Infection and Response: o How pathogens (bacteria, viruses, fungi) cause diseases, and how the immune system defends the body against infections. o The role of white blood cells, antibodies, and antigens in immune responses. o Vaccination and how it helps protect against diseases by stimulating immunity. o The problem of antibiotic resistance and how bacteria evolve to become resistant to treatments. 4. Bioenergetics: o Photosynthesis: the process by which plants make their own food, including the factors that affect the rate of photosynthesis (e.g., light intensity, temperature, carbon dioxide concentration). o Respiration: the process by which cells release energy from glucose, and the difference between aerobic (with oxygen) and anaerobic (without oxygen) respiration. 5. Homeostasis and Response: o The concept of homeostasis and how the body maintains stable internal conditions, such as temperature and blood glucose levels. o The role of the nervous system in detecting and responding to stimuli. o Hormonal control, including the regulation of blood glucose by insulin and the body's response to stress through adrenaline. o An understanding of the menstrual cycle and how hormones control different phases. 6. Ecology: o Ecosystems and how organisms interact with each other and their environment, including food chains, food webs, and energy transfer through trophic levels. o The carbon and nitrogen cycles and how these elements are recycled through ecosystems. o The impact of human activities on ecosystems, including pollution, deforestation, and climate change. o Conservation strategies to protect biodiversity and sustain ecosystems. 7. Plant Biology: o The process of photosynthesis in plants, the role of chlorophyll, and factors affecting its rate. o How water, nutrients, and sugars are transported in plants through the xylem and phloem. o Transpiration and its role in moving water within plants. 8. The Use of Biological Resources: o Biotechnology and genetic engineering, including the use of genetically modified organisms (GMOs) to improve crop yields and resistance to pests. o Selective breeding to develop desirable traits in animals and plants. the impact of these technologies. o Sustainable farming methods to increase food production while reducing environmental harm. 9. Health and Disease: o Non-communicable diseases (e.g., heart disease, cancer, diabetes) and the lifestyle factors that influence their development (e.g., diet, exercise, smoking). o Public health initiatives to reduce disease spread and improve health outcomes. o The importance of maintaining a healthy lifestyle to prevent diseases and promote well-being. This paper will consist of multiple-choice questions, short-answer questions, and longer-answer questions that test students’ ability to apply their knowledge of biological and environmental sciences. Students will need to demonstrate understanding of scientific concepts and their relevance to real-life situations, while also analyzing data and interpreting biological processes in different contexts. 2 0 1 Figure 1 shows a food chain.
