how many marks does each question carry?
Usually 1 mark per question. A few tests will subtract a mark for a wrong answer, so watch out for that – but not too common.
Can someone explain why answers for 5 and 6 are from a lesser concentration to a higher??
I thought because solutions seek to be isotonic, that solutions would disperse to move *from* a high concentration *to* a lower one (and therefore be balanced on both sides of the membrane, or generally be evenly dispersed if not across a membrane)
If they’re moving from a lesser concentration to a higher (like the answer key says, twice) wouldn’t that be a form of active transport? and therefore not be diffusion/osmosis, which are both passive??
Osmosis goes both ways to equalize – diffusion goes from greater to lesser
good point – could be interpreted either way — During prophase and metaphase of mitosis, each chromosome exists in the above state. For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase)
Thank you so much Brian, these tests have been so helpful!
