BIOLOGY 102L PRACTICE QUESTIONS

IN ORDER TO CONSERVE PAPER IN THE BIOLOGY COMPUTER LABORATORY,
The following practice test has been prepared for you to get a general idea of what types of questions you might be expected to answer on your final laboratory exam. The questions included here are probably easier and more general than ones you might see on your actual exam. Only a few questions from each lab exercise have been included.
To take this practice test, write the correct answers to each question on some scrap paper. Then, at the end of the test, you will find the answers. If you miss a few and are unsure why, check with your lab instructor BEFORE you take your lab exam.
