Biology Fall 2015 Mid-Term Study Guide This packet contains the concepts covered this fall in the Biology classes. The concepts are based on the Georgia Performance Standards for Biology. We ask that you work on this for preparation for your final. The content here is not necessarily all-inclusive. Please use any notes, worksheets, and other materials provided throughout the school year to aid your studies. Interactive review: www.classzone.com Chapter 1: Biology in the 21st Century 1.
