guys what is the final answer for question 4 i put D?
It can't be D. I therefore put C - why it can't be D is that it doesn't state anywhere in the scenario that the Wollemi Pine still exists and does actually come from outside the country therefore "Preventing the importation of Wollemi Pines into Australia' can't be correct. They stated "The last small population of Wollemi Pines grows in a remote part of a national park in Australia"
I also believe Wollemi Pine is native to Australia?
But they specifically pointed out the fact Phythophthera lives in the soil therefore washing soil from scientist's shoes will prevent further spread of the fungus to other monocots and thus these pines. (Which i've read somewhere in a text book to do with Phythopthera - If I can find the source i'll put it up.)
It was a trick question anyway, since the first thing you usually suspect when you 'prevent the spread' of something is to stop it from coming into the country, quarantine, protecting our wildlife and agriculture etc. Personally I think even if there were Wollemi Pine being imported in, it wouldn't exactly help these scientists who are looking for "strategies to prevent these pines becoming infected"
For question 1:
I did put C, but now looking at the question in the booklet closer again, it's more likely it's going to be D:
My argument? The fact the diagram states they want a "Lock and Key" Method. In the various textbooks i've looked at, the lock and key method shows that answer C) to that question is the product, whereas A B or answer D) is the substrate. These are actually "theories of enzyme action"
I still believe i'm right with the answer C in some cases to do with the lock and key method, BUT in this SPECIFIC diagram, it shows the substrate being 'locked' and the product being created, I believe the answer is D. And, I don't think anyone who has argued is correct or incorrect about C also being a substrate, but not according to this diagram, and the fact they want you to use the theory to determine it.
