it says in my notes that :dolbinau said:For Malaria. , I have easy things to remember (stolen from this thread)
19th century - Sir Patrick Manson discovered mosquitoes can carry worms and hypothesised mosquitoes might be the vector for malaria
19th century - Ronald Ross discovered Anopheles Mosquito was the transmission of malaria
Early 20th century - synthetic quinine used to treat
WWII - Chloroquine used to treat
Mid 20th century - WHO used DDT to destroy swamps
General dates, little names. Hopefully it's enough
yes you're correct, Grassi named the female Anopheles mosquito as the vector. Ross discovered plasmodium as the cause of malaria by dissecting stomach of mosquito and explained the complete lifecycle of plasmodium.gloworm14 said:it says in my notes that :
1897- Ross discovered 'plasmodium' was the cause of malaria
1898- Grassi was the one that discovered that malaria was transmitted by the Anopheles mosquito
can someone verify?

are we expected to know every development?hoochiscrazy said:Heres some notes on the historical developments
–4 BC: Greeks thought that the symptoms of malaria were caused by either breathing in marsh vapours or bites of insects that live in marshes
–1880: Laveran observed micro-organisms in fresh blood from malarial patients and suggested that malaria was caused by this micro-organisms
–1886: Golgi observed asexual reproduction of microbe in blood of patients
–1894: Patrick Manson proposed that malaria is transmitted by mosquitoes
–1898: Grassi discovered that malaria was transmitted by the Anopheles mosquito.
–1897-1899: Ronald Ross established that the protozoan Plasmodium was the cause of malaria, winning the Nobel Prize.
–Early 20th: Treatments of malaria were developed, including anti-malarial drugs such as quinine. Efforts to stop the spread of malaria include using DDT to kill the disease vector – the mosquito.
–Today: Resistance to quinine and other drugs by the Plasmodium, as well as DDT resistance by the mosquitoes has become a problem. Development of a malarial vaccine is the main direction research is going.
probably most of it if its and 8 mark question. guess it depends of the question. But its in the syllabus so they could ask it.gcmk said:are we expected to know every development?
Law of segregation=law of independant assortment? not sure :/pooja_107 said:I AM SOOOOO CONFUSED.....does any1 know what the hell the law of segregation and the law of independant assortment is???? IN SIMPLE TERMS??? and how does law of segregation lead to variability???????????????????

~define the term ‘threshold’ and explain why not all stimuli generate an action potential...
I have no idea why I've never even heard of this....I dont see it any where in my notes or text book and googling sure didn't help much either lol. Can anyone help me out here? thanks...
oh btw are we supposed to learn innate and learned behaviours of animals?
gez 5 marks.Takuto said:Q: Old age is not a disease. Discuss the difficulties in defining the terms health and disease.
5 marker from past HSC
dont think anyone has covered this yet =]
Takuto said:I'd choose a prac thats not been mentioned yet and do a test run
they havent asked it before, so i dunnohoochiscrazy said:Yeah so the questions just basically know method some general safety precautions and variables and control/ equipment ect ect hmm if i would have to hav a guess model natural selection, kidney disection or enzymes one although that one would be a massive question so it may just ask for temp or pH or substrate []
