what i did and really made me more confident with the paper is that i did 2-4 past papers and recorded my results and look if you get more than 35/40 without revising then ur doing great and the 5 marks you lost you could then dig out those topics and then flick throuh the notes to refresh ur memory about it anf i guarantee u'll do great. Gd luck

ok man its not a problem and its simple look first of all the digestion starts in the mouth with chemical and mechanical digestion. Amylase is used to break down starch to glucose and theeth is used to grind and chew food. Food is pushed down the oesophagus through perstalisis then enters the sotmach chemical digestion happens here... Pepsin breaks down the protiens to amino acids and HCl is used to denature the amalyse from the mouth.

I Hope it helps!

It's A cuz when sewage enters the river it promotes growth of algae and bacteria feed on them;use up a lot of oxygen. But as u go downstream most of the nutrients in the sewage r either used up or fed upon by bacteria......so the groeth of algae and number of bacteria decrease and this restores the level of oxygen.

Tell me if u didn't get it

Bio paper 1 is sooo easy. Last mocks i got a 39/40. The question I missed was the energy pyramid thing. I mistook it for biomass.

The table shows the percentage of protein, fat and carbs in 4 samples of dried food.
Which has the highest energy

     Protein      fat      carbs
A.    76           9         15
B.    17           0         83
C.    33           32       35
D.    15           85        0

I said D. Is that the correct answer?
I lost the first page so I dont know what year it is. Can someone tell me which year and month the paper is?
