Textbook Question
Chapter 3.5, Problem 1CC
When water and oil are added to a test tube, the two liquids form two separate layers (think of oil and vinegar in a bottle of salad dressing). If a solution of phospholipids was added to a mixture of water and oil, where would the phospholipids dissolve?

You're an undercover biological weapons agent who has been given an unknown liquid. 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 cloudy white.
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 gelatin, predict what color you expect it to become: [a] (no change | blue | purple).
QUESTION 2
You included both a positive and negative control for this experiment. The water is the [c] control.
QUESTION 3
If the positive control turns purple, it means:
there is no protein present
O this control is no good - need to troubleshoot and perform the experiment again
there is…
