limewater

How was the igcse biology edexcel paper 1?
What did you write for the question that said how does the Lactobacillus help produce milk?
And the one that said how does trained person run faster than untrained?

lol no my 6 marker was on ivy plants. how was ur paper tho

Same, what did you write for how does the Lactobacillus produce milk

Do you remember what answer you put for the question about what liquid would be in the test tube?

PARFINN OIL? Is that it

what did ym put for that red blood cell in distilled water one and the red blood cell in salt solution one

I waffled so much, still don’t know the answer

i found the exam so hard and everyone in my school found it hard as well

@drk2 what did you put for the answer about the touching a hot pot, I think it was asking what it was called? I put reflex arc but idk if that’s right

pretty sure its cos it dont have a cell wall so the cell bursts
not sure abt the salt solution one tho - think the water moves out and cell becomes plasmolysed

what did ym put for that red blood cell in distilled water one and the red blood cell in salt solution one

reflex arc was in the qu wasnt it - i put involuntary action or smth

Bro for the first part I talked about the cell wall retaining the red blood cells shape , when the water moves in by osmosis the volume increases and when it eventually leaves the shape will change . Bmt paper 2 academic comeback
