very helpful!!!!

yeah nice one

useful seen as i need to do some last minute revision for the test on monday!!

Very useful! Great resource for quick reference before the test. THanks X

woo

even bitesize doesnt have triple science revision

"snarles"

but thanks =)

Good revision but diffusion isn't through a partially permeable membrane, that's osmosis.

great help

this is great thanks - do you have any more for the rest of B3???

really really helpful

Good. A lot of writing but it did help me.

Thanks! great stuff :D

Quite helpful but a partially permeable membrane is osmosis and diffusion is just down a concentration gradient :) but still helpful

i love youu :)

haha thanks absolutely fantastic!!

But yeah as other people said, diffusion is the net movement of particles moving from a high concentration to a low concentration (across the concentration gradient) whereas Osmosis is the diffusion of water across a partially permeable membrane.

Brilliant :D

Good but missed out a lot about the kidneys which is needed a lot for B3 further biology,

for example dialysis and transplants pros and cons,

why some substances re in urine and not others, the effects of a faulty kidney, like protein in urine

other than that very good powerpoint

i am angry how bitesize provide no materials as they were my life line for the past two in each p1 p2 c1 c2 b1 b2 so that sucks

Really Helpful. Thankyou =]

thanks :D
