Review

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This 13-minute video lesson provides an overview of glycolysis. [Biology playlist: Lesson 24 of 71].

This 17-minute video lesson looks at oxidation and reduction in cellular respiration. It Reconciles the biology and chemistry definitions of oxidation and reduction. [Biology playlist: Lesson 23 of 71].
