HOW DID WE ALL GO?

[Zahta]

Same im like oxygen but that isn't  a  compound.  Then i wrote nadph then i changed it back to oxygen.  Argh. 

[InsaneMcFries]

I'm fairly certain VCAA has referred to oxygen and other things as compound "variable" before though...

Same here. 

[pie1234]

i did oxygen too.. was it nadph?

[lukeim]

won't it be oxygen cause i was thinking of oxygen gas, thus its a compound

[Gazillionaire]

won't it be oxygen cause i was thinking of oxygen gas, thus its a compound

That exactly what i thought

[ligands]

oxygen gas o2 is a molecule not a compound

[duhherro]

Was it just me or did anyone else get the DNA multiple choice question wrong? The right answer was 75 ot 25

Yeah i got 75. LOL

[Markkiieee]

What do you guys think you got \75?

Dunno if you guys had trouble with this, but from Douchy:

If you are upset about Q8 aii. Take heart. I think the question is defective. It asks you to Name compound Y. Since [ M ] is clearly the Light-dependant stage of Photosynthesis, and [ P ] is Cellular respiration (as the table below this diagram makes clear), that means Compound Y is a product of the light dependant stage, that is used by cellular respiration. Im sure the answer they wanted was Oxygen, but Oxygen is NOT a compound. It can't be glucose because although that IS a compound, it's not a product of the light dependant stage, but of the light independent stage, and is shown appropriately in the diagram coming out of [ N ]. It can't really be NADPH either - although that is a compound, because Y is shown to be used by [ P ] which NADPH is not. So there really is no correct answer.

I don't know this for sure but I suspect that the VCAA will just not count that question - or will accept any of the above unsatisfactory answers. I'll certainly be writing to the VCAA to suggest that.

So don't be upset. You should only ever kick yourself for things you could have done right but didn't. In this case, I think it was an unanswerable question.

wow thank god!

[Zahta]

What did you guys write for the 50% carbon dioxide  question

[ligands]

i said to re-use the co2 produced from process P and to remove the pyruvate from the system so no co2 would be produced from process p, not sure if there right tho

[duquesne9995]

What was the q asking again?

[InsaneMcFries]

I said that (most likely wrongly) that process P will be controlled to allow CO2 produced in the power plants to be used by cellular respiration instead. But a lot of people said that the rate of photosynthesis would be higher than the rate of cellular respiration, so it uses more, but that was my cohort.

The question was quite complex, it was about Chlorella bacteria or something.

wow thank god!

I'm with Douchy on this - oxygen is NOT a compound, it's an element. Reminds me of the time last year when VCAA marked 'ethene' wrong because they thought it wasn't an organic compound.
