This title is a Pearson Global Edition. The Editorial team at Pearson has worked closely with educators around the world to include content which is especially relevant to students outside the United States.

This package includes Mastering Biology.

Develop and Practice Science Literacy Skills

Teach students to view their world using scientific reasoning with Campbell Essential Biology*.* The authors approach equips your students to become better informed citizens, relate concepts from class to their everyday lives, and understand and apply real data, making biology relevant and meaningful to their world and futures.

The new edition incorporates instructor feedback on what key skills to highlight in new Process of Science essays and uses striking infographic figures in conveying real data to help students see and better understand how science actually works. New author-narrated Figure Walkthrough Videos guide students through key biology concepts and processes.

New topics in Why It Matters inspire curiosity and provide real-world examples to convey why abstract concepts like cell respiration or photosynthesis matter to students. This edition s unmatched offering of author-created media supports students in the toughest topics with 24/7 access through the enhanced Pearson eText, embedded QR codes in the print text, and Mastering Biology.

Reach every student by pairing this text with Mastering Biology

Mastering is the teaching and learning platform that empowers you to reach every student. By combining trusted author content with digital tools and a flexible platform, Mastering personalizes the learning experience and improves results for each student.

Mastering Biology should only be purchased when required by an instructor. Please be sure you have the correct ISBN and Course ID. Instructors, contact your Pearson representative for more information.
