You're an undercover biological weapons agent who has been given an unknown Iliquid - you suspect that it was derived from a cacao plant source (it smells like chocolate). One of the tests you need to run is to see if it contains protein (remember, foreign proteins can cause severe immune responses which can be a powerful biological weapon). You set up 3 test tubes each with 10mL of the following: distilled water, gelatin solution and the unknown. The distilled water is clear, the gelatin solution is clear with a beige tint, and the unknown is clear with a faint tint. green You use Biuret's Reagent - a dark blue dye which will turn a liquid sample purple in the presence of protein. When Biuret's Reagen is added to the unknown, predict what color you expect it to become if the unknown was derived from a cacao plant source: [a] (no change | blue | purple). purple You included both a positive and negative control for this experiment. The gelatin is the [c] control. negative If the negative control turns purple, it means: there is no protein present this control is no good - you need to troubleshoot and perform the experiment again O there is protein present this control is doing exactly what its supposed to do - you can have confidence that the results of the unknown will be accurate
