Edexcel GCSE Biology Paper 2 (Higher) - 9th June 2025 [Exam Chat]

if I put repeat the investigation for the one with the maggots will I get a mark

what did ppl put for the three factors reducing food thinf

where did lil bro get war from idk what question ur talking about but if it was about the insecurity one i put increasing human population increasing consumption of meat and fish and then new pests and disease

but i also said it was ripe too just incase to help my answer idk

30mm because it moved 10mm from 20

no that’s if ur investigating how temperature affects rate of respiration which it wasn’t. the improvement would just be to include a control with the same set up but no maggots

what did u guys get for rate of decay or smt where u had to give it to nearest whole number

for the glucose test i wrote turns green would that be okay... ,, also for the graph what did people plot on x and y axis? 1st 6 marker i yapped about the spike and normal person blood glucose goes back to normal after an hour while diabetic took 5 hours and food intake/fast period and i explained about diabetic having no reaction to insulin etc. and for the 2nd 6 marker i wrote about hypothalamus detects higher water so less ADH and then less permeable kidney wall so less water absorbed and more waste water in urine/ urine becomes more diluted so body can lose excess water i also mentioned to prevent cell lysis and stuff just in case. also for the menopause question what did people write-- i did figure decreases and then i explained magnitude of decreases just in case

I mixed up the negative feedback for the last question and said that more ADH is released and the collecting duct becomes more permeable and my answer had all the content but I’m not sure how many marks I would get for mixing it up? I assumed the answer I wrote would be capped at 4 marks (level 2)?

i did the exact same thing !!

chatgpt says you’ll get 1 to 2 marks!!

That question was on 2024(it was about urea,protein and glucose though) and the answer was state and explanation

10% I think

and for that one multiple choice question it was like what is the control variable or smth and the options were incubation time volume of milk and stuff what was the answer

What did u guys write for the proximal convoluted tibule question
Cuz I just said selective reabsorption happens by active transport idk if that’s correct tho

For the last question did u have to talk about the fpdangers of overhydratioon

does it matter if i did it the other way round
