GCSE Biology: Infection & Response — Deep Revision Workbook

GCSE Biology: Infection & Response — Deep Revision Workbook is the extended-practice set for AQA GCSE Biology Topic 3 (Infection and Response, 4.3), mapped to the DfE National Curriculum. Learners work through communicable disease and the four pathogen types with named examples (measles, HIV, TMV, salmonella, gonorrhoea, malaria, rose black spot), how disease spreads and how to reduce spread, the body’s non-specific defences (skin, mucus, cilia, stomach acid), the immune system (phagocytosis, antibodies, antitoxins), vaccination and herd immunity, monoclonal antibodies and their uses, antibiotics versus painkillers, antibiotic resistance and natural selection, drug discovery and preclinical and clinical trials including placebos and double-blind testing, and plant diseases and defences. Sections 1–4 hold more than thirty auto-marked questions that build from foundation to higher tier; Section 5 is an extended exam-style 6-mark application with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
