Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

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.

A great site for understanding Amino Acids, the building blocks for protein. Besides a very complete summary, the site includes a complete list of amino acids, a link to basic amino acid structure, a list if atoms in amino acids, and links to test yourself. Very informative!

Animal nutrition focuses on the dietary needs of animals—not just those in agriculture and food production, but also in zoos, aquariums, and wildlife management. Pets need good nutrition, too. In this lesson, students compare pet foods. This unit features 3 lessons and 6 files. Lessons are aligned to NGSS.

Create a cookbook to learn Standard Operating Procedures for food safety and environmental monitoring. Test for proteins, carbohydrates, and lipids and compare plant and animal protein. This unit features 5 lessons and 16 files. Lessons are aligned to NGSS.

This STEM-based poultry curriculum uses immersive learning experiences and real genetic samples for your students to dive deep in the future evolution of our food. See how environment influences heredity, and explore the evidence that suggests T. rex as our modern chicken’s and turkey’s ancestor. This unit features 4 lessons and 10 files. Lessons are aligned to NGSS.

A video discussing the molecular structure of DNA. Understand that DNA is made up of a phosphate, deoxyribose sugar, and one of the four nitrogen base. Video also explains how the nitrogen bases pair up to form the double helix structure. Also learn how DNA stores the genetic information for organisms. [13:01]
