BIOL 1155 - Principles of Biology II



5 Credits
Introduces important biological principles and is intended for biology and biology-related majors. It is the second of a 2-semester course series and, also serves as a prerequisite for several other subsequent biology courses that are part of the Biology Minnesota State Transfer Pathway (AS-P). There is an emphasis on organism to ecosystem levels of biology surrounding the core theme of evolution. Topics include the origin of life, population evolution, phylogenetic classification, ecology, and biodiversity. Labs emphasize the process of scientific inquiry where students study organisms, their comparative anatomy, and their interrelationship with the environment through research projects. Lab exercises involve individual and group work in campus lab facilities and field studies off-campus. Students will gain hands-on experience in the safe handling and use of living and preserved organisms as well as laboratory instruments and equipment.
