starch is hydrolyzed and green-blue solution is formed at test tube 4. Hydrochloric acid actives in high temperature but not room temperature. Hydrochloric acid hydrolyzes starch into glucose at high temperature of 95°C in order to show positive Benedict test. At temperature of 37oC‚ hydrochloric acid may show a little or no reaction on starch as starch is not reacted at optimum temperature or the reaction is low. As the time of heating increases‚ the amount of starch that hydrolyzes by the enzyme

sent to DePauw University at Greencastle Indiana in 1919‚ where her intention was to major in English. Unfortunately‚ Margaret was looked down on in DePauw‚ so she transferred to Barnard College where she studied with Franz Boas and his student Ruth Benedict. It was also at Barnard College that she decided to make anthropology her main field of study. She received her B.A. degree from Barnard in 1923. In September of that same year‚ Margaret was married to Luther in a small Episcopal Church where she

The general idea of a detention is major trouble. I don’t like getting into trouble. It makes me feel uncomfortable‚ and I loathe being yelled at and getting humiliated in the middle of a class. I am that kid who is passionate about the actor‚ Benedict Cumberbatch. I know all of the lines of the movies Cumberbatch is in. This summer‚ I went on a Sherlock Tour in London and experienced the places Cumberbatch was in. I have a life-size poster of Sherlock and a calendar of Cumberbatch in my room.

Bullying behavior seems to have been documented in the scientific research of anthropologists. Ruth Benedict notes in her mid-20th century research on the Japanese‚ and Canadian anthropologist Richard Lee notes in his contemporary research on the Ju/’hoansi‚ that children in other cultures can play in ways that sound like bullying.

felt that the capture of the British Fort Ticonderoga was essential. The once mighty fortress was slowly crumbling into pieces‚ but it was thought that it could be used as a base. Once given finacial support from Connecticut‚ Allen gained news that Benedict Arnold of Massachusetts‚ had also been told to capture the fort. Against their better judgements‚ Allen and Arnold formed an aliance in order to capture the fort. On May 9th of 1775‚ Arnold and Allen succeeded in capturing Ft. Ticonderoga and later

“Use of Biuret Reagent to Test for Proteins In Food” Cindy Zhou Introduction Protein is a series of amino acids that are connected together by peptide bond. The bond is located between the end of previous amino acid‚ which is the carboxyl group‚ and the head of next amino acid‚ which is a amino group. The Biuret reagent is a solution of copper sulfate and potassium hydroxide. When peptide bond are presented‚ the copper (II) will interact with them (MadSci Network: General Biology). It is

Copper-Silver Nitrate Reaction Introduction In this experiment copper wire will be placed in a solution of silver nitrate. This single replacement reaction will produce a blue solution of copper II nitrate and solid silver. By weighing the reactants before the reaction‚ the mass of silver produced can be predicted. This theoretical yield can be compared to the actual yield of silver. Purpose Students will compare the theoretical mass of silver with the actual mass of silver from the single
