  1. It's pretty much impossible to get a zero; even a solid structure with a clear thesis and some accurate knowledge can gain you like 5-7 points easily I have no knowledge about that subject since I didn't study it, but hey, if half the information in the essay is correct you could gain some points obviously, but you may be held back in the fact that you "misinterpreted" the question; although you didn't really misinterpret it, you just talked about the wrong thing (possibly out of context?). Don't stress about It I would say; I'm sure your other essays can maybe make up for it
  2. Lol i know!! We did those options mostly 'cause it fits in with some of the core stuff. Haha, same here! I was hoping there wouldn't be any Hemoglobin oxygen curves and explaining them I was confused with why the bird song was 6 marks Ahh i hated the rat question!!! What was with all those extra rat groups? Unnecessary info much I think the bird song question will be rather broad in the mark scheme, I was really surprised to see it be assigned 6 marks too. I scrawled down a whole page of information hoping I hit on enough points! These data based questions were actually some of the worst I've

  4. This paper was a dream! I did option H and E as well , everything I didn't manage to cram in wasn't on the paper.. I was screaming internally. The data base questions definitely weren't as easy as some other years, like those damn rats.
  5. I put those same answers to those questions too and yes, it was the interstitial cells (aka Leydvig cells) and yes they produce testosterone Yep, loop of Henle.
  6. Q1: I put anywhere within the axon. I asked a few people and they said this as well, but I am not entirely positive! Since all of answers had only one option except for the answer that said "all of them", I leaned towards it because I was fairly sure it passed through the entire axon! Q2: I put maltose, amylase breaks down starch into maltose and the maltose is then carried to the embryo Q3: I am fairly certain this was tertiary structure; since it was referring to the 3D structure of one polypeptide (which is due to the bonds that form between the R groups of the individual amino acids), thi
  7. Q: Stem Cells My Answer: I said that they can be transferred between organisms. I honestly didn't really know whether to pick that or the fact that they reproduce, all I remembered was that they have the ability to divide endlessly I was caught up on the word reproduce, since they don't really reproduce they replicate themselves by dividing. No clue. Q:Q: After one phase of meiosis of a diploid animal cell, what are the products? (doubting whether this was even a question.. cant remember) A: I can't remember what the exact answer I put was, but it was the one with chromosome number: n instead
  8. Hi, What I found to be really important when I was completing my IA labs was to be as thorough as possible; on my first few labs, I would always be scoring half of the points (3/6) in each section just due to stupid mistakes. You really have to focus and read the rubric very carefully, because my teachers were very stingy in awarding full marks (6) even if you made the slightest of errors. What really helped was that my teachers in both Biology HL and Chem SL provided us with a solid breakdown of the rubric, outlining exactly what we had to do to bring our labs to the next level. Has your teac

  10. What did you guys put for the food chain question on P1? I said it was both a secondary and tertiary consumer and hoped I was right because I barely studied ecology..
  11. I know for sure I got that one wrong ! I didn't really understand what it was asking and didn't really understand the picture that was given so I guessed all three... I think some people in my class said just replication, although I heard replication and transcription from a few people as well.
  12. I believe it was ruler mag/scale mag, which gave something like 64mm/400 or whatever the magnification was for the actual size, and +/- 0.0025 for the uncertainty...at least I hope that's right lol That's what I did as well (except I measured 65 mm oh well ). I believe I expressed it in both mm and micrometers because they didn't really specify how to express it, and I'm so used to expressing actual size in terms of micrometers... hopefully they don't ding me
  13. I put emergent properties, hopefully that was correct because that was the only thing I remembered seeing in the outcomes and it seemed to fit Also in response to your other question I believe it was the germinal epithelial cells, as it pointed to the very outer area of the seminpherous tubule. The other arrow pointed to the interstitial cells.
  14. As long as you explained the synaptic transmission well I can't imagine that will cost you too much Also yeah I remember that question, I knew the order but it was easy to be tricked (#17)
