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:

Explain why an animal’s diet should be balanced and meet the needs of the body
Define the primary components of food
Describe the essential nutrients required for cellular function that cannot be synthesized by the animal body
Explain how energy is produced through diet and digestion
Describe how excess carbohydrates and energy are stored in the body

In this course we will explore topics from disciplines within the solid Earth sciences. In each lesson, we'll also touch on some ways the topic links to other scientific disciplines. Each unit is designed to present both the cutting-edge science as well as the background a secondary-school student (or her teacher) would need to place the research in context. Gaining an appreciation of how scientists choose the subjects they study is as fundamental to Earth science as the discovery of the facts themselves. You will learn appropriate state-of-the-art scientific content relevant to each topic by performing basic data analysis using publicly available data so that you will be able to use the data and lessons in any courses you teach.

The emphasis of this course is to use Trace Element Geochemistry to understand the origin and evolution of igneous rocks. The approach is to discuss the parameters that control partitioning of trace elements between phases and to develop models for the partitioning of trace elements between phases in igneous systems, especially between minerals and melt. Subsequently, published papers that are examples of utilizing Trace Element Geochemistry are read and discussed.
