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 angiosperms are the dominant form of plant life in most terrestrial ecosystems
Describe the main parts of a flower and their functions
Detail the life cycle of a typical gymnosperm and angiosperm
Discuss the similarities and differences between the two main groups of flowering plants

Subject has three goals: introduces students to the classic works on ethnic politics, familiarizes students with new research and methodological innovations in the study of ethnic politics, and helps students design and execute original research projects related to ethnic politics. Readings drawn from across disciplines, including political science, anthropology, sociology, and economics. Students read across the four subfields within political science. Graduate students specializing in any subfield are encouraged to take this subject, regardless of their previous empirical or theoretical background. Subject designed as a year-long research workshop, but may also be taken in either semester. This course is designed mainly for political science graduate students conducting or considering conducting research on identity politics. While 17.504 Ethnic Politics I is designed as a primarily theoretical course, Ethnic Politics II switches the focus to methods. It aims to familiarize the student with the current conventional approaches as well as major challenges to them. The course discusses definition and measurement issues as well as briefly addressing survey techniques and modeling.

This course explores how identities, whether of individuals or groups, are produced, maintained, and transformed. Students will be introduced to various theoretical perspectives that deal with identity formation, including constructions of "the normal." We will explore the utility of these perspectives for understanding identity components such as gender, sexual orientation, race, ethnicity, religion, language, social class, and bodily difference. By semester's end students will understand better how an individual can be at once cause and consequence of society, a unique agent of social action as well as a social product.
