The OCR GCSE Biology Paper 3 (June 2022) addresses key biological processes such as protein synthesis, transpiration, and photosynthesis. Topics include genetic inheritance, elephant thermoregulation, and human health conditions like dementia and liver disease. The paper emphasizes practical investigations, including stomatal density and microscopic observations, alongside environmental issues like plastic pollution and genetic engineering of organisms. Ethical considerations, experimental design, and real-world applications in conservation, agriculture, and disease management are central to the assessment.
