Biology is a required course for all students. In biology, students will learn about the nature of cells and how cells function, evolve, and pass on their genetic traits. Students will also study the principles of genetics and the future of genetic technologies. Students will be introduced to concepts in basic ecology, plant and animal biology, embryology, micro-organisms and evolution theory as well.
