I got all 3 to be anabolic. In the kidney question i said that it wasn't normal for protein or glucose to be present in the urine...anyone else?

xaoifsx

ah nuts..

pons

what was the answer for 2 features of a denatured enzyme?!
n two uses of a waterbath?

yes that was the right answer!!

flyaway.

I didn't do this question but further back in the thread people were saying that glucose being present in the urine was a sign of diabetes so I think you got it right

I said...

Unable to preform it's job.

Keeping temperature constant

Have gotten an A in all my biology test and got an A in the mocks then the leaving cert came along...heya C- if even. I took a chance and analysed last years papers and ruled out what i thought wouldn't come up. Of course my worst nightmare came true and the 7 chapters i left out came up. i was able to answer the recommended amount but not at all in depth. Those questions were awful ecology wasnt nice and where in the world was human reproduction and breathing and nutrition and THE HEART!! That experiment was a load of crap as well anyone else feel my pain

I'm in the exact same boat. A in the mocks and then this pathetic paper comes along. I hope there's uproar.

jkyle

oh cool thanks took me a while to figure it out!

My Dad said UV irradiation

However my friend said spray it with disinfectant - I had an immediate mental picture of a massive heap of compost, and a man in spectacles and a white lab coat spraying it with a tiny bottle of Dettol :pac:

I'm glad I'm not the only one who said "boil"

For the duck one I said to reduce competition for food and shelter since they'd be more spread out.

I also thought the genetics question was a -lot- nicer than the other years.

I had a mental picture of my mam at the cooker boiling compost. :P

A couple of sources on google seem to be saying you roast it in the oven.

Haha! Me too - sort of stirring it on the hob in a colossal saucepan, "Stick a bit o' compost on there!"

Yeah he said that too. Personally, I think our boiling method has great scientific merit :cool:

That paper was the oddest paper I've seen. I did well in Section A & B. But in Section C.... I'm only confident with two questions. Hated Ecology and the last question was okay, but never revised it. i just waffled. I was expecting for Human reproduction and skeletal and muscular system to come up. never did.

Alibear

Paper is now available online - http://www.examinations.ie/index.php?l=en&mc=en&sc=ep&formAction=subject

Plenty of comparing will be going on in this thread until August!

Yeah the Ecology question was odd

How much did everyone write for the Tension-Cohesion question - you know, just when you describe what happens?

So many definitions in the Genetics question, you know the last bit where it says write a sentence on each. So I just rushed and did the tropism question in the last 15 minutes

I hated that paper so much. Dreading chemistry...

xaoifsx

looking at the pictures..... who in god's name drew them because every single one is terrible. i cant talk but at least get someone who can draw!!!

Alibear

I thought they were fine... Far easier to distinguish certain parts than in the mocks!

Yeah, I skipped that question because I couldn't understand the effin' diagram :mad:

shan007

Why is diffusion alternatively known as passive transport? What did ye say for that one?

Omorish

To be honest, I've never heard of tension-cohesion whatever. O_O Didn't bother doing it. And as for genetics, I never did it...pssh. I skipped a load of parts in question 15. and for ecology, I realised how I almost did every question wrong. I only liked the question with the nephron and that's it ! this is too upsetting... I am dreading chemistry aswell. sigh*

Alibear

No energy is required for molecules to move in or out of the cell.

Iceboy

I must say after looking at that paper I'm now glad I dropped to ordinary, what a strange paper this year, the questions are worded so different to previous years and noting came up up what I studied so im glad

GoldRush4821

Diffusion is known as passive transport because it doesn't require energy. I think people should just forget about it at this stage and move on. No point scrutinising every bit of it..

flyaway.

Ha, I just guessed the passive transport thing. Last night, someone on here on another thread was saying how they wish they could just hit their Bio book against their head and for the information to go in and someone replied with something like ''That would require energy so that would be active transport'' so I figured passive transport was without energy?

Oh Boards. :P

Omorish

just looked at my book. It says. Diffusion is caused by kinetic energy of molecules. These molecules are moving randomly and will spread out of they can. Due to the movement not needing external energy, it is said to be passive.

Ok, I completely answered that wrong.

biggaman

How come everyone's going on about the Ducks? The marking scheme won't have an answer, it'll have something like "blah blah or explained".. if your reason seems valid you'll get the marks surely? :P

biggaman

Also, I wonder is there anyone out there who LOVES biology sooo much that they'd do out the answers???

PJelly

I should stop looking at the exam paper.
I misread the kidney question about the exocrine as endocrine.
Whoops.

Wait, is it not normal for there to be traces of protein in urine? I said yes because urea is broken down amino acids. >.<

Nope, that's amino acids, not proteins... There shouldn't be proteins in the urine.
