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.

Paul Andersen explains how water quality can be degraded by pollutants. Wastewater is the main source of water pollution and can be measured using the BOD (biochemical oxygen demand). Dead zones, cultural eutrophication, disease, and other pollutants are included. A 'Water Pollution Concept Map' is also available for download. [9:07]

How does the production of corn affect water quality? How is water quality tested?

Corn production's impact on water quality has improved due to best management practices, reducing sediment and nutrient losses significantly. Modern agriculture uses genetically modified crops and efficient water infiltration methods, alongside USDA programs and the 4 Rs nutrient strategy, to lessen environmental impact. Water quality is assessed through chemical tests measuring properties like dissolved oxygen and nutrients, essential for aquatic life. Biological assessments, based on vertebrate and macroinvertebrate diversity, indicate water health, reflecting the ecosystem's chemical and physical condition. Riparian zone management, affecting stream structure and temperature, plays a crucial role in maintaining water quality, highlighting the interconnectedness of agricultural practices and aquatic ecosystems.
