Biology, Grade 12
University Preparation SBIU
This course provides students with the opportunity for in-depth study of the concepts and processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biochemistry, metabolic processes, molecular genetics, homeostasis, and population dynamics. Emphasis will be placed on the achievement of detailed knowledge and the refinement of skills needed for further study in various branches of the life sciences and related fields.
Prerequisite: Biology, Grade 11, University Preparation Big Ideas
Biochemistry
• Technological applications that affect biological processes and cellular functions are used in the food, pharmaceutical, and medical industries.
• Biological molecules and their chemical properties affect cellular processes and biochemical reactions.
• Biochemical compounds play important structural and functional roles in cells of all living organisms.
Metabolic Processes
• All metabolic processes involve chemical changes and energy conversions.
• An understanding of metabolic processes enables people to make informed choices
with respect to a range of personal, societal, and environmental issues.
Molecular Genetics
• DNA contains all the genetic information for any living organism.
• Proteins control a wide variety of cellular processes.
• Genetic research and biotechnology have social, legal, and ethical implications.
Homeostasis
• Organisms have strict limits on the internal conditions that they can tolerate. • Systems that maintain homeostasis rely on feedback mechanisms.
• Environmental factors can affect homeostasis.
Population Dynamics
• Population growth follows predictable patterns.
• The increased consumption of resources and production of waste associated with
population growth result in specific stresses that affect Earth’s sustainability.
• Technological developments can contribute to or help offset the ecological footprint
associated with population growth and the consumption of natural resources.
