AQA GCSE Combined Trilogy Biology 8464 - Paper 1 - 14th May 2019

ummmm...

"Plants need nitrate ions in order to make proteins.
A plant is growing in soil flooded with water.
Explain why the plant cannot absorb enough nitrate ions."

That was literally the question we had no?
It was asking about why the one with oxygen bubble through it took in more nitrate ions and faster

Easiest test of my life. You guys must be stupid to think this was hard.Idiots!!!

mate there was no water = no osmosis. the question asked about how nitrate ions make proteins fro growth

What was the awnser for the graph question where they gave you the graph asking for rate per hour, I got 10.4 but I know someone who is predicted a 9 with 9.6? So idk

mate there was no water = no osmosis. the question asked about how nitrate ions make proteins fro growth

Nah nitrate ions is bout active transport not osmosis

What did people get for the magnification question and the beta blocker 6 mark?

You must be disabled

Ah no we're talking about different questions.....

I'm talking about the one where u had to compare why one absorbed more nitrate ions than the other.

You has to keep referring to the graph on the other page and speak about how there isnt enough oxygen for the muscles so they go to anaerobic respiration which then puts them in oxygen debt therefore they run out of breath

id remember lol

Easiest test of my life. You guys must be stupid to think this was hard.Idiots!!!

easiest test of my life. You guys must be stupid to think this was hard.idiots!!!

what are you on about?

what question was it? i dont remeber

I also got 10.4

It gave you a chart and you had to explain why one absorbed more nitrate ions than the other. one was bubbled with oxygen, one was bubbled with another gas that wasnt oxygen
