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 how ecologists measure population size and density
Describe three different patterns of population distribution
Use life tables to calculate mortality rates
Describe the three types of survivorship curves and relate them to specific populations

This lesson models how to solve problems involving samples of populations and the variability in the results of a statistical study. Provides a link to an interactive web app called "Sampling Distribution of the Sample Proportion." Includes downloadable study guide with exercises - guide also covers other topics. [9:29]
