(iii) The only remaining natural ecosystems in Ireland, for example mountain land above the heather
line and salt marsh, are ones for which mankind has no use. true or false and explain why
I said about using high land for windfarms and that waterfalls could also be used for producing renewable energy (?) haha. Oh and I said that bogs were used for peat, and that people still used those sort of areas for recreation.

My impressions...
After I went over all the past exam papers yesterday, I was taken aback. Altogether 2 sections came up that have NEVER come up before: the kingdoms (classification or what its called) and the feckin Amoeba. I didnt bother studying them, but thank duck it came back to me later. Also, I wrote ribosomes instead of food vacuoles.
I thought those short questions was incredibly hard! 4 genetic crosses asked in the 'easy section'?? Well, that was grand for me, but still. And that swine flu thing was weird. I thought of putting down memory lymphocytes and stuff like that, but the thing is, that every flu is different, thats why we get it so many times in life, there are no general antibodies against flu???
And I heard it for the first time, that younger people were at more risk! So I wrote something like that old people were vaccinated, because they are weaker and if they had gotten swine flu, it might have killed them, but young people didnt bother with the vaccination, therefore they were more at risk of becoming ill. Do you think it would gain me some marks?
The whole paper was just totally weird. They asked questions that they have never asked before, DNA/RNA be my favourite topic and I was horrified. Wtf was that 'three outcomes' thing?!
My diagrams were unbelievably bad, by the way
Ecology question was really strange too, it was either very easy or very hard! That 'simple compound' was quite tricky too, I spent lifetime on figuring out what they meant, in the end I wrote "from NADPH which gets it from splitting of the H2O".
I think they went to huge details over the whole paper. And very weird phrasing and questions asked. I was often not sure what exactly they wanted me to write down, or how long my answers should be. Not many straightforward one word long answers
Also, what substances are transported by the hepatic portal vein?
Still hope to get an A1, but this paper was an unpleasant surprise for me.
Even the two experiments I hated the most came up! (the heart and IAA). My diagram of the heart looks like a ball with four weird ducts emerging from it. I wrote a note in the end to the examiner to apologize for my awful drawings 0 -

They did that in Business aswell.
I feel like they've almost changed the formart of the LC in general this year.
Thats very true. In english we didnt get the picture comprehension, therefore no picture short storied. And no Boland
Maths - curve, which was actually a line. I dont think they were this cunning ever before?
Well, and Biology, thats all I have done so far. And so far, so strange. :rolleyes:
Oh yeah, I just remembered, what did ye write down on those "cold-like diseases and antibiotics?" I noticed only in the last minute, that its probably viral, so the antibiotics would not work, I had put down something about the antibiotic resistance before. I thought that was kind of tricky too.0 -
Liked this exam was abit of a challenge... Some very detailed questions, happy that Amoeba came up Love them little yokes...
Dunno, I expected a paper like this. About time they shook things up a little bit I suppose, they were probably thinking that.0 -

As for the crosses... why didn't you use a punnet square? I did!
I did too,,,,,,
Over all I thought the paper was pretty nice......0 -

I did ordinary biology today. I officially took up the subject in January, I never took the mox, I had read over unit 1 + 2 a few times in a revision book and only started studying last week (due to pure lazyness)
I studied 5 chapters,
food, ecology, photosynthesis, respiration and genetics.
They all came up and I answered 5/6 only section 1, none of the experiments and 4/6 in the long questions.
It was the luckiest test I've ever taken and I'm very sure I've passed which is all i need for my college course 0 -
I agree.
15 (C) Biological Explanations
What did ye say for the breasfeeding one and the person's fingers turning white?
Said that as long as a breast pump or baby is used (lol) the breasts and body will be stimulated to make more milk, were as if the mother does not breast feed, her body will stop lactating, because the milk first made is not ebing used up.
And as for the fingers turning white I just said blood here is cooled quickly, making the skin lose its color and stopping blood from flowing into the fingers. Bit of a silly Q....0 -

I don't know about the blood cooling, the body has to keep a constant internal temperature so the vessels contract to avoid losing heat. That's why fingers turn white. The blood never cools, if it did the cells wouldn't work in optimum conditions...and if it stopped flowing into the fingers they'd fall off!!!
It's the opposite to how the body reacts when it is too hot-at which point the vessels dilate to lose heat...
At least that's what I thought anyhow 0
