Unit 4: Maintaining the internal environment Biology
In order to survive, organisms must be able to maintain system structure and function in the face of changes in their external and internal environments. Changes in temperature and water availability, and the incidence and spread of infectious disease, …

Unit 2: Cells and multicellular organisms Biology
The cell is the basic unit of life. Although cell structure and function are very diverse, all cells possess some common features: all prokaryotic and eukaryotic cells need to exchange materials with their immediate external environment in order to maintain …

Unit 1: Biodiversity and the interconnectedness of life Biology
The current view of the biosphere as a dynamic system composed of Earth’s diverse, interrelated and interacting ecosystems developed from the work of eighteenth and nineteenth century naturalists, who collected, classified, measured and mapped the distribution …

Unit 3: Heredity and continuity of life Biology
Heredity is an important biological principle as it explains why offspring (cells or organisms) resemble their parent cell or organism. Organisms require cellular division and differentiation for growth, development, repair and sexual reproduction. In …
