HSC Biology | Study Notes Public health campaigns are an important part of NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 focuses on how non-infectious diseases can be prevented at the population level, and HSC materials directly use campaigns about smoking, skin cancer and cervical cancer as examples of disease prevention in Australia. These examples also show how epidemiological data can be used to judge whether a c

HSC Biology | Study Notes Epidemiological studies are a key part of NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 specifically asks students to analyse patterns of non-infectious disease in populations, evaluate the method used in an example of an epidemiological study, and evaluate the benefits of engaging in an epidemiological study. The course also links this work to analysing incidence, prevalence and mortality d

HSC Biology | Study Notes Incidence, prevalence and mortality are key ideas in NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 specifically requires students to collect, represent and analyse data on the incidence, prevalence and mortality rates of non-infectious diseases, and to analyse disease patterns in populations using epidemiological studies. HSC materials also regularly test how these measures are calculated an

HSC Biology | Study Notes Causes of non-infectious disease are a key part of NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 specifically requires students to investigate the causes and effects of non-infectious diseases in humans, including genetic diseases, diseases caused by environmental exposure, nutritional diseases, and cancer. HSC marking guidance also makes clear that non-infectious diseases are not caused by

HSC Biology | Study Notes Thermoregulation in animals is a key part of NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 specifically includes investigating the mechanisms organisms use to maintain their internal environment within tolerance limits, including behavioural, structural and physiological adaptations in endotherms that assist in maintaining homeostasis. HSC materials also compare ectotherms and endotherms usi

HSC Biology | Study Notes Negative feedback is a key part of NSW Biology Stage 6, Module 8, Non-infectious Disease and Disorders . This topic matters because Module 8 specifically requires students to construct and interpret negative feedback loops that show homeostasis, using examples such as temperature and glucose. Negative feedback helps organisms maintain their internal environment within tolerance limits, even when external conditions change.   In this lesson what a sti

HSC Biology | Study Notes Animal responses to pathogens are a key part of NSW Biology Stage 6, Module 7, Infectious Disease . This topic matters because Module 7 specifically requires students to analyse responses to pathogens by assessing the physical and chemical changes that occur in host animal cells and tissues. The module sample also explicitly includes symptoms such as coughing, sneezing, snot, fever and inflammation, and asks students to explain how these responses he
