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:

Identify the two types of root systems
Describe the three zones of the root tip and summarize the role of each zone in root growth
Describe the structure of the root
List and describe examples of modified roots

This course will explore the rich diversity of women's voices and experiences as reflected in writings and films by and about Latina writers, filmmakers, and artists. Through close readings, class discussions and independently researched student presentations related to each text, we will explore not only the unique, individual voice of the writer, but also the cultural, social and political contexts which inform their narratives. We will also examine the roles that gender, familial ties and social and political preoccupations play in shaping the values of the writers and the nature of the characters encountered in the texts and films.
