BIOL 213. Practice Exam.
You should be familiar with ALL the techniques used in the lab. Remember that your final will be
mostly practical. This means you will be using the techniques/instruments to measure/observe
different metrics.
When studying for this exam, strive to understand the purpose/application of each lab instead of simply
memorizing the answers. Key study questions are:
oWhat are we studying in this lab? Why? What do we want to accomplish? Ex. To know
the concentration of protein in my solution.
oWhat are the variables involved? What is the metric used?
oWhat are the techniques involved? Why are we using this technique?
oWhat is your positive and negative control in each experiment? What does each of them
contain?
oWhat are the key definitions?
1. Using the diagram of the electromagnetic spectrum determine the color of the pigments in the
following graph. Why there is no absorption at ~ 525nm?
2. If you want to transfer 7 ml of water into a test tube. What pipette would you use? And for
15ml? Check the use of pipettes to transfer different volumes.
3. A sample is in focus at high dry under the microscope. What is the total magnification? Check
the use of the microscope, how to operate the instrument to high dry.
