Google image a diagram of the heart, it's definitely the atria that they go into

I don't mean to be rude but i am 99% sure that the veins travel into the ventricles :s-smilie:

What text book are you using?

I can confirm that Pulmonary Vein goes into left Atrium and Vena Cava goes into right Atrium.

How did you find the exam?? I thought it was quite hard and so did most of the people in my year group :-)

Okay actually, some questions were quite hard and I almost mucked up the second 6 marker. We shouldn't talk too much about the answers until after midnight because otherwise people who haven't taken the exam may do better, and lift the grade boundaries, imagine being one mark off a grade! :/

It was an okay exam, but I was expecting it to be hard, considering the unnatural ease of the B1-3 paper

What do you think about what I wrote:

The fan increases the movement of air particles, which means that water molecules can evaporate into water vapour. In A, there will be no mass change, because of the oil, which will inhibit water molecules from evaporating into the atmosphere. However, with B, mass will decrease, as the plant will move water up through the xylem to the leaves, where they will be exposed the high movement of the air particles, and hence evaporate into water vapour. Hence, A will not lose any mass, whereas B will continuously lose mass due to the continuous transpiration pull that brings water to the surface of the leaf, where it can evaporate.

The hip joint is an example of a ball and socket joint. As a result, there is a large range of movement available in all directions. Norman's joint, however, is very large, which means that there is less synovial fluid. Synovial fluid absorbs shock and acts a lubricant, preventing friction. Since he has less synovial fluid, there will be more friction opposing his motion, thereby leading to him having a smaller range of movement.

yeah that was what the majority of the people in our year said as well, a lot of the questions were about analysing graphs

Ah, we all thought it was fairly easy. That one question about 'partially decomposed dead material' though — we both put "detritus" instead of "humus"! :angry:

I thought it was... I don't even know. Some parts were horrific, some parts were okay... I dunno!!! :frown:

btw did vase A also have oil over it the same as B??

I hated that exam.

It was about how the mass of water changed between the two flasks, one had a plant in and the other didn't.
How hard did you find the exam?

so what are the grade boundaries going to be ... are they going to be like 90% for an A* out of the total 208 marks how much do u need for a c?

It's roughly around 65% on this paper for an A*,
not sure what you need for a C :-/

This paper's level of difficulty was very similar to that of the June 2013 paper, so I'm placing my bets on it being very similar - or the same - as that year.
