Grade+12+Biology+-+SBI4U

Welcome to //SBI4U//!! Throughout the course you will be learning the following:

[|Biochemistry] 1) Technological applications that affect biological processes and cellular functions are used in the food, pharmaceutical, and medical industries. 2) Biological molecules and their chemical properties affect cellular processes and biochemical reactions. 3) Biochemical compounds play important structural and functional roles in cells of all living organisms.

[|Metabolic Processes] 1) All metabolic processes involve chemical changes and energy conversions. 2) An understanding of metabolic processes enables people to make informed choices with respect to a range of personal, societal, and environmental issues.

[|Molecular Genetics] 1) DNA contains all the genetic information for any living organism. 2) Proteins control a wide variety of cellular processes. 3) Genetic research and biotechnology have social, legal, and ethical implications.

[|Homeostasis] 1) Organisms have strict limits on the internal conditions that they can tolerate. 2) Systems that maintain homeostasis rely on feedback mechanisms. 3) Environmental factors can affect homeostasis.

[|Population Dynamics] 1) Population growth follows predictable patterns. 2) The increased consumption of resources and production of waste associated with population growth result in specific stresses that affect Earth’s sustainability. 3) Technological developments can contribute to or help offset the ecological
