A COMPARATIVE ANALYSIS OF THE THEORIES ON NATIONALISM‚ FOCUSING ON THE THEORIES OF BENEDICT ANDERSON AND PAUL BRASS. Submitted by: A. B.Tekkethil M.A Sociology- III Semester. Human beings‚ in any given interaction with each other‚ attach to themselves and others various identities. This way‚ based on the situation‚ one can attach multiple identities to oneself‚ ranging from gender‚ religion‚ caste‚ class etc. In a survey of this kind today‚ one will find that the nationality of a person is

with the Bluret reagent should come out positive for being a protein. The pepsin in the Bluret reagent should be positive and should be a protein. The test for sugar in the Bluret reagent should be negative and I don’t think it is a protein. The test with the distilled water with the Bluret reagent should be negative and is not a protein. In the second experiment to test for glucose with the Benedict reagent sugar should be positive for glucose. Starch mixed with the Benedict reagent is probably

Title: Benedict ’s test for Reducing Sugars Testable Question: Are all carbohydrates reducing sugars? Hypothesis: If the carbohydrate contains available ketone or aldehyde molecules then they are reducing sugars. Variables: a. Independent: Function groups react w/ reagent b. Dependent: Color change (red‚ orange‚ yellow) Control: Water Materials: - 4 mL of each solution (Water‚ Starch‚ Glucose‚ Maltose‚ Sucrose‚ Onion Juice‚ Potato slice‚ Milk) - 8 test tubes

test tubes. Tollen’s test In three test tubes‚ 1 ml of Tollen’s reagent was placed separately. To one tube‚ a drop of formalin was added; to the other‚ a drop of acetone was added; and to the other a drop of benzaldehyde was added. The solutions were mixed thoroughly. Since there was no reaction at room temperature‚ the solutions were placed in hot water bath . Schiff’s test In three test tubes‚ 5 drops of Schiff’s reagent was placed separately. To one tube‚ a drop of formalin was added‚

If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter‚ then it will turn. If iodine is added to starch‚ then it will turn. If Benedict color is added to apple juice‚ then it

bloodstream. The experiment will be performed by adding amylase to starch solutions under varying conditions of temperature and pH. After an appropriate time‚ the solutions will be tested for the presence of sugar. By adding Benedict’s reagent to the various solutions‚ the presence of sugar will be determined depending on colour change. No colour change after several minutes mean no sugar is present. Ultimately‚ the affects of temperature and pH of digestion of starch will be

B‚ C and D. Research Question: Out of the four given samples which sample consists of protein/ starch/reducing sugar/ disaccharide? What color changes will help to identify the contents of each sample when treated with iodine‚ biuret agent and benedicts solution? Theory and background information: What is a protein?1 Proteins are macromolecules‚ consisting of one or more chains of amino acid residues. Proteins perform a vast array of functions within living organisms‚ including catalyzing metabolic
