The exam assesses foundational biological knowledge on topics such as pathogen transmission, immune responses, photosynthesis, cell division, genetic material, plant adaptations, and diffusion. Key concepts include HIV prevention, mitosis, carbon dioxide’s role in photosynthesis, plant water transport, and surface area-to-volume ratio in organisms. Practical applications involve data analysis, experimental design, and risk assessment in microscopy. The exam emphasizes interpreting data, explaining biological processes, and evaluating scientific principles. Keywords: GCSE Biology, Foundation Tier, pathogen transmission, immune response, photosynthesis, mitosis, genetic material, diffusion, plant adaptations.
