I think it was to do with osmosis and how as people with diabetes are unable to control their blood sugar levels they had higher concentration of sugar (so lower concentration of water in the blood than in the cells). Therefore, the water moves from a high to a low concentration through the cell’s partially permeable membrane.

Same. I was initially thrown off because glucose was lost via piss, so I thought concentration would be lower

********. Every single q was a fxcking practical. Everything I revised for never came up, exaggerating but still smh.. load of shxt if you ask me, triple was easier apparently

lol i fuxk knew it my teacher told us that they will put LOADS of practicals so we revise only those

wtf was the cube sh*t with diffusion? All i did was calculate surface area and volume for each cube and wrote everything i knew about diffusion

it was sa to v ratio B1 gas exchange

some of my maths ones were 400 for the microscope one, 3.3, 91 and 10.4

it was two significant figures

I swear the magnification one was 4000, had to change cm to mm? 24/0.006?

I am actually really positive about the exam. Everything I revised was on the paper, so I was happy with that. The only thing I didnt revise was the last questions on nitrate absorption in plants.

The paper was alright. What did everyone get for the cube question.
I calculated the volume and surface area

Yeaa diabetes means there is high blood sugar level meaning high conc of sugar in the blood therefore there is less conc of water in the blood in comparison to the water in the cells so the water from the cells move out of the cell into the blood by osmosis through the cells semi permeable membrane

Apparently it was to do with osmosis. I have no idea though.

For how to make the photo synthesis one more valid I put use Gad syringe matead and get someone else to repeat the experiment and check if results are similar. Is this right
