Written by an accomplished teacher, practicing biologist, and internationally best-selling author, What Is Life? A Guide to Biology was developed to engage students who may never take another biology course—future business owners, lawyers, teachers, poets, etc. Drawing on his extensive classroom experience, Jay Phelan focuses on clearly articulating key concepts and eliminating unnecessary detail and topics—without introducing inaccuracies from simplification. What Is Life? prepares students to talk confidently and knowledgeably about science with their friends, to be intelligent consumers of scientific information, and to make responsible decisions about scientific issues.   Now, What Is Life? A Guide to Biology with Physiology includes chapters on plant and animal physiology.  Visit the What Is Life? preview site at www.whfreeman.com/phelanpreview
