<p>Something I found that might settle it.</p>
<p>so for the third one…do we think the answer is “start mechanisms to raise Calcium?”</p>
<p>^ Well that’s what I put.</p>
<p>Can somebody PLEASE answer if they took molecular and remember the Mrna and TAT graph section questions? Here are the answers i remember getting: </p>
<p>first question is Translation–(or was it transcription?)</p>
<p>second question was like…the reason for the lagging in the graph–>Answer is that the TAT needs to time to assemble the Mrna first</p>
<p>next question–>what was proven in experiment II …i put answer choice with I and III which said that TAT was a protein and that proteins that made Mrna were present before the protein inhibitor came in</p>
<p>I don’t remember the last question–>but my answer said "Neither Mrna or TAT would be produced.</p>
<p>Um. They huntington’s should be 50% definitely. A normal punnett square would have sufficed. Collegeboard tends to make you think extra hard and make you delusional :P</p>
<p>For the plant labs. First one was response to Gravitropism. Second to thigmo. third to light. and they all are caused by plant hormones.</p>
<p>all arthropods have chitinous exoskeleton.</p>
<p>PTH is inversely correlated with calcium. lower calcium=higher pth. if you remove the parathyroid, the pth goes down. the question were you had 50mg of calcium, the body balances it so it increases the calcium.</p>
<p>Plants need nitrogen, thus in nitrogen-less soil they need to consume protein.</p>
<p>Cows-egret = commensalism</p>
<p>Tomato=virus</p>
<p>Photosynthesis lab- all 6 carbon end up in glucose. plants can use both o18 and o. there was one question i wasnt sure of, and that was “what does experiment I show.” I picked the O in carbon ended up in H2O. It h2o wasnt leftover, cuz it would have to radioactive. All the O were actually used up (balance the equation, 12h2O=12O, 6o2= 12O).</p>
<p>Ok for the tat and mRna one. glucocorticoid didnt cause identical response in tat and the mrna because the lines were diff. the answer was probably the mra increases. If you introduce a protein inhibitor, it blocks translation. However mrna is still made, which means that the enzyme that makes the mrna was already in the nucleus. If you block mrna synthesis however, both would not increase, because w/o the mrna there would be no protein. </p>
<p>For the last lab in M. What could be drawn from the graph? I was gonna put bacterial resistance, but the graph didnt really say that. So i put the bac. had declined at day 8.</p>
<p>Lysosomes break down fat. </p>
<p>Grassland was definitely the answer. I mean, we dont just cut down rainforest for food right?? o.o</p>
<p>mendel= quantitative observation</p>
<p>fermentation, cell resp = atp production</p>
<p>um and the gymnosperm/angiosperm one, wasnt it asking how they were diff? or it had an “except”. think i put cones.</p>
<p>Has anyone notice, but like 75% of these questions were actually on past released tests o.o and some model tests.</p>
<p>I took biology-E and don’t remember the tay sachs Question…Was it on M?</p>
<p>yea I think it was. sorry for not including that.</p>
<p>l4dygaga-- the gymnosperm/angiosperm definitely had an EXCEPT so the answer was cones</p>
<p>Yeah, I think it was cones</p>
<p>The first plant experiment wasn’t gravitropism, it was light, then touch, and then something else?..Somebody please confirm this.</p>
<p>l4dygaga–“For the plant labs. First one was response to Gravitropism. Second to thigmo. third to light. and they all are caused by plant hormones.”</p>
<p>i dont remember this at alllll…was this on M? Can you remind me what you are talkin about?</p>
<p>
Could you remind me of the third plant one?
I agree with all those. What did you put for the second one which asks what happens to the level of calcium if the thyroid gland is removed?</p>
<p>
I think basically the point you were supposed to obtain was that translation is blocked. They didn’t seem too complex too me.</p>
<p>
It actually increased after day 8. So that one doesn’t work. I said that some bacteria were resistant since not all of them died out.</p>
<p>All you have for the huntingtons question is that the father has it and the mother has no history. You have no history of the father’s family. This is NOT a sampling of an entire population, it’s one person. Since you have no knowledge outside the fact that he has it, there is a 50% chance he is heterozygous and a 50% chance he is homozygous.</p>
<p>Was the hormone in TAT MRNA a protein?</p>
<p>I said no because I thought it was a steroid based hormone since it effects which gene is transcribed…</p>
<p>Blacklaw, it was gravitropism. All the plants crew downwards and the petri dish itself is set down on its side. There were no light available so it couldn’t have been phototropism</p>
<p>^^^Yea I was with you before. But everywhere you look online they say the homozgous allele is REALLY rare. And look at the first post on this page. That came from a college website. So I think 50% is right after all.</p>
<p>Barricade, TAT mRNA was a protein I think since it affected translation not transcription.</p>
<p>I basically agree with l4dygaga’s post. That calcium graph threw me off! I think I got those wrong, but in all honesty I completely forgot what I answered, haha. But the Huntington’s one was definitely 50% :-D</p>
<p>I suppose we can argue back and forth as much as we want, but in the end, we won’t know till scores come out.</p>
<p>In that note, I’m done with these threads-no sense getting preoccupied.</p>
<p>for a genetics question, was it tall and potato-leaved dominate?
and for the last M question, i put that some bacteria in the urine were already resistant, but i wasn’t sure about it.</p>
