Quick questions on Causes of infectious disease and pathogen types: HSC Biology Module 7
5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is structure?Show answer
Misfolded proteins. No nucleic acid, no cell structure.
What is mechanism?Show answer
A prion induces normal cellular proteins (often PrP in nervous tissue) to misfold into the same abnormal shape, creating aggregates that destroy brain tissue.
What are examples?Show answer
Influenza A (RNA virus, respiratory), HIV (retrovirus, immune cells), tobacco mosaic virus (plant pathogen affecting tomato and tobacco leaves).
What are generic disease names?Show answer
"A virus" or "a bacterium" scores no marks. Use full scientific names where possible.
What is bank a plant example?Show answer
Tobacco mosaic virus, wheat stem rust (Puccinia graminis) or crown gall (Agrobacterium tumefaciens) - the dot point explicitly requires plant pathogens, and many candidates lose marks by giving only human diseases.
