This is a year-long course introducing the biological sciences. Beginning with the physical and chemical foundations of the natural sciences, we move on to discuss the basic unit of life, the cell. We examine the structure of cells, the fundamental processes that cycle energy through the biological world (photosynthesis and respiration), and cell reproduction. This leads to a discussion of the importance of DNA in genetics and evolution, and now, in genetic engineering. Finally, we examine the systems of the human body so that we can better understand ourselves as biological beings.
