The Tenth Edition helps students develop a deeper understanding of biology by making connections visually across chapters and building the scientific skills needed for success in upper-level courses. New Make Connections Figures pull together content from different chapters visually, helping students see Obig pictureO relationships. New Scientific Skills Exercises in every chapter use real data to build key skills needed for biology, including data analysis, graphing, experimental design, and math skills. New examples show students how our ability to sequence DNA and proteins rapidly and inexpensively is transforming every subfield of biology.
