Bio. 2100 – Biology for Non-Majors – Dr. Eric Schwartz

Topics to Review for Exam 1

To properly prepare for the exam please review your notes on each topic listed below. If you are not confident that you fully understand a topic, go back and read the text book on that topic. If you are still unclear on a topic please ask me to explain what you don’t understand. Asking me in person is the most efficient way for me to be able to explain something to you and be certain that you understand my response. You may certainly e-mail me questions that you may have and I will make every effort to respond to your e-mails as soon as possible. However, please realize that an e-mail response can’t be as in-depth as an in person explanation. Also, I may not be able to respond to your e-mail immediately so if you e-mail me right before an exam I may not be able to get back to you in time for the exam.
