BIOLOGY 20 COURSE OUTLINE
Biology 20 consists of four units of study:
A. Energy and Matter Exchange in the Biosphere
B. Ecosystems and Population Change
C. Photosynthesis and Cellular Respiration
D. Human Systems
UNIT A : Key Concepts
 Biosphere
 Equilibrium
 Trophic levels
 Food chains, food webs and ecological pyramids
 Carbon, nitrogen, oxygen and phosphorous cycles
 Water properties
UNIT B: Key Concepts
 Ecosystem
 Niche
 Biotic/abiotic characteristics
 Limiting factors
 Binomial nomenclature
 Adaptation and variation
 Population
 Natural selection
 Species
 Evidence for evolution
UNIT C: Key Concepts
 Absorption of light by pigments
 Light dependant and independent reactions
 Glycolysis
 Krebs cycle
 Electron transport systems
 Aerobic and anaerobic respiration
 Muscle contraction
UNIT D Key Concepts
 Structure and function of major systems: digestive, respiratory, circulatory
excretory
 Chemical nature of carbohydrates, lipids and proteins
 Chemical and physical digestion
 Digestive enzymes
 Gas exchange
 Blood composition
 Immune response
 Renal function
The Biology 20 course consists of a variety of assessments: quizzes, unit exams, lab work
and lab skills.
It is expected that all students complete all assessments in the course.
