As for the rest of the question I remember saying starch was negative as it didn't turn black blue everything else was positive.
Glucose was pink strip
Calorimeter used so it can give Au and the concentration

I put noradrenaline down as well but i thyroxine for metabolism instead

Original post by Elliefggj

What did everyone get for the change in number of people tested positive for testosterone???

i got 58,000 but reckon there will be a big range with answer

Temperature was the. Independent variable and oxygen concentration was the dependent

Time was the independent variable , don’t remember dependant variable

Both globular proteins

I also wrote that 1 prosthetic group per polypeptide not sure about that tbh

For the veins one i talks about them not having much elastin so unable to stretch having collagen

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

The compared the haemoglobin one
Similarities
Made of different amino acids not repeating units
Both conjugated

Difference
4 polypeptide chains not 1
4 irons not 1

Reducing sugar

i wrote cortisol for the metabolic one but i think i put adrenaline or nor adrelanine whichever one that wasnt already in the table

It wasn’t this, you had to take the percentage of each because the question asked for the change in positive results, it was like 200 and something

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

Loads of ppl getting 36000 for people teasing positive for testosterone and I don’t know why

Agreed! But I put protein rather than amino acid🤦🏼*♀️

264nm^3 for volume not occupied by iron
For the letter question on photosynthesis i got:
Ribulose Bisphosphate
Triose phosphate
Fatty acids
Amino acids
