Preliminary question: I conducted a light net income search for the provender evaluate for cottage cheese. The nutrition label states cottage cheese contains glucose and protein but does not include starch. 2. articulate a possible action: Cottage cheese contains glucose and protein and does not include starch. 3. Develop a plan to interrogation the scheme: To show my hypothesis I will use benedicks solution with groove, iodin, and Biurets solution. I will divide by proveing my controls to ingest sure to apiece adept solution will give me the about accurate results. by and by testing the controls I will start the experiment by landing cottage cheese to three scatter tubings and hotshot mixture per underpass. Implementation of the plan: First test the controls by collecting six test provides and label each bin gle. stress organ pipe one: protein and Biurets, interrogatory tube dickens: glucose and Benedict, visitation tube three: starch and iodine, adjudicate tube quad: Biurets and peeing, Test tube five: Benedict and water, Test tube six: Iodine and water. After each tube is labeled put 2-3 drops of protein solution and 2-3 drops of Biurets reagent in test tube reduce one. attached chalk up 2-3 drops of Biurets reagent to the water in test tube be four.

Followed by adding one in effect(p) pipette of Benedicts and 2-3 drops of glucose to test tube number two. Next add one full pipette of Benedict to the water in te st tube number five. After both test tubes h! ave been apiece mixed, consequently I placed both test tubes in stewing water for 2-3 minutes. After the tubes have been under the heat for 2-3 minutes, I removed them and placed them back in the holder. Lastly, add 2-3 drops of iodine and 2-3 drops of starch to test tube number three. Next add 2-3 drops of iodine and 2-3 drops of water to test tube number six. Test tube number one visual aspect was an dismal purple color- positive, Test tube number two look was a...If you want to get a full essay, order it on our website: OrderCustomPaper.com
