there's def skill involved in practical components - ie applying your knowledge and concepts of validity, reliability in procedural methods etc etc to questions. i reckon thats were quite a few people screw up.

well u would tie in your knowledge of vaccinations and how they work in preventing and controlling spread of disease. It is likely that the 8-marker will have some sort of stimulus. And if its about cervical cancer, it will mention that human papilloma virus (HPV) causes cervical cancer...

hope im going in the right direction with this answer. A stimulus is necessary for a response to be generated by the Central Nervous System, which is carried out by effectors instructed by the Peripheral Nervous System. For example, if one touches a very hot surface (such as a stove...

lol I'll have a shot from the top of my head. Louis Pasteur carried out an experiment, in which he disproved the spontaneous generation theory. He placed a beef broth in two swan neck flasks, boiled the beef broth thoroughly to kill any microorganisms. Pasteur then broke the swan neck on ONE...

My teacher said she's seen people getting 94/100 raw, which apparently scales to pretty much 100.

Question: Define the term threshold and explain why not all stimuli generate an action potential. Accumulation - Grey Mangroves in NSW store excess salts in their leaves, which they then discard (fall off), hence assisting in internal salt regulation. Secretion - River Mangroves in NSW have...

omgg yesssss so true if u look at all other transerve diagrams, xylem is bigger than phloem.

Well I think that it is just that one thick layer of elastic muscle fibres. The only layers I know of in arteries are: Connective tissue (outer layer) Smooth, elastic muscle fibres Endothelium Then comes the lumen (hole inside). Yeah so am I.. but meh let's not confuse ourselves and stick...

maybe it was this one? basically here i think all we had to realise was that the xylem was in the centre (notice the smaller vessels).. and thats where passive transport occurs. phloem, larger vessels, were on outside, where active transport occurs. Edit: well well.. i'm wrong again. The...

YESSS! I got that wrong.. stupid me. The thing to that question was that realising the vessel with the squiggly, spirally things in the middle was the xylem (the advice line guy said that they are the tracheids - and thats how u distinguish from phloem). Hence passive transport occurs in...

Question: Identify the current technologies that allow measurement of oxygen saturation and carbon dioxide concentration in blood and describe and explain the condition under which these technologies are used.

who here does the communication option?

yeah, that's even easier. just like this: Just remember, xylem is always on the inside, and is made up of a vascular bundle of heaps of narrow xylem vessels. The phloem is on the outer part, towards the mesophyll cells where photosynthetic products are produced. It just makes logical sence...

here's what i posted in another thread for this guy. lol i just did them in paint, very simplified. this is how our teacher taught them to us:

exactly that :) it addresses IDENTIFY, ASSESS and CONTROL.

do u mean 75%? and u talkin bout maths ext 1 or maths 2u? well to get like 94 in 2u u need around 105+ /120

lol havent u done risk assessments before wen doing pracs? Its basically where u identify risks, asses the risks in your practical, and then state how these risks can be controlled. I usually do it in a table, works best.

what they're saying is (i think) that candidates interpreted 'one condition' as one temperature, eg 45degrees, and thats it, disregarded other temp values. what the examiners were looking for was you using ONE of the variables, either pH or temperature. And to use it as an independent variable...

I love this dotpoint because its already addressed in my chemistry course. Drinking water supplies can be sanitised to a potable standard via Chlorination. Chlorination involves either bubbling Chlorine gas into the water supply, or dispersing a solution of Sodium Hypochlorite. Cl2(g)...

lol i enjoyed learning hsc chem... hence everything stayed in my head throughout the year. i didn't really forget anything... its all embedded up there. that's why im syked for the chem exam on nov 6th.
