3. Explain what caused the change in plasma ketone concentration over the course of the experiment.
III: My group had the geography map. Which was based off of elevation, so we had determine the highest and lowest points of theses plate tectonics. First, we observed all of the boundaries and determined the differences. Once we found some differences, we had to determine

The vials were placed in the water and the oxygen levels were read every 5 minutes until 30 minutes was reached. As the oxygen levels were collected they were put into a table that had all three tubes labeled at each 5-minute increment. After 30 minutes the experiment was completed and the clean up process could begin.
7.The air dried filter paper was then placed on the weighing scale and results were recorded
