Abstract: The November 2020 GCSE Combined Science Biology Paper 1 (Foundation Tier) explores key biological concepts, including the impact of lifestyle on health, aerobic and anaerobic respiration, and exercise-induced physiological changes. It evaluates experimental methods, such as the effect of sugar solutions on osmosis in potatoes and the influence of environmental factors on transpiration in leaves. Topics in human biology include the immune response, pathogen prevention, HIV transmission, and antibiotic resistance. The paper also addresses drug testing, the digestive system, enzymatic processes, and villi adaptations for nutrient absorption. Keywords: biology, respiration, osmosis, pathogens, immune system, drug testing, enzymes, transpiration.
