How pathogens cause disease, how the body defends itself, and how populations rather than individuals respond to outbreaks.
These are the statements the Biology syllabus makes about Module 7: Infectious Disease. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Pathogens — bacteria, viruses, fungi, protozoa and prions — differ in structure, replication and treatment. Antibiotics act on bacteria only, which is why viral illness cannot be treated with them.
Direct contact, droplets, vectors, contaminated food and water. Knowing a pathogen's route is what makes a control measure sensible rather than generic.
First line barriers, the innate response with inflammation and phagocytes, and the adaptive response with B and T cells. The adaptive response is specific and produces memory.
Active immunity makes your own antibodies and lasts; passive immunity is borrowed and fades. Herd immunity protects those who cannot be vaccinated, which is why coverage thresholds matter.
Incidence, prevalence, morbidity and mortality describe different things. Choosing the right measure for a question is most of the work.
Quarantine, hygiene, vector control, antimicrobials and vaccines, evaluated for effectiveness and for the selection pressure each creates.
Investigating factors affecting microbial growth, and evaluating whether a zone of inhibition reflects effectiveness or merely diffusion rate.
Resistance arises from pre-existing variation that is selected by antibiotic use. It is natural selection observed in real time, which is why the language matters.
HSC Biology - Trial Paper Shape is 100 marks in 180 minutes. Questions on Module 7: Infectious Disease are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Biology uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Module 7: Infectious Disease is module 3 of 4 in Biology. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Biology dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
