For the high blood pressure I put, there were more blood cells which had to be transported per second, so the ventricles contracted more strongly, increasing blood pressure??

i just put down, greater no. of red blood cell, great volume of blood.
guys it's a one marker :s-smilie:

I know this is unrelated but worms don't have spiracles instead they have a different form of haemoglobin which I found interesting since I assumed them to be of the insect ancestry. So we're related closer to worms than to insects.

yeh i know :confused:

if i metnioned worms at any point it was a mistake.

yeah.. i just said if there is more EPO (or whatever it was called) then there is increased red blood cell production so a higher concentration of red blood cells so a higher pressure. it was a bit of a weird one.

i definitely got the DNA strands question but it was only two marks, i'm more worried about the last question, i can't even remember what it was about now but i wrote the completely wrong answer for sure :<

Lol I got the same .. Except percentage increase :/ I know mines wrong though lol & hmm hope for the best.. Got the last of my 5exams of the week & same psyb2? Right...

Well I put 1.5% then I realised I needed to times it by 100, though it could be wrong altogether. I just hate the questions that require a lot of application - there was one about small eggs and evaporation of pesticides - I said it would diffuse easier as a gas but just made it up. I don't even know what psych paper it is! I know it's got psychodynamic, learning and the biological approach on it.

What did people put for the table questions the one about DNA, did each row have to add up to 74???

And was it same number for A and T and C and G????

Cheers.

I didn't put anything like that! All I put was that it was dissolved in salt solution that leads to high blood pressure. Dunno if I'd get a Mark because I wasn't technical about it!
