<p>@xiaohyolee: got the same answers that you did… for I think all of them! (But I took eco)</p>
<p>anyhow, I thought the test was very easy (finished in 30min! wooo) but I’ll refrain from guessing my score
there were a few more that I’m not sure about… maybe they were already mentioned?</p>
<p>Kidney Q (dialysis something or rather)- wastes?
Tree Growth Q- growth occurs between first and second branch? none of the option made much sense to me.
Female Reproduction Q- got this one wrong, should be right before ovulation or about 10 days after period ends</p>
<p>@koken: nope, bmr is dependent because the value <em>depends</em> on the temperature (independent). I.e bmr changes, does that change temp? no; but if temp changes, does that change bmr? yes. hopefully that clarifies it a little? >>;</p>
<p>Can somebody explain why it is 35 to 45. I could have sworn the the Starling expanding most in the 45 - 55 range (or maybe I am thinking of a different question).</p>
<p>^^ the question was range during which starling expanded MOST. so yeah it did expand in 45-55 range but the diff between 35 line and 45 line was the greatest</p>
<p>we established that the tree grows because of the development of the meristem (sorry xkaeze =/)</p>
<p>as for wildy, 35-45 because that was the point during which the graph displayed a huge increase of the spread of the population of starlings…perhaps you just misinterpreted, but it was a much more noticeable difference than any of the other years</p>
<p>For the starling thing, it’s definitely not add a new exotic species. That would just lead to an overpopulation of the new exotic species. I put relocation because I didn’t think that it was very politically correct to come up with a virus to kill all starlights. Just like, an sat answer will never seem racist or anything (or at least I hope so). Plus, yeah, the virus could mutate or wtv and infect other populations or end up wiping out Starlights everywhere.</p>
<p>ughh I got the mendel question wrong shoulda read it more carefully oh well.</p>
<p>does anyone remember the one about what increasing temperature does to enzymes? does increasing temp. increase the rate of diffusion? i dunno it kind of seemed weird… (it was a I, II, III type question)</p>
<p>For the mendel question, I remember I put 1 and 2 as segregation of characteristics was wrong. The first part about the blood was free points. Same with the ending of the m section (virus questions).</p>
<p>does anyone remember the virus and proliferation of lymphocytes or whatever. I picked C; it was something like proliferation of pre existing lymphocyte in spleen. Aren’t B-cells already pre made and it is due to chance that a certain antigen bind to that specific antibody. after, that specific B-cell with the antibody proliferates in memory and plasma right?</p>
<p>For the Mendel’s Law it was:
I. Dominance/recessive
II. Independent assort.
III. segregation of characteristics
i put 1 and 2 cuz wasnt it segregation of alleles?</p>
<p>And does anyone remember the enzyme question with the graph and temp. and concen.
I remember there was like I, II and III
I. was like diffusion of substrates increase reaction?
II. inc temp inc reaction speed?
III. inc. temp breaks peptide bond
I put I and II because i thought diffusion meant the concentration gradient being balanced throughout the solution, and if its more balance, there would be more chance that the substrate would meet the enzyme. And II the increase in reaction due to increse in temp. was shown on the graph? III just wasnt right because high temp breaks H-bonds not peptide.</p>
<p>Also, the sea urchin eggs in [M]. Answer to one question was like abrupt changes after time 2 or just change in time 2. I put change in time 2 since the slope increase in the middle of time 2.</p>
<p>For the starling one i put trap and relocate. My choices came down to introducing a virus, a new songbird or trap and relocate. Virus is just too devastating since it wipes out the entire pop. And introducing a new species to compete exerts too much pressure on starlings and may affect the ecosystem. Too many factors remain unknown for introduction of virus and competitor. If you just trap and relocate you can balance the habitats around the US.</p>
<p>And for those who took [M]. Was carbon the heaviest? My choices came down to either Carbon or Hydrogen. Initially I had thought oxygen, but that wasnt one of the choices. So i picked carbon. Hydrogen makes up most of living systems as H2O, BUT wasnt hydrogen the lightest element? And there was way more carbon to weigh more that hydrogen because every living thing is made of organic molecules, all with hydrocarbon backbone.</p>
<p>For the questions with the leaf and exposing three of them to diff. light settings, one was to kill chlorophyll (burn in alcohol), the other was like respiration only for the dark leaf. Calvin cycle requires products of light reaction, and photosynthesis needs light, so they are both omitted.</p>
<p>ya im pretty sure right because only the H bonds break and they make up the secondary structure within a protein molecule, which is affected by high temp and plus and this is what wikipedia says </p>
<p>When a protein is denatured, the secondary and tertiary structures are altered but the peptide bonds between the amino acids are left intact. Since the structure of the protein determines its function, the protein can no longer perform its function once it has been denatured. This is in contrast to intrinsically unstructured proteins, which are unfolded in their native state, but still functionally active.</p>
<p>Does anyone else feel like they did really badly on this test?</p>
<p>Anyway - are you guys sure the answer was trap and relocate? Because I really think introducing a new species was the more practical answer — but i’m not sure at all.</p>
(But I took eco)</p>
shoulda read it more carefully oh well.</p>
