thymus, bone marrow and spleen are said to be organs of the immune system

Guys I'm pretty sure you have to cut the tubers off the potatoes because yield is the usable part of the plant and tubers are not usable


I thought that potatoes WERE plant tubers.....

oh didnt know that:colondollar:, i wonder how many possible answers there were
No no ive heard that it is possible my paper will start at 1 PM on thursday so anyone who is atleast 4 5 hours ahead me?
Ok guys I don't think we should discuss answers yet people still have to take the exam we don't want the boundaries to be really high :frown: idk wait a day or something

Look like he said some people still might be giving the exam that means that their paper started late and we could have told them the answers but yeah the grade boundaries think and i think its 1b
they have a global schedule doing on the same date and 1b and 1br system to minimise the time difference to max 12 hrs- unless someone from Rio is watching we should be fine
My Paper was so bad... I am freaking out for chemistry on Thursday now :O The questions were super weirdAnd Do you guys know that the growth hormone for control tube was 0 mg!! :/
I so badly wanted an A* in bio but this paper ..... :frown: And I wonder how paper 2 will be cuz paper 2 is always harder!!

which brings grade boundaries down! Im putting exclamation mark here because i want to reassure myself too but never mind!
I really hope the grade boundaries are low... :frown: like in 60-65% for A* :P

:frown: omg why was it 0mg? I had no idea i just guessed a random number

Yep that's what I said! Some of these ions were already in the soil ������


I also said that some minerals were already in the soil in upland or lowland, but my friend said the minerals from the upland place may wash down to lowland, increasing the percentage of mineral ions

controls measure how things are without the stimulus- in this case the hormone, to make a comparison between with hormones and without. But tbh in this case anything lower than 30mg might have been acceptable
what did you say for the potato question?
the dry mass
Lol, next year though this thread will be a gold mine for people who want to cheat on their mock. :biggrin:

Anyways, for the upland/lower land rice I put stuff about CO2 in the air : / and for the secchi dish I put stuff about another april reading being below the line - didn't put the word anomalous though. :frown:

Oh and here's to hoping that the second paper is more knowledge based instead of application of knowledge...
