1. I don't think that was right. Sorry. Join the club.

2. Not sure on the first part of the question.

3. I put a similar advantage but for the disadvantage I said that the old machine was less portable and more expensive to produce. No idea if this is right.

I also put that. I think it's right.

I am pretty sure that was a heart. First question right?

No the one on the lungs; question 4 I think ; had arrow obit and one way in,
loads of circular things in what looked like the alveolus and one way out, with arrows flowing out! Surely it was the lungs with artery, capillary and vein?

For the first question did we have to say left and right?

No, you won't have to. You will get the marks for just naming the chambers.

I was temped to note that the old dialysis machine looked like it would probably shop you in half and be extremely likely to explode at any given moment. This was probably not going to be relevant though.

I messed up on the humidity/marathon runner question - i said as it is humid the blood gets hots and so it detected by the thermoregulatory centre, it then recalls the temperature but can't cool the person down to the humidity. - what on EARTH is WRONG with me!!!!!

Hahaha, at least you answered it. I just couldn't work it. Until after the exam

I have no idea what UMS is. How many UMS is each paper out of?

UMS stands for Uniform Mark Scheme. Found this person who explains what the UMS is well: http://uk.answers.yahoo.com/question/index?qid=20110108064931AAfz7yg

Each of the paper's has a top of 100 UMS, as does your ISA paper to give a total of 400 UMS for the whole GCSE.

I hope so, completely forgot to write left or right.

Yes it has because the glucagon made in the pancreas will make the glycogen break down to glucose in the liver. The glucose is then released into your blood causing a higher concentration of glucose.

Yes but it was about a blood vessel being connected to the heart

What did you all put for the one about how the 2 ventilator machines were different? :smile:

What would 39/50 on biology ISA be in UMS?

was the very last question asking us to talk about how glucagon was secreted by the pancreas and taken in by the liver to produce glucose from glycogen and then put into the blood?

I hate to predict these things, but I expect the A* mark will be no higher than 50 at most. It depends on the politics of it all. I predict 48 as an A*, as it was a quite hard exam paper with rigorous topics on.

What was the answer for the marathon runner? Im not sure about my answer, i wrote, because the weather was humid the sweat couldn't evaporate and carry away the heat. So when the blood vessels dilated the heat got trapped in the sweat causing the person to ever heat

There's no way of knowing until August when all results come out. If you want something for a reliable(ish) guess, double it. Although, usually UMS is easier to get than just through doubling. Maybe take away 3.

For the ventilator machines i put that the iron lung generator breathes for the generator but the modern one doesn't, is this right?

Does anybody know what was the other thing the tadpole needs in the water? Was it oxygen?

I think the grade boundaries will be quite low as there's a lot of disagreement on here so it sounds like lots of people got lots of different things! :smile:
