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.

Today GPS is critical to positioning, navigation, and timing. The smooth functioning of financial transactions, air traffic, ATMs, cell phones and modern life in general around the world depend on GPS. This very criticality requires continuous modernization. The oldest satellites in the current constellation were launched in the 1990s. If you imagine using a computer of that vintage today, it is not surprising that the system is being substantially updated. Global Positioning System (GPS) is now a part of a growing international con?text-the Global Navigation Satellite System, GNSS. This course dives into how GPS and other GNSS systems are designed, how they operate, and the impacts they have on spatial analysis and spatially-enabled systems.
