for the microscope question it said 'with a prepared slide' so I thought we did not have to detail the preparing of a slide, we assumed it was already done. I just talked about using the coarse/fine adjustment knobs and using a higher objective lens (I hope thats a thing, last did microscopes in year 9!). I also thought this as it being a 4 marker, it didn't warrant details of preparation (that's more six marker?)

I wrote that a narrower capillary allowed for a smaller, and therefore more exact and accurate measurment (mm). Not sure if that's right tho.

I wrote the same thing

so it was capillaries for the water, which is technically blood?

i put small intestine and blood i think they will accept it

for some reason i got 2,150,000 for the real object size question , what the fucj???

Omg did you convert the mm to micrometers and divide imagine size by real size of image

Nitrate ions. Three questions on ****ing nitrate ions. I can’t oml

The question on nitrate ions was literally the same as the last question on the specimen paper. Guessing its gonna have the same mark scheme too...

(nitrate) ions are absorbed by
active transport
(active transport) is the
movement of ions against the
concentration gradient
(active transport) requires
energy from respiration
(respiration) requires oxygen
no / little oxygen / air in
water-logged soil

If i was an examiner I would give you the mark, but AQA can be quite specific. At the end of the day it was only 1 mark if you have lost it.

I got 10.4 too

Original post by Dissapointment

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

it's not the same but it's something similar it has nothing to do with osmosis. it's a metabolic reaction

I got 10.4 too

i got 0.88 cuz i find the rate per minute so i divided

yep, hopefully grade boundaries are low as most people found it hard

Was that the question about what the findings show us about how nitrate ions are absorbed? 4 marker, second to lsst question.

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
