  1. Yeah, that's what I meant -- you count, but the actual trophic name isn't just a number.
  2. I didn't actually take the exam, but I was curious about the Indian song because my friend told me about it, and I'm Indian. I'll have to take a closer look at that, haha.
  3. Yeah, I would also like to say that ab initio exams are by no means "easy". I've taken Mandarin for four years, and I still think the ab initio exam would be a challenge! I can't believe I'm taking the SL exam this afternoon I think you should just take Mandarin B SL. I don't know if IB would allow that, though, since it's a second language to you. You might be able to do Mandarin A2.
  4. Trophic levels don't usually go by just a number -- the grass would be the primary producer, and then all animals after that would be consumers.
  5. Yup, I put 77 weeks as well, and I also spent a good 5-7 minutes trying to run a regression calculation on my calculator before I realized what the question was asking, haha I also put tertiary consumer, but I didn't notice anything odd about the food web. For gastric juice, I said highly acidic, contains pepsin, and is secreted into the stomach. For pancreatic juice, I said slightly basic, contains lipase/amylase/trypsin, and is secreted into the small intestine.
  6. What sections/options did you do? I did G (ecology) and H (further human physiology). I have to say, that was one of the easiest papers I've ever done. A nice surprise!
  7. I said they were linked. I believe that's the type of answer IB wanted, because there was a similar question on a past exam with the answer "sex-linked".
  8. Yeah, what you should do for Paper 3 topics is look in the syllabus at three options that you've studied, and just learn a well-rounded amount of material for each topic. Memorizing just three topics isn't that bad, I've found.
  9. My textbook says that is correct. I guessed that too.
  10. Wow. Four fluent languages. I'm fluent in one, trying to regain lost fluency in a second, and struggling with learning enough of a third to pass the SL exam, haha.
  11. I'm looking at my book right now, and here's what it says (with T and B substituted for the letters in the book): One parent has genotype TB//tb and the other has genotype tb//tb. The four possible genotypes for offspring are TB//tb, tb//tb, tB//tb, and Tb//tb. The latter two are the ones asked for in the question.
  12. Sorry I don't have any advice for you -- but my English teacher warned us that creative pieces are extremely hard to do well for WL2. He said that at the IB training he attended, the examiners there scoffed at the fact that a lot of the creative WL2s ended up being "fan fiction" or something similar. So, if you're going to do a creative WL2, make sure you retain some analytic aspect in it!
  13. Speaking of the recombinants question... here's what I did. They gave you that the recombinants were tB/tb and Tb/tb (or other letters, but same sequences), and asked you to find the original parents' genotypes. My textbook actually had an example with the same exact recombinants, so I remembered that the parents' genotypes would be TB/tb and tb/tb. I'm pretty sure that's correct.
  14. I know you weren't asking me, but I'll answer anyway: I wrote almost two full pages for 4c. Glomerular filtrate refers only to the liquid in the glomerulus. Urine is formed in the collecting duct.
  15. I had a much better time writing WL2, for the reasons you all stated above (mostly because I'm terrible at comparisons), but also because I just threw together a bunch of my journal entries, added transitions and a unifying thesis statement, and called it my WL2. Surprisingly enough, my teacher said it was the best writing I've done in his two years of teaching me, haha
