Biology is a science full of terms and concepts that range from the hard-to-imagine, such as the structure of an atom, to those we see every day, such as the structure of our own face in the mirror. How are these ideas and concepts related? What's the best way to learn and remember them? Designed to be used with the class textbook (or in place of the totally incomprehensible one!), Homework Helpers: Biology is a user friendly review book that will make any student-or those trying to help them-feel like he or she has a private Biology tutor. Concepts from the most obvious to the most complex are presented and explained in everyday English with a wide variety of diagrams, charts and illustrations. The Homework Helpers Series is just what students need to boost their confidence and give them the help they need to ace even the most challenging classes.
