SCB 115 Course Description

This is a one-semester laboratory-based course in biology stressing general concepts and amplifying them through a study of the human organism. The scientific method of thinking will be emphasized. Topics will include biological chemistry, cell structure and function, classical and molecular genetics, evolution and ecology, and homeostasis will be explored in the context of human biology. Laboratory exercises will include chemical analyses of nutrients, microscope slides and dissection of the fetal pig. Prerequisites: CSE099, ENG099, MAT096. 4 credits; 6 hours (3 lecture, 3 lab). Fulfills “Pathways: Flexible Core-Scientific World”
