answers to questions that tricked people
VCAA does not allow powerhouse of the cell as the proper option - people have lost points for this in the past
Red blood cells (RBCs) are NOT nucleated
In a hypotonic cell concentration of solutes is low and concentration of water is high
In an isotonic cell there is movement of water across the membrane, just no NET movement
osmosis is diffusion of water - you would not describe the movement of any other substance as being osmosis

Some trick questions in there haha

rip. I totally forgot that red blood cells are a thing
That's alright, you got almost everything correct so you're allowed to have some leeway :)

Congrats darkz!

That was great!
rip. I totally forgot that red blood cells are a thingI wound't worry about them - they aren't important.
