What does Edexcel Combined Science Paper 2: Biology 2 cover?

Similar to paper 1, the exam covers the foundational knowledge of cells, enzymes and basic material transportation methods such as diffusion and osmosis. This ensures that students have an appropriate background before moving on to later biology topics. Microscopy for example is required to understand how we have determined details about how plant structures work and function. How does photosynthesis happen? This is a question we could not answer without the tools of microscopy and also the basics of chemistry. The overlap between disciplines is self-evident when you consider the background you need to know before understanding concepts like photosynthesis and respiration. 

The paper in CB6 tests students’ knowledge of the principles which underpin food chains, namely photosynthesis and the transportation processes which facilitate it. In CB7 – Animal coordination, control and homeostasis; hormones and metabolic processes, alongside the menstrual cycle are addressed. Additionally, control of blood glucose and diabetes are introduced. CB8 includes transport and exchange systems in animals and plants which involves an understanding of the circulatory system, how the heart works and cellular respiration. Finally, in CB9, ecosystems are covered and related topics of ecology. These include biotic and abiotic factors, parasitism, mutualism and biodiversity. Material cycles are the last topics to appear in CB9.
