Disease that cannot be caught: homeostasis failing, the genetic and environmental causes, and how epidemiology separates correlation from cause.
These are the statements the Biology syllabus makes about Module 8: Non-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.
Negative feedback holds a variable near a set point; positive feedback drives a process to completion and is rare outside specific events. Naming the receptor, control centre and effector makes the mechanism explicit.
Genetic, environmental and multifactorial causes, including the diseases that are neither purely inherited nor purely acquired. Most real disease sits in the multifactorial middle.
How a dysfunction propagates through a system, and why the observable symptom is often far from the initial failure.
From prevention through screening to treatment, and the trade-offs between them. Screening programmes are judged on sensitivity, specificity and what happens to those tested.
Cohort, case-control and cross-sectional designs answer different questions. Correlation is not causation, and confounding variables are the reason an association can mislead.
Incidence counts new cases over time; prevalence counts all existing cases at a moment. A disease can have falling incidence but rising prevalence, and that combination usually means treatment is improving.
Measuring a physiological variable under controlled conditions and evaluating whether the observed regulation is feedback or simply the body's baseline drift.
Analysing a data set for association, identifying plausible confounders, and judging what the data can and cannot support.
HSC Biology - Trial Paper Shape is 100 marks in 180 minutes. Questions on Module 8: Non-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 8: Non-infectious Disease is module 4 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.
