Review for Bio 130: Exam #1

Ok, I know most of you hate lists, but all of you want an idea of what will be on the first exam.  I have listed below all of the possible topics that will be covered in the exam.  I will try to ask a question from each of these topics.  Yes the exams are long but you can do it if you pace yourself.   The fexams are typically 50 multiple choice,  25 matching questions, and one longer essay question.  The topics of these questions are listed below.  If you draw a blank on these questions, please feel free to list this question on the class bulletin board, (A link to the bulletin board will be provided) where you can earn class participation credit by asking this question, or you can earn even more (10pt) by answering one of these questions.
