Sorry I said it wrong! Yeah there is a higher concentration of nitrates in the plant and therefore active transport tries to overcome this by going from low to high concentration! Sorry!
If active transport goes against the concentration gradient, from low to high, then would there not be a higher concentration of nitrates in the plant roots? Then the plant uses active transport to get nitrates from the soil into its roots.
if it was low concentration to high concentration wouldn't that mean that there is a higher concentration of nitrates in the plant than in the soil because it needs to move from a low concentration (in the soil) to a high concentration (in the plant)?
Based it on previous years and what has not been asked in a while. B5 and 4 has limited six markers they can ask really. B6 has lots of content so anything could come up.
I got 1:64 , don't know how you managed to get that
Because the TOTAL population is 64,000,000 and the number of people AFFECTED is 100,000. Therefore, the number of people who are unaffected is the TOTAL - the AFFECTED so 64,000,000 - 100,000 = 63,900,000. Therefore, the ration of affected to unaffected is 100,000:63,900,000 (when divided by 100,000 it becomes 1:639).

I said it was mitosis as is produced a zygote which has 46 chromosomes which is the normal number in body cells. I said stage A was meoisis for the opposite reason. I have no idea if that's close to right though.
