Both Biology 11 and Biology 12 emphasize the Nature of Science themes: change, diversity, energy, equilibrium, matter, and systems. Biology 11 and Biology 12 refine students’ explanations of the nature of science and technology and the interaction between biology and technology. Students elaborate the impact of biology and associated technology on society and of the limitations of the biological sciences, science in general, and technology in solving societal problems. Laboratory work is integral to all science programs.

Unit 1: Maintaining Dynamic Equilibrium II

All living organisms struggle to maintain an internal balance in response to the constant pressure of external phenomena. This unit investigates the role of chemical and electrochemical systems in the regulation of homeostasis. The impact of disease, medical technology, and drugs will also be explored.

Unit 2: Reproduction and Development 

Reproduction is essential for the continuity of a species. This unit investigates the reproductive process at the cellular and multicellular levels. The influence of reproductive technologies will also be explored.

Unit 3: Genetic Continuity

Much of the structure and function of organisms is determined by their genetic material. This unit investigates the structure and replication of DNA, its transcription to RNA, and its translation into proteins. Discussion of how genes flow from one generation to the next serves as an introduction to basic genetics. The effects of mutation, genetic disease, and genetic engineering will also be explored.

Unit 4: Evolution, Change, and Diversity

This unit investigates evidence and mechanisms of evolution and offers an exploration of the implications of evolutionary mechanisms for concepts such as antibiotic resistance and diversity of life. Students explore the role of the environment on biodiversity change and speciation.
