water can be described as matter-of-fact. As James describes things his mother, Ruth, does in her retired years he states, “But that’s not enough to keep her busy.” (pg....

...In the story of Color of Water, Ruth and James both dealt with their grief over Hunter Jordan’s death similarly; both of them having in common of dealing with their grief of it making them unaware of what is occurring, not having a care. As you can see, “blacks and whites who disliked her for being a white person in a black world. She saw none of it,” (McBride 8), Ruth was unaware of the danger she could’ve faced, because whites and blacks did not like her for being a white person in a black neighborhood. Another example of how Ruth dealt with her grief was riding “in slow motion across...Murdock...only white person in sight,” (McBride 7). Ruth’s way of dealing with her grief was by distracting herself, that being outside, enjoying nature...

...CHAPTER I INTRODUCTION Candies are ideal choice when your product requires exceptional color, aroma, or flavor quality. Most commonly, candies are hard molded sugar that may be presented by designated forms or shards with highly concentrated color and rich flavor. On the other hand, tomato (Lycopersicum Esculentum) is a common name for a perennial herb. It belongs to the nightshade family, Solanaceae, and for its edible fruit. Botanically, the tomato is a fruit, but for purposes of trade it is classified as a vegetable. Because tomatoes are warm-season plants and sensitive to frost, they are grown as annuals in temperate climate. Tomato is a red fruit which is rich a good source of collagen. It is also an excellent source of vitamins A and C, lycopene which is a natural antioxidant, and potassium. The tomato is also used medicinally. The pulp and the juice are digestible, mild aperients (laxative), promoter of gastric secretion, and a very good blood cleanser or purifier. They are considered as an intestinal antiseptic, useful in cancer of the mouth, for sore throat. It stimulates a turpid liver, and is good for dyspepsia. It is highly prescribed for case of biliousness and it promotes the flow of bile. The juice is recommended for asthma, bronchitis, and those who have tuberculosis. One doctor says: “Tomatoes have the richest vitamins of all foods; they are the most wonderful blood cleanser of all foods known to man; the richest of all vegetables with their...

...Intro This method is used for the determination of ammonia nitrogen in drinking water, ground water, surface water, and domestic and industrial wastes according to USEPA Method 350.1 and Standard Methods 4500–NH3 H. Prior to analysis, ammonia is buffered to pH 9.5 and distilled into a solution of boric acid. Cyanate, which may be encountered in certain industrial effluents, hydrolyzes to some extent, even at the pH of 9.5 at which distillation is carried out. #Distillation - adding excess base to the acid digestion mixture to convert NH4+ to NH3, followed by boiling and condensation of the NH3 gas in a receiving solution. #Titration - to quantify the amount of ammonia in the receiving solution. #The amount of nitrogen in a sample can be calculated from the quantified amount of ammonia ions in the receiving solution. The DistillationProcess The acid digestion mixture is diluted and made strongly alkaline with NaOH, liberating NH3 as follows: (NH4)2SO4 + 2NaOH ➝ 2NH3↑ + Na2SO4 + 2H2O Ammonium sulphate heat gas ammonia The Kjeldahl flask is attached to a water condenser and is heated to boil off the NH3 gas from the digest. The tip of the condenser is submerged in a flask of acidic receiving solution, either standard acid or boric acid solution, to again trap the distilled NH3 in receiving solution. NaOH Addition Concentrated NaOH (usually 50% solution) is added slowly...

...ABSTRACT Water pollution poses great threat to human health. Because of this, natural filters are recommended for use. This study evaluated the potential of corn cobs as an alternative filter material in the removal of impurities in water by measuring the flow rate, pH level and the color of the filtered sample. The corn cobs were grinded and activated using water and vinegar with the ratio of 1:3 and served as the alternative filter material. The activated carbon were placed in a transparent tube at varying thickness and served as treatments T1 (0.5 inch), T2 (0.75 inch), T3 (1 inch), and T4 (control). Results showed that T1 has the fastest flow rate, T3 has the highest pH level and lightest color. Statistical analysis showed that there is a significant difference on the flow rate among the four samples. The pH level among T1, T2 and T4 are not significantly different with each other but significantly different with T3. These lead to conclusion that the flow rate increases as the thickness of the filter material decreases. On the other hand, the pH level and the lightness value increases as the thickness of the filter increases Key words: corn cobs, activated carbon, filter, flow rate, pH level ACKNOWLEDGEMENT The researchers would like to express their gratitude and appreciation to the following: Mrs. Felerma G. Urbano, their research adviser, for the patience, moral support and encouragement she gave to keep moving even if the work was hard. Sir. Edgar Flores...

...separation from the solution. This separation is done in a particular sequence because some ions of prior groups can also react with the reagent of later groups. This can be cause of difficulty in their separation. The qualitative analysis of cations depends on the solubility products of the ions. The cations get precipitated on the optimum needed concentration and easily detected. 1st group of cations The group (I) cations form the insoluble chlorides. The dilute hydrochloric acid (generally 1-2 M concentration) is used as the group reagent. The Concentrated HCl is not used because it forms a soluble complex ion ([PbCl4]2-) with Pb2+ and would not be detected. The most important cations of 1st group are Ag+, Hg22+, and Pb2+. Color detection test is not suitable for their chlorides because all are white solid compounds. The analyzing of group is done by adding the respective salt into water and follow it with dilute HCl. This results in a white precipitate in which NH4OH is added. The insoluble precipitate shows the presence of Plumbous (Pb2+) and if precipitate is soluble, then it shows the presence of Argentous (Ag+).If the white precipitate turns black, it shows the presence of Hg22+. The obtained filtrate after first group analysis is used for the test of second group. Usually Pb2+ is also included in the 2nd analytical group because the solubility of PbCl2 is more than the chlorides of other two ions. Confirmation Test For lead Pb2+ + 2KI → PbI2 + 2...

...Effects of Vitamin Water on Peroxidase Activity Levels in Radishes Abstract: In this experiment, two radishes were treated with almost all factors the same; they received the same amount of sunlight and were watered at the same time. However one radish, the control, was watered with regular water and the other radish with Vitamin Water. It was hypothesized that the radish that had been watered with Vitamin Water would have higher peroxidase activity levels because it was under more stress than the plant that was watered with water. Through the use of such techniques as tissue prints, dot-blot assays, electrophoretic analysis, and spectrophotometric assays, peroxidase activity levels were visualized and quantified. The results were as expected; the tissue from the plant that had been treated with Vitamin Water was more purple on the tissue prints and it was spectrophotometrically determined that the plant that had been treated with Vitamin water had a higher amount of peroxidase activity than the one that was treated with water. The results proved that the hypothesis was correct; stress on a plant, Vitamin Water in this case, causes higher levels of peroxidase activity. Introduction: Peroxidases are enzymes that use hydrogen peroxide as an electron acceptor to catalyze oxidative reactions. Peroxidase is believed to play a major role in synthesizing cell walls, preventing toxins and responding to stress. It is responsible for the purple color that is seen throughout the experiments...

...test is used to determine the concentration of dissolved oxygen in water samples. Dissolved oxygen (D.O.) is widely used in water quality studies and routine operation of water reclamation facilities. An excess of manganese(II) salt, iodide (I–) and hydroxide (OH–) ions is added to a water sample causing a white precipitate of Mn(OH)2 to form. This precipitate is then oxidized by the dissolved oxygen in the water sample into a brown manganese precipitate. In the next step, a strong acid (either hydrochloric acid or sulfuric acid) is added to acidify the solution. The brown precipitate then converts the iodide ion (I–) to iodine. The amount of dissolved oxygen is directly proportional to the titration of iodine with athiosulfate solution.[1] Today, the method is effectively used as its colorimetric modification, where the trivalent manganese produced on acidifying the brown suspension is directly reacted with EDTA to give a pink color.[2] As manganese is the only common metal giving a color reaction with EDTA, it has the added effect of masking other metals as colorless complexes. History The test was originally developed by Ludwig Wilhelm Winkler, in later literature referred to as Lajos Winkler, while working at Budapest University on his doctoral dissertation in 1888.[3] The amount of dissolved oxygen is a measure of the biological activity of the water masses. Phytoplankton and macroalgae present in the water mass-produce oxygen by way of photosynthesis. Bacteria and eukaryotic...

...even in situations where no other light is available. Artificial lights allow regular people to plant whole gardens in places where no plant would ordinarily grow. A lesson in cell metabolism-energy and photosynthesis mentions that “chlorophyll absorbs most red, orange, blue, and violet light. It reflects green and yellow light, giving its body a green coloring”. This statement got the researchers curious and wondered if plants act differently to the green and yellow colors of light, then they should have different reactions and effects to every color of light. (Capco C., Yang G., 2010). This study aimed to find if there exist a significiant difference in the growth of plants when exposed to different colors of light specifically red, yellow, green, blue, and white. In this case, the researchers chose the mongo plant since it grows quickly and the researchers can quickly gather the needed data immediately. B. Statement of the Problem This study determined and compared the effect of different colors of light on the growth of mongo plants. Furthermore, it addressed the following...

...Enzymatic Reaction of Sucrose and Sucrase: Analysis Under Different Conditions and Concentrations Abstract: Sucrase is the enzyme that breaks down sucrose into glucose and fructose. The purpose of this lab experiment was to determine under what environment the enzymatic reaction between sucrose and sucrase would produce the most products and the rate of production. To determine the rate of reaction, Benedicts Reagent was used to identify the amount of glucose produced from the enzymatic reaction. Benedicts Reagent is used to detect the presence of glucose and indicates the results with varying degrees of color. We were successful in our endeavors to measure this rate of reaction with Benedicts Reagent and conclude that the higher the substrate or enzyme concentration, the faster the rate. The process of using Benedicts Reagent to measure glucose levels is also used in urine analysis for people with diabetes. Introduction: All living organisms need to supply themselves with nutrients and as humans, we use the process of digestion to break down and extrapolate the nutrients from our food to maintain and fuel our bodies. In order to perform digestion our bodies use enzymes, which are biological catalysts. They are made of proteins that responsible for the chemical reactions essential to sustaining life. Enzymes have three major characteristics: increase the rate of reaction, are substrate specific and lower the energy barrier it takes to for reactants to occur...
