We then went to see if the sucrose entered the bag unfortunately the benedict's solution showed negative results. The second test ( Bag: 5% ovalbumin Beaker: 1 M sucrose) we put biuret in a test tube with the beaker solution and the indicator showed negative results. Then for the next test (Bag: 1 M Glucose Beaker: distilled H2O) they put Benedict's solution in a test tube with the beaker liquid. The benedicts showed positive results. The next test (Bag 1 M Sucrose Beaker: 1 M NaCl) they put Benedict's solution in a test tube with the beaker liquid. The indicator showed negative results. For the next test(Bag: 1 M NaCl Beaker: distilled H2O) they put silver nitrate in a test tube with the beaker liquid. The silver nitrate showed positive results. The next test (Bag 1 M sucrose Beaker: 5% ovalbumin) they used mass change to determine if the solute could pass through the bag. They weighed the bag before and after. The mass of the bag decreased showing that the H2O passed through the bag. The next test (Bag: 1 M NaCl Beaker: 1 M glucose) they put silver nitrate in a test tube with the eaker liquid. The indicator tested positive. The next test( Bag 1 M Glucose Beaker 1 M sucrose) they put iodine in a test tube with the beaker liquid. The indicator showed positive results. The next and final test (Bag: 1 M glucose Beaker: 5% ovalbumin)…

Mr. Tony, a biology teacher, gives his student Ziad four samples and tells him they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), and RNA. The samples are in test tubes marked 1, 2, 3, and 4, but Ziad is not told which compound is in which tube. He is asked to identify the contents of each tube.…
