This maybe a stupid question but in question 2 of the shorts was the A = b+c+d , build up anabolic or break down catabolic? Think there was a trick to that question.

I said catabolic but I am not really sure. I felt the short questions were phrased badly over all.

Thanks i said the opposite because it was not exactly clear. Yeah, whoever wrote out the paper must have thought it was an English exam or something.

It was very clear that if A becomes B + C + D that A had been broken down, therefore the answer is catabolic

Predictability is one of the only things that takes the edge off the whole "learn 2 school years' worth of material for a single exam to determine your grade" thing.

I'm all for getting us to think, but it's such a high stakes exam that it hardly seems like the place for it. Just let us demonstrate what we've spent the last 2 years in class learning rather than trying to catch us out in order to, what, teach teachers a lesson about teaching to the test, and send a warning to future LC students?

I agree with the high stakes comment, however, a predictable exam does no one any favours.

That exam will reward a students' ability to link topics together as well as good teaching that doesn't simply follow a rote approach

Oh I drew out both the carbon and nitrogen cycles and from there just bullet pointed out plant and animal roles in each like death and decay, nitrates, all that jazz

Anyone got the answers up online??

Damn, I thought because A had turned into three things it had grown, therefore anabolic?

Same here, are the answers up anywhere yet?

I will tell you why you are wrong .

If it was anabolic they would have to say plus energy on the left hand side .

Therefore it is catabolic . As one of a b or c could be energy and other two are products .

Hope this clears things up for people who said anabolic .

Inspector Coptoor

Well said.
And the reaction underneath that question, the breakdown of the fat is also catabolic.

''rabbit census''. It should give the corrector a laugh more than anything..

Capture/recapture method... there's a formula with it, anyone else say that.?

What was the bit about the horse meat and pig meant and how you distinguish between them? 😞

Omg yes I just guessed that!! Thank you

I said that the result would be the same, as in the two DNA samples still wouldn't match, but I'm not sure if I understood the question..

I said the results would be different as horse DNA and pig DNA would produce a different pattern of fragment distribution in the profile as their DNA isn't the same .

Kind of interesting how you said that. The question asked would the result be the same, and that could go either way.

You could say yes, it would be the same as it would show that the meat is contaminated in both cases. Or like you, you could say it wouldn't be the same, as the specific DNA profiles would be different. Seems like poor wording on the question overall as it could be read as asking either.

Was it genetic screening or genetic profiling used?

I agree . Poorly worded question . I was uncertain which answer to give . Both seem right .

The Other Padfoot

For question 4 about the structural features present in one kingdom and not in the other, did you have to give actual structures or could you mention that for example Fungi contains chitin while Animalia does not? I kinda messed up q2 so I'm down to five short questions

Badwulf

Does anyone have the answers?

For the test for alcohol I said acidified sodium dichromate instead of acidified potassium dichromate. I'm sure it's still correct because we use it in chemistry but I wonder would they give marks for that?

Photosynthesis, Respiration, Enzymes, Ecology, Genetics, Human Immunity, Bacteria and the IAA experiment would be a good start

Ye can send the thank you cheques in the post for these spot on predictions whenever ye get a chance lads. Thanks

They should.
Same idea.
Did you go into the colour change observed?

i just drew out the the diagrams with the process involved in between the arrows would that be enough to get thefull marks?

jimbob95

does it matter if I left out the water bath in the diagram for preparing alcohol? is function of the cerebrum excretion? for Q14.c.i did you have to elaborate much i mean i just said by osmosis!

Flickka

Was it an anabolic or catabolic reaction in the short questions?
