BIS 2A: Introductory Biology
Marc Facciotti · University of California, Davis
BIS 2A concentrates on the cellular basis of life, concentrating on the structures and functions of cells and the biological molecules from which they are formed, the ways by which cells acquire, transform, and use chemical energy, and the mechanisms by which genetic information is stored, safeguarded, transmitted from one generation to the next, and used in reproduction and development, with the immune systems serving as a example of complex eukaryotic development.

Biology
John W. Kimball · Tufts University & Harvard University
Biology is the study of life, from the molecules inside cells to the diversity of organisms and ecosystems. This book begins with the chemical and molecular basis of life, then explores how cells function, use energy, and transmit genetic information. It also examines how organisms develop, evolve, and interact with their environments, and introduces key tools in biotechnology, medicine, and scientific research. Together, these units offer a concise overview of how life operates at every level.

Fundamentals of Biology Lab Manual
Karen Marks and Valeria Hochman Adler · College Coalinga
Marks and Hochman Adler started developing their OER lab manual for Introduction to Biology when they became frustrated with the paid options and wanted equitable options for their students. Both Marks and Hochman Adler are trailblazers in their field when it comes to accessibility for their students. This lab manual was created in two years with end user testing with students to find what worked and didn't work. This final product is for the students.
