DNA fingerprinting (or DNA profiling) is the process where a specific DNA pattern or profile is obtained from a biological sample. There are regions that are highly variable between individuals making a DNA profile unique for everyone. The following profiles were generated from blood found at a crime scene from 3 individuals that were people of interest on the investigation. Explain how you analyzed the above DNA fingerprint to obtain the correct answer.

Yeast can ferment a variety of sugars in anaerobic conditions. Carbon dioxide is produced as a byproduct. A respirometer can be used to determine how much carbon dioxide is produced and thus measure rates of fermentation. Respirometers were set up that contained yeast and either a solution containing a carbohydrate or distilled water. The height of the bubble contained in the respirometer was measured every 5 minutes for 20 minutes. The results can be seen in the graph below. Which tube from this experiment is most likely to contain distilled water & yeast?

You create an experimental “cell” by putting a 50% sugar solution into some dialysis tubing (a semi-permeable membrane). Sugar molecules are large and cannot pass through the membrane. If you wanted to make your cell gain weight, which beaker should you add your cell to?
