This comprehensive introductory textbook covers biology traditionally - from the structure and function of the cell to the organization of the biosphere. The new 11th AP Edition of Biology features integrated coverage of the new AP Biology Curriculum Framework with Part Openers that provide an overview of the Big Idea as it relates to the chapters within the Part. In addition, each chapter begins with a guide to Following the Big Ideas and concludes with a Connecting the Concepts with the Big Ideas section. The preface includes information on the AP Biology course, the AP Exam, and an AP Correlation, while a complete AP Practice Exam can be found in the back of the book. An icon of science education, Sylvia Mader's dedication to her students, coupled with a concise writing style, has benefitted the education of thousands of students. The integration of this classic text and the digital world is now completed with the addition of Dr. Michael Windelspecht's expertise in the development of digital learning assets. He has acted as the leading architect in the design of the accompanying media content for McGraw-Hill's Connect Plus and LearnSmart. These assets allow teachers to easily design interactive tutorial materials, enhance online and traditional presentations, and assess the learning objectives and outcomes of the course.
