Biology sets the standard for clear, accessible writing and content that engages every student at every learning level. A new focus on the Big Ideas of biology sets the stage for active inquiry and participation. In addition, there is built-in reading support that helps students master concepts. Biology has visual and interactive overviews of complex processes, which aid understanding, add realism and interest, and provide students with a visual link to the narrative. Students read, see, and ultimately understand the fundamentals of biology.
