Heart rate was 86.
One percentage for something was 36% but there will be leniency.
36000 for something else
264 for the volume one.
I put veins are closer to the surface of the skin. Not sure for the other 2 marks
It's a conjugated protein as it contains a prosthetic group of iron

I wrote both contain Fe ion prosthetic group
What was the other similarity between Haemoglobin and the other protein?

I put that they were both conjugated proteins but I guess that's what you mean when you start talking about prosthetic groups :/

I think it's noradrelaline and cortisol. Aldosterone increased blood pressure but I don't think it dilates pupils .

I put noradrenaline and cortisol but think noradrenaline is wrong

It wasn’t 36000 because you had to calculate the change in POSITIVE results, not the change in number of samples. Therefore you had to do the percentage associated with that year for the number of samples to find the number of positive results in the two years and then find the difference, it was like 265 or something I can’t remember

For the body builders veins:
Talk about structure of veins, layers of smooth muscle and elastic fibres.
Main point is: Veins go towards the heart, not away. When exercising blood is pumped away from heart to the muscle so it can not be veins.

The mechanism was CO2 binds more strongly so gives up the oxygen more readily this is known as the Bohr affect

252 (I think) for the number of change in people testing positively
Noradrenaline and cortisol in the table
Atrioventricular value as the valve that shuts.
86 - heart rate
Photosynthesis - light dependent because needs the reactants of ATP and NADP to oxidase GP to TP
RuBisCo as the enzyme
Auxins - Rooting powder and weed killer in broad leaved plants
Gibberellins - seed germination
Anabolic steroids - steroids can cross plasma membrane that’s why can be applied to skin
Veins presents as arteries run close to the organs supplying them with oxygen
The multiple choice the cells were red blood cell and white blood cell

Wasn’t 263 already in manometers or was it in milimeters
