OFFICIAL SAT II BIO June 2..

<p>What was the benefit of a four-chambered heart?</p>

<p>I think the answer was "separate circulation to lungs". The answer you should have been looking for was separation of oxygen-rich and oxygen-poor blood, so that answer was the best.</p>

<p>What was with the freaking bird question? None of the answers made sense. I lol'd when they said to use a virus to slaughter the birds.</p>

<p>UUUUUUUH wait i don't remember a question about a four-chambered heart... was that e?</p>

<p>they were asking wat was the advantage of a four chambered heart, and it was that it could circulate to the lungs</p>

<p>ok i actually don't remember seeing this problem at all... and i know i saw all the questions for M...</p>

<p>it may have been in E-section, if i remember correctly</p>

<p>MechaSnoopy, that's what I got for that question.</p>

<p>Yeah, im pretty sure that was part of the E secion</p>

<p>Got most of these right!
Boiling leaves -- remove chlorophyll
I remember putting something about plasmodesmata
Photosynthesis and respirtaion for carbon cycle</p>

<p>TUNIT -- are you talking about the one that had hydrolizing glucagon or something and the choices were something like RNA, fats, proteins, amino acids, and glycogen?!?! :D</p>

<p>I effed up the karyotype and i think it was the plasma membrane instead of the golgies</p>

<p>what was the actual question concerning the attachment of proteins to carbohydrates.
transmembrane glycoproteins are attached to secretory proteins in the golgi apparatus. Then the glycoprotein, which is in the wall of a vescile, moves to the plasmamembrane. and when the vesicle fuses to the membrane, the glycoprotein becomes part of the membrane.</p>

<p>was the question asking where glycoproteins are located, or where carbohydrates are joined with proteins?</p>

<p>any1 remember if the answer to that one is fibrinogen or platelets...they both make clots...</p>

<p>platelets b/c they are cell fragments.
what about the dialysis one?</p>

<p>i skipped the dialysis one :(</p>

<p>Dialysis, is the metabolic wastes.</p>

<p>making sure --- the one on E with the branch being 4 feet and then it growing 2 feet was ... 6 feet right? the following question was root and shoot meristems?</p>

<p>the very last core question (for me) was about the experiment with temperature effects on the reaction and enzymes and it asked between 25-35 degrees. was it I and II only?</p>

<p>the one with which wasnt a membrane bound organelle or w/e was chromosome. im almost positive.</p>

<p>on the part witht he bird being introduced int he 1900s and the map or w/e, wasnt the first questions (with keeping the birds biological safety or population size) was study the ecological habits or something (E)?</p>

<p>i think the branch one was 4 feet, because only the top of the tree and the roots grob...but the stump doesnt move after it is formed</p>

<br>


<br>

<p>also, there was a question about "which of the following would least affect the carrying capacity or population density or something"</p>

<p>was it parasites? everything else seemed important and parasites dont actually kill organisms.</p>

<p>Decomposers. DANG IT I got all the really stupid one's wrong...ie Deadly Clover, Tree Growth, Branch Height, Trisomy, Mollusc Shell, Carbon Cycle...</p>

<p>decomposers actually affect that though. when they break down dead matter, they put more things back into the biogeochemical cycle, increasing potential to carry more organisms in the population. why is parasitism important for it?</p>

<p>yeah but decomposer have the LEAST direct effect cause organisms cant know where the decomposer are and it does not effect the density....</p>
