View topicsAdvanced Higher Biology covers Cells and Proteins, Organisms and Evolution, and Investigative Biology, assessed by an SQA exam and a substantial independent project-based research report.
The content is university-preparatory: protein structure and function, membrane proteins, communication and signalling, laboratory techniques including chromatography and electrophoresis, field techniques, evolutionary biology, sexual selection and parasitism.
The project is the largest single component and the one students most often underestimate. Planning a genuinely testable investigation, gathering enough data, and applying statistical analysis correctly are the things worth getting expert help with early.
Important Topics
- Cells & ProteinsProtein structure, membrane proteins, communication, signalling and the cytoskeleton.
- Laboratory TechniquesChromatography, electrophoresis, immunoassay, centrifugation and cell culture.
- Organisms & EvolutionEvolutionary history, variation, sexual selection, parasitism and co-evolution.
- Field TechniquesSampling, monitoring populations and ethical and safe field practice.
- Investigative BiologyExperimental design, controls, pilot studies, reliability and validity.
- Statistics & Data AnalysisDescriptive statistics, error bars, significance testing and interpreting results.
- Project ReportThe extended independent investigation and its formal scientific write-up.
