A unique inquiry-driven approach helps students dig deep to ask essential questions

• NEW! A three-pronged taxonomy of questions are presented in each chapter to help students pace their learning throughout the course.
  • Section headings and case study sections give students a preview of questions that will be addressed in the chapter.
  • Check Your Learning and End of Chapter questions ask to look back, recall, and reinforce their comprehension of biology concepts.
  • Consider This, Think Critically, Evaluate This, and Applying the Concepts questions ask students to dig deeper, reflect, and think critically about the chapter material
    • NEW!  Think Critically questions challenge readers to apply their knowledge to information presented in a photo, figure, graph, or table.
    • NEW!  Evaluate This questions present a brief, real life scenario and ask the reader to evaluate information before forming an opinion or making a decision.

Engaging Pedagogy encourages student inquiry and critical thinking throughout the text, while relating key topics to the real world

• A Case Study that describes a true and relevant event or phenomenon runs throughout each chapter, tying biological concepts to the real world.
• NEW! Case Studies have been revised and replaced to reflect current events and developments in biology, such as the Ebola epidemic (Chapter 1), DNA Identification (Chapter 8), and Biotechnology (Chapter 14).
• Case Study Continued sections appear within each chapter and expand on the Chapter Opening Case Studies and connect the topic to related biology concepts.
• Case Study Revisited sections appear at the end of each chapter and wrap up the narrative by explaining how the story is related to the biology topics in the chapter. The accompanying Consider This question encourages students to further reflect on the Case Study take-home lessons.
• At A Glance Chapter Outline appears at the beginning of each chapter to give students a handy overview of learning goals for the chapter.
• NEW! How Do We Know That? Essays explore the process of scientific discovery, experimental design, and exciting new biotechnology techniques, explaining how scientists know what they know about biology.
• Boxed Essays in each chapter expose students to biology-related events that occur in everyday life.
  • Earth Watch boxes are presented twice in each unit and adapted to encourage more critical thinking. A question feature will be added to each box to challenge students to think deeply about what they’ve just read.
  • Health Watch boxes with Evaluate This questions ask students to think critically about a real world scenario, connecting key biology concepts to students lives.
• Have You Ever Wondered? questions ask a biology-related question about an everyday curiosity, along with a brief, scientific answer.  Examples include “Have You Ever Wondered..?” Why Bacteria Die When You Take Antibiotics (Chapter 5), If Extinct Species Can Be Revived by Cloning (Chapter 18), and How Big Your Carbon Footprint is (Chapter 29).
• In Greater Depth sections provide deeper coverage of selected topics including the Hardy-Weinberg Principle, Logistic Population Growth, and Hormonal Interactions that Control the Menstrual Cycle.

Reorganisation of chapter topics improves student comprehension

• NEW! Mitosis and Meiosis are now covered in separate chapters, making these topics more manageable for instructors and students.  
• Chapter 9 now covers only mitotic cell division and the control of the cell cycle.  
• Meiotic cell division and its importance in sexual reproduction are now discussed in Chapter 10.

NEW! Improved Figures and Photos appear throughout the text and effectively illustrate biological concepts and processes.

• NEW! Numbered Steps break down complex biological processes into manageable steps.
• NEW!  Think Critically questions challenge readers to apply their knowledge to information presented in a photo, figure, graph, or table.
• NEW!  Clearer, more vibrant colors make it easier to distinguish among different structures.
