<p>Zdub, but didn't the question ask about the method of graphing? I noticed that the nitrogen and phosphate plot data was the same in that graph, but it wasn't a problem with the data representation or the format of the graph, which is why I didn't choose it. </p>
<p>Placenta I put nerve impulses.</p>
<p>yep i put niche. also, for the trees thing i had the second to last one. it was like the bar graph, they had put the wrong growth like they madfe two of them equal that shouldnt be. i thought that was it. but maybe the pie chart was right i dont know. </p>
<p>I put sulfuric acid bc i always heardthat causes acid rain. also pyut spores for the meiosis one and tha tthe famer was cheated. i put 6 for the one tha tased which one has the least CO2. for the catalse onei pu tadd more hyddorgen peroxide and i also has the same answer for the pine one. im not sure what i put fo rhte cuticle thing but i did have guard cells first and endoderm last i cant remeber too sure tho</p>
<p>basically amb3r, we differe on the pie chart thing and the acid rain one</p>
<p>also, i didnt knwo wat the planceta one was so i left it blank. and the cycle one i also had 40 hours. damn i wish there was nice curve</p>
<p>What do you think the curve will be like? I'm thinking of canceling.</p>
<p>Yea the placenta one is nerve impulse.... wat did u guys put for which nutrients were lacking in the soil for the plant question with the four fields which were treated with fertilizers... i put carbon, cuz the graph said on the side- grams of C</p>
<p>honoslty i lot of ppl thot it was hard so im thinking it will be failrly generous. im hoping to get 700 atleast but we'll see.</p>
<p>Like how many wrong for an 800? 4 or 5? or is that too generous?</p>
<p>For nutrients lacking, I just put phosphate because the difference in biomass was greater w/ phosphate fertilizer than with nitrates.</p>
<p>so what was the answer to graph one? the pie chart? or the plot?</p>
<p>i think 4 or five shouldget you an 800. if youre shooting fo rthat..good job. im trying to hit 700.</p>
<p>The answer to the graph one was the line, not the pie chart.
I took Biology E. The actual E part itself was easy, but I was at a loss for some of the genetics.</p>
<p>you guys are saying the placenta IS an endocrine organ or whatever that choice was?? what hormone(s) does it secrete?</p>
<p>Progesterone is one, although it makes others that increase the concentration of blood or something. That's why blood sugar levels are higher during pregnancy. (Learned -that- from my mother, haha)</p>
<p>yay. I guessed the niche.</p>
<p>The biomass didn't make sense to me. What did you guys put? I think I put increasing, but not sure which. My entire logic was that carnivores were probably heavier than herbivores - I have no idea if that's true.</p>
<p>Yeah. I put nerve impulses for the placenta one. It does release progesterone thereby making the endocrine one make sense to me.</p>
<p>For the nitrogen/phosphate question, did you guys put "just nitrogen" as the most limiting? I didn't get it. I mean they all increased, but I guess that was the least, so I put it. </p>
<p>I put sulfuric acid too...Just heard it around too.</p>
<p>What about the circulatory system ones? That was hard. I wish I left more blank. I always feel weird leaving things blank...but it could definitely have been beneficial here..</p>
<p>biomass decreases because higher consumers can't efficiently use all the energy of lower stuff.</p>
<p>So how many do you think we can get off and still make an 800..?</p>
<p>Although I hope it's quite a few, I'm thinking maybe 5 or so =| </p>
<p>I put biomass increases, but I can see how it's wrong now, haha. </p>
<p>Limiting was phosphate - the plant grew more when phosphate was added. Limiting doesn't mean that addition of it limits plant growth, it means that nutrient is the one that the plant needs MOST to grow.</p>
<p>Which one was the sulfuric acid one? I forgot ^^;</p>
<p>The circulatory system one - most CO2 at point 6, and most like a fish's.
At least, that's what I put. Did anyone get anything different?</p>
<p>I'm guessing he meant Sulfur Dioxide. That was the acid rain one.</p>
<p>Does anyone remember any q's?</p>
<p>Ohh, that one. I got that one wrong; don't remember what I put but it wasn't sulfur dioxide!</p>
<p>Let's see.. oh, the biology... genetic tree thing. (Wow, smart. I finish my SATs and forget all my terminology). With the colourblindness. Anyone remember what they answered for those?</p>
<p>it's sex-linked recessive.. I think that was the only tough question in that part. the rest were just testing if you could interpret the pedigree.</p>
<p>Oooh, score; I got it right!</p>
<p>I was initially confused because one of my answers conflicted with the other, but I think that was one of the ones I managed to fix just in time.</p>
<p>I'm trying to think of any others..
I was partially asleep during the Biology exam.</p>
