They study the human immune system and the interactions between its components to provide immunity to a specific pathogen. Students consider how the application of biological knowledge can be used to respond to bioethical issues and challenges related to disease. Students consider how evolutionary biology is based on the accumulation of evidence over time. They investigate the impact of various change events on a population’s gene pool and the biological consequences of changes in allele frequencies. Students examine the evidence for relatedness between species and change in life forms over time using evidence from paleontology, structural morphology, molecular homology and comparative genomics. Students examine the evidence for structural trends in the human fossil record, recognising that interpretations can be contested, refined or replaced when challenged by new evidence. A student practical investigation related to cellular processes is undertaken in Unit 3 and is assessed in Unit 4, Outcome 3. The findings of the investigation are presented in a scientific poster format. |  |\n| --- | --- |\n| Area of Study 1\u003Cbr>In this area of study students focus on the immune response of organisms to specific pathogens. Students examine unique molecules called antigens and how they illicit an immune response, the nature of immunity and the role of vaccinations in providing immunity. They explain how technological advances assist in managing immune system disorders and how immunotherapies can be applied to the treatment of other diseases. Students consider that in a globally connected world there are biological challenges that can be mediated by identification of pathogens, the prevention of spread and the development of treatments for diseases.\u003Cbr>Outcome:\u003Cbr>On completion of this unit the student should be able to analyse the immune response to specific antigens, compare the different ways that immunity maybe acquired and evaluate challenges and strategies in the treatment of disease.\u003Cbr>Learning Dispositions:\u003Cbr>Resilience, Reflectiveness and Persistence – Moves on from adversity, mistakes and failures\u003Cbr>Collaboration and Ethical Behaviour-Gives and receives meaningful feedback\u003Cbr>Area of Study 2\u003Cbr>In this area of study students focus on changes to genetic material over time and the evidence for biological evolution. They consider how the field of evolutionary biology is based upon the accumulation of evidence over time and develop an understanding of how interpretations of evidence can change in the light of new evidence as a result of technological advances, particularly in molecular biology. Students consider the biological consequences of changes in allele frequencies and how isolation and divergence are required elements for speciation. They consider the evidence for determining the relatedness between species and examine the evidence for major trends in hominin evolution, including the migration of modern human populations around the world.\u003Cbr>Outcome: | Home Learning\u003Cbr>To consolidate classwork, students should:\u003Cbr>• Revise and summarise PowerPoint notes\u003Cbr>• Create mind maps for each area of study or study design dot point\u003Cbr>• Reflect on, practice and revise key skills and knowledge in preparation for future learning\u003Cbr>• Regularly update, and review, the Unit 4 Biology glossary\u003Cbr>• Find and fix errors made on Outcome Tasks and SACs\u003Cbr>• Read through, and annotate, experiment outlines prior to conducting an experiment\u003Cbr>• Watch Edrolo videos and complete set tasks\u003Cbr>• Complete provided SAC and exam preparation tasks\u003Cbr>• Read widely and watch documentaries on content related to each Area of Study to deepen understanding and make connections\u003Cbr>Parent/Guardian can support their student by:\u003Cbr>Encouraging discussion of the application of ideas/concepts that ","cbCaiiYFMWKguPzO","https://ap.wps.com/l/cbCaiiYFMWKguPzO","pdf",276779,"English","# Overview\n## Area of Study 1: Immune response\n## Area of Study 2: Genetic change and evolution\n## Area of Study 3: Student-designed scientific investigation\n## Home Learning and Resources","[{\"question\":\"What topics are covered in Year 12 Biology Unit 4 overview?\",\"answer\":\"The unit covers immune system responses, applications of biological knowledge to disease-related bioethical issues, evolutionary biology evidence over time, and how population gene pools and allele frequencies change.
