<p>yup i remember from barrons, haha we took the same test cory</p>
<p>pretty sure climax community has stable species cause climax communities dont change for long long times</p>
<p>Is the bio curve around the same as the USH curve relative to the # of questions? It takes quite a bit wrong to go under 700 right? How many wrong would a 750 be?</p>
<p>the curve is very steep, 750 is only like 7 wrong</p>
<p>alright that's good. I'm counting 4 so far, but it could be as many as 8, which would still be pretty ggood for me. As long as i'm around 750.</p>
<p>Does anyone remember how the question for huntington's was worded? mother had none of it in her family, was father Hetero or Homo for it?</p>
<p>mother's family had no history
huntingtons is dominant
father was heterozygous </p>
<p>i believe</p>
<p>I agree with most of ooka's answers</p>
<p>I'm not sure but could someone explain why the ultrafilter one is virus? I put bacterium...</p>
<p>I also think most of our food comes from grasslands, I mean wheat, rice, corn, other grains etc aren't grown in tropical rainforests, and tropical rainforests have a much lesser biome distribution than grasslands. It could be temperate decidious but I guessed grasslands anyway.</p>
<p>I've already missed 2-3 I think =/</p>
<p>For the last one (M) I put that some bacteria developed resistence since answers like that are usually correct but normal levels make a lot more sense</p>
<p>On one of the core questions I didn't read one dish was on its side so I missed the gravity answer, although the other one was touch for sure and the third answer was regulated by hormones</p>
<p>Pretty sure I missed some PTH ones since I hated that graph =/</p>
<p>For a genetics one with a huge cross I put I II and III not sure about that either</p>
<p>I hope -6 > 740</p>
<p>I took E...always thought I would be taking M, but then on the drive to the test I did both the E and the M on a PR practise..did way better on E</p>
<p>*** was the one with the squirrel (or some other animal) signaling an alarm cry when predator is near (it was at the start..i've never learnt behavioural biology)</p>
<p>yikessssss. I wish I took E. I got a lot of those correct....M...:[ I'm scared.</p>
<p>E is a LOT easier.... it was for me anyway, because M stuff was last year (grade 10) and E stuff I just learned from a prep book before the test</p>
<p>and what was the one with individuals 5 or 6? I put only 6, because it didnt say whether the allele is dom/rec</p>
<p>did one of the questions ask which are on the same trophic level or which are not?</p>
<p>The squirrel sounding an 'alarm' to others, possibly endangering itself was ALTRUISM.</p>
<p>Huntington's disease is dominant, so you only need one copy of the allele to get the disease. I forgot if the dad had it or not. If he did, and I believe mom's family was clean, the kid's got a 50% chance.</p>
<p>on E? yea.. there was some 5L glass container that they put inside 5cm of soil, then 1/4 of the bottom surface area was covered by a rotting piece of wood...then they put in grass, clovers, salamanders, crickets (or grasshopper, not sure), and earthworms. AFter, they put the tank by a window (sunlight) and sprinkled the soil with water persistantly to keep it moist to the touch. THere were a few questions about it..one of them asked how many trophic levels there were in this community. It was three (producer=plants, 1st consumer =earthworm/cricket, 2ndary consumer=salamander)</p>
<p>Also, there was a question that asked what woulld happen with the O2 and CO2 levels if a top was put on...does anybody remember what they put for that?</p>
<p>damn..i got the squirrel one wrong..also skipped on the deutrosome/autrosome one (*** are deutro/autro???)</p>
<p>vadox:</p>
<p>It had to be 5 and 6, since the trait is autosmal recessive both parents have to contribute an allele to a zygote in order for the child to have the trait</p>
<p>Definitely!!!</p>
<p>@lalala06: i guess it asked what are not
i chose the wolf and sheep one</p>
<p>wow, im so dumb, i put what were on the same level</p>
