The communication option was a joke, it was soo pathetically easy I wrote 24 pages (8 pages alone for the vision and auditory 8 marker). I learn't so many complex procedures and complexes to do with nerves, action potentials and receptors in other animals.
I liked part B as it really did involve applying your knowledge, it seems thats what their really testing in the HSC. Trying to separate out the ones that just 'wrote learn' from the ones that can actually apply the knowledge.
The ethical issues for transgens for god sent. As I was able to bring in my case study of genetic engineering to increase L-Tryptophan in sleeping pills which also increased the toxic amino acid EBT which killed 31 people in the 1980's.
for the 8 marker I discussed everything I could think of. In a nutshell I stated their identification process was valid in that they studied the ulcers under microscope on slides in a controlled enviroment and also in inidivudals where it was possible to monitor the growth, size and appearance of the ulcers which may indicate bacterial infection. I to brought in Koch's postulates, stating that even though Marshal exhibited the symptons, the bacteria should still have been once again isolated and shown to be the same as the one he swallowed. And that this procedure should have been repeated on a larger scale to increase reliability of the results.
For the experiment we had to design I basically did a replication of the year 11 prac in which you place three young species of the plants in test tubes with water and cotton buds on the top to prevent water loss from evaporation. Then mark on the test tubes the initial water level for each plant, place one in hot dry conditions with no shade, another in cooler conditions with shade and a control indoors. Mark the water level on the test tubes every 12 hours over a 3 day period and compare the results at the end.
I felt I was a bit hazy on the problems with metabolic wastes as for this dot point I more concentrated on the effects of carbon dioxide, where as this was asking for problems with nitrogenous wastes. I still included a snipet about CO2 at the end just in case it was relevant.
I'm also interested to hear what other people wrote for the epidemiology data for lactose intolerance. BTW is lactose intolerance a genetic non infectious disease or a nutritional non infectious disease. I kind of had to take a stab with that.
All in all, if I don't get band 6 their must be some bloody smart kids out there (points finger in JR, PLC & SBH's direction).
