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:

Classify the different types of joints on the basis of structure
Explain the role of joints in skeletal movement

Contains plans for three lessons that teach students to express and perform responses to reading. In addition to objectives and standards, this instructional plan contains links to PDF handouts and sites used in the lessons as well as assessment and reflection activities.

This lab video demonstrates how to perform a PCR (Polymerase Chain Reaction) in the laboratory setting.

Brush up on your reading comprehension skills when you check out this website. It looks at a particuar strategey called QAR. QAR stands for "Question-Answer Relationships." This particular strategy helps students learn to answer reading comprehension questions.

Students learn why shock absorbers are necessary on vehicles, how they dampen the action of springs, and what factors determine the amount of dampening. They conduct an experiment to determine the effect of spring strength and port diameter on the effectiveness of a shock absorber. Using a syringe, a set of springs, and liquids of different viscosities, students determine the effects of changing pressures and liquids on the action of a model shock absorber. They analyze their data through the lens of an engineer.
