Biology Q&A by dot point
A short Q&A bank for every TAS Biology syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Unit 1: Biodiversity and the Interconnectedness of Life
Explain cell theory and compare prokaryotic and eukaryotic cells.
Describe the system of biological classification and explain how organisms are named and grouped.
Describe the carbon, nitrogen, and water cycles and the role of organisms in moving matter.
Identify the biotic and abiotic components of ecosystems and explain how abiotic factors shape distribution.
Explain how energy flows through food chains and webs and why energy is lost at each trophic level.
Define the levels of biodiversity and describe how species richness and evenness are measured.
Explain the factors that change population size and describe methods used to estimate populations.
Describe the types of interspecific relationships and explain their effects on the organisms involved.
Unit 2: Cells and Multicellular Organisms
Describe the structure of the cell membrane and explain the mechanisms of membrane transport.
Identify the main organelles of eukaryotic cells and relate their structure to function.
Explain how enzymes work as biological catalysts and how their activity is affected by conditions.
Explain how the surface area to volume ratio limits cell size and exchange.
Unit 3: Heredity and Continuity of Life
Explain the principles and applications of key biotechnology tools and evaluate their implications.
Compare mitosis and meiosis and explain how meiosis generates genetic variation.
Describe the structure of DNA and explain how transcription and translation produce proteins.
Apply Mendelian inheritance to predict genotype and phenotype ratios and explain sources of variation.
Unit 4: Change Over Time
Describe and evaluate the lines of evidence that support evolution.
Explain how natural selection acts on variation to produce adaptation over generations.
Use the Hardy-Weinberg principle and describe the factors that change allele frequencies.
Explain how reproductive isolation leads to speciation, including allopatric and sympatric modes.
