Metabolizer phenotype of CYP2D6

I got 0 out of 15 points for my answer on this problem. I'm thinking I should have received some partial credit. I'm posting the original question, my answer, and the "official" answer. I understand that the given answer is a better method, but won't my proposed method work? I'm looking for some expert, detailed, technical advice to help me support my claim for partail credit. The Problem: Briefly describe the method that you would use to test an individual for metabolizer phenotype of CYP2D6. Be sure to include the name of the test compound, when and which biological fluid(s) to collect, which compound(s) to measure, and how to assess metabolizer phenotype.

Partial pressures of gases in blood

When our professor was teaching this subject she kept refferring to how this correlates to atmospheric pressure. Others in the class and myself asked her to be more specific but, it did not help. Can this be explained a little better, just how does pressure of gases in blood correlate with atmospheric pressure? Can you explain Henry's law a bit better--I'm a bit confused? Thank you

Pathophysiology

Please could you answer these questions as true or false (also attached): 1. An increase in tissue oncotic pressure contributes to edema. 2. Heart failure is an example of a disease state that causes generalized edema. 3. Hypertonic fluid alterations occur when the osmolality of extracellular fluid is below normal. 4. Plasma oncotic pressure is determined by the concentration of colloids. 5. Pooling of blood in the veins causes increased capillary hydrostatic pressure. 6. Water balance is closely related to sodium balance. 7. Secretion of aldosterone results in decreased blood volume. 8. Hyperkalemia causes cardiac arrhythmias. 9 Compensation for... click for more

APA and APS on the World Wide Web, Empirical Research

Part 1 1.What do the following examples show us about the need for empirical research? Provide not only your answer to each question, but your rationale for your answer. a. If you drop a bullet off a 3-foot-high table, and fire another one straight across an empty football field, which will hit the ground first? b. A ball rolls down a spiral track. The end of the track curves left. What path will the ball take when it leaves the track? c. A wooden cube is 1 inch long on each side. How many cubes will you need to form a cube that is 2 inches along each side? 2. What are two of the costs associated with using deception in psychological research? What are two of the benefit... click for more
