Extremely basic with inconsistant layout. Entire sections will be printed with a blue background, for example, that look more like a special topics box then text. In several cases the text reuses its stock photos in several unrelated sections. The text illustrates points that clearly do not need illustration (Do you know what water looks like? There is a photo of it if you need it. ) and ignores others (the beta and alpha linkages of glucose) after dicussing them. Good for high school student concepts but unacceptably uncomprehensive for college.
