[QUOTE=jackcoys;65688547]The mark scheme was just sugar is added to yeast and mixed in warm conditions without oxygen present (anaerobic conditions) which produces ethanol and carbon dioxide. 6/6 ah yes thats right, i actually remember it now! wouldnt mind it coming up again 😆
i love chemistry and had a great teacher so if you need any help i'd be happy to help! 🙂
Thank you!! I love chemistry too, I want to take it to A Level so I'm so annoyed our sub didn't go into any detail in any topics! If I get too stuck I'll message you
What did u get on the two suggest questions, suggest how immobilisation prevents against disease and suggest how loss of leaves helps tree quiver
for the immobilisation one i said it stops the bacteria spreading and makes it easier for phagocytes to engulf them and for the tree one i cant remember sorry

Yea i said it allows them to be engulfed by phagocytes, hopefully that should get the mark?

yeah definitely! the one with the trees was that the 2 marker suggest question on why they drop their leaves when there is a drought? if so i said they did to survive by conserving water or something
