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.

By the end of this section, you will be able to do the following:

Describe prions and their basic properties
Define viroids and their targets of infection

This textbook has evolved from online and live-in-person lectures presented in Professor Kenneth Todar's bacteriology courses at the University of Wisconsin-Madison. Its contents are suitable for reading or presentation in courses or course modules concerning general microbiology and medical bacteriology at the college and advanced high school levels of education. For teachers, instructional materials are available that accompany many chapters and topics. These include lecture outlines, notes, powerpoint presentations, and examination questions that compose a study guide
