  1. I also did options G and H and I think the paper was quite easy but I was surprised that the Bohr Shift came up. It was a 6 mark quesion and in the revision guide there's literally only like a sentence about it. I just wrote about CO2 concentration increasing in respiring tissies and pH falling so hemoglobin releases oxgen. I read the other options, and i looked at the evolution chapter, thought, meh not to bad, microbes chapter always looked difficult, looked at chapter H and i saw the Bohr Shift question and i though lol, im glad all i have to answer is brain scans and rainforest conservation. Like, the conservation of the rainforest, was the one thing i knew 100% and exsitu and insitu conservation, those were the two things i had revised hardcore, and for E, I had also been reading about the bird song template which i didnt really know prior to my 1 day berfore studying. Got really lucky on that one.
  2. although i messed up, i was done like 15 minutes before, so i checked my answers, but then when i left the room i suddenly realized i had done a terrible mistake, when measuring the distance the ant had traveled, i used my coincidincally 100% correct sized pen cap, to measure the 20cm incremenets, and i was like ou i fit 2 and a half of my pen cap half of my pen cap =5 yep 45, im a genious, move along. left the room, it struck me, 20/2 = 10.... NOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!
  3. EAAASSSEE MODE!!! I had studied all day and night, and i was prepared for the worst! but BOOM! it had all the right questions, and the one about the ant... I had done a bio lab about ants and locating food, which i did extensive research on and also got top marks on, so i knew all about it. it was perf!
  4. ^THIS^ Please! I've hear 3 is the supposed answer :/ :'( i put 7, i tried to look for a time when they were lined up... but i couldnt see anythang ...
  5. yes but during the exam i thought... well plants need Co2 but bacteria want oxygen, things usually dont flock around to help, its to get what they need and it just happen to be a mutualistic relationship then i guess (yeh i done my reading on chapter G). I don't see a benefit for the bacteria to a place where it can give off Co2 to a plant when it can give off Co2 where ever it feels like it, of course i could be mistaken
  6. That there is most photosynthetic activity at 450 what not nm and that the aerobic bacteria like that
  7. I also chose that one, other answers didn't seem valid. Is it the one with 'somethintsomething axons of the neuron somethingsomething'? yerp, but it feels weird to say affects the permeability... but i guess its true, neurotransmitters attatch to the receptors thus making the membrane permeable to ions like aquaporins increasing the permeability of the collecting duct
  8. it was that if they were in same class they belong to same phylum or something like that I wrote shivering too!!! HAhaha couldn't think of any and yeah I put that phylum thing too was it answer A? Think it was C..cant guarantee that though yeah im doing option G, worst option ever! Really? I'm also doing option G, but I think it is one of the easiest topics! On the other hand, I absolutely hate my other option, option H :| its quite easy but its really boring! and i love option H haha The thing is, its too easy, or like, i just say yeeah yeaah of course ill know what water, soil ph and salinity does to distribution of plants or outlining conservation methods, and when i try to answer it properly i forget or like quadrat method and transect, im thinking its easy but i struggle to phrase it well.
  9. Maybe many people think this question was easy, but i became very unsure - it was about the function of proteins, i was stuck between either as channels to allow other proteins to diffuse through membrane, or to hydrolose Atp to allow for transport or whatever against the membrane, i chose the latter but somewhat unsure..
  10. Well, i have to go back to my studies, would be ironic if IB survival made me fail my paper 3
  11. but it said identitical, it cant have been meiosis 2... there are 4 different end results, im pretty sure its mitosis only, although crossing over does not occur all the time there is random orientation and stuff going on, there is that joke in the biology book about the twins looking alike... dry humour Wiii, awesome, but I asked my teacher and she was like "that's wrong". But in meiosis 2 the sister chromatids separate and those are supposed to be identical if it's not for crossing over and such stuff? Well if your teacher told you so :/ genetics was never my strong side... but i mean the genetic chapters talk so much about there being an INFINITEE AMOUNT OF VARIATION 2^23 and all that, 8mil combinations in just the random orientation part, and then adding crossing over, and yeh, i dont know but i feel mitosis is right
  12. what were the choices? i think the answer was somtehing like it doesnt produce antibodies
  13. but it said identitical, it cant have been meiosis 2... there are 4 different end results, im pretty sure its mitosis only, although crossing over does not occur all the time there is random orientation and stuff going on, there is that joke in the biology book about the twins looking alike... dry humour
  14. on a slightly unrelated topic, anyone doing option G? uuugghh i am not looking forward to writing about niches as human impact blah blah... stupid seals and their stupid temperature difference it was that if they were in same class they belong to same phylum or something like that I wrote shivering too!!! HAhaha couldn't think of any and yeah I put that phylum thing too was it answer A? Think it was C..cant guarantee that though
  15. i said it could have a layer of fat underneath the skin and thick fur man :/ i was thinking of that too, but then pressure was on me, i was first thinking oh it can have hairs stick up.. but then i thought no hairs dont work in water maybe, and then i thought what if it gets really fat, but there is nothing i can remember in biology about fat insulating heat, your answers sound better though than shivering...
