AQA Biology GCSE (9-1) trilogy: Paper 2 11th June 2018 unofficial mark scheme

Did u have an invigilator with you in the hospital room? How did u break you leg on the way to an exam? Ahahaha

thats exactly what i did! i got 1.25. 10/2 = 5 then 0.5 x 0.5 = 0.25. 0.25 x 5 = 1.25

For the area question
I see there is a huge chunk saying 1.5 and others saying 1.25

I personally put 1.25 only because I saw that the 6th measurement would not be included as if you include the interval at 10m the quadrat will go over the 10m rule
I its calculated as distance divided by intervals, in this case 10 / 2 which is 5.

I think they're both wrong because it says the quadrats were placed 2m APART. not every 2m

That’s what I did, and I still got 1.25

If you place it 2m apart, so 2m in between each sample, you can only get 4 samples because its within 10m.so the area is 1m^2

This is how I did it, if you put one at 10, ending at 10.5 it makes five measurements, I guess it depends on whether you were supposed to not go over ten meters or not

I did because the reference picture was at 10, so I think this is right but I’m not entirely sure

I didnt include the last one because it said up to 10m. Idk the questions need to be phrased more clearly.

if you put 5 then i think youre fine, tbh this was never explained to me but all my friends in triple said they would have done the same as me

I didnt include the last one because it said up to 10m. Idk the questions need to be phrased more clearly.
