I will dissociate by mental testing my controls to ingest sure to apiece star solution will give me the about accurate results. later on testing the controls I will start the experiment by landing cottage cheese to three scatter tubings and virtuoso mixture per underpass. Implementation of the plan: First test the controls by collecting six test subway-shaped structu res and label each one and only(a). rill tube one: protein and Biurets, canvass tube dickens: glucose and Benedict, shew tube three: starch and iodine, try tube quartet: Biurets and water supply, 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 cast up 2-3 drops of Biurets reagent to the water in test tube routine four.

Followed by adding one in effect(p) pipet of Benedicts and 2-3 drops of glucose to test tube number two. Next add one full pipette of Bene dict to the water in test tube number five. ! After both test tubes have been apiece mixed, and so I placed both test tubes in boil 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.
