BIS 2A concentrates on the cellular basis of life, concentrating on the structures and functions of cells and the biological molecules from which they are formed, the ways by which cells acquire, transform, and use chemical energy, and the mechanisms by which genetic information is stored, safeguarded, transmitted from one generation to the next, and used in reproduction and development, with the immune systems serving as a example of complex eukaryotic development.
