BIOLOGY: LIVING SYSTEMS is a systems approach to the major concepts of biology. The text narrative presents relationships among major concepts that establish a thematic approach that links together ideas from one chapter to the next. Connections and applications emphasize the relationships between biology and other disciplines. Opportunities for learning by doing provide for increased student comprehension and development of critical thinking skills. This program can be used as a first or second year course in biology. (This is not an advanced placement course.)
