<p>im pretty sure i chose either I and II or I and III, although i don’t remember which statement was which.</p>
<p>for the one with which organelles are in plants and animals… i said golgi apparatus and mitchondrian… anybody agree/disagree? im pretty sure im right because i remember my bio teacher telling me that plants do BOTH photosynthesis and cell respiration (they just don’t do as much cell respiration), so they would need mitochrondian to do that… right?</p>
<p>yea its right, only organelles that are diff are lysosomes and centrioles</p>
<p>so how is this test scored? Barron’s says you only need a 73/80 to get an 800 but Princeton Review claims 78/80. Though these quesitions were much more complex and abstract than either PR’s or Barron’s</p>
<p>according to the official sat booklet… you can get a 77 and youll get an 800. </p>
<p>does anyone know when the results are going to be out?</p>
<p>Particles don’t ever stop moving across the membrane. The particles continue to move, but equally in both directions maintaining equilibrium…</p>
<p>Im pretty sure the last answer was just I</p>
<p>it was crossing over. and I don’t know about the systolic blood pressure one, I put I and III. I had no idea what blood pressure had to do with mercury, so I let it go.</p>
<p>Did anyone know the one regarding the blastula cell and the frog? It was between “the adult frog cell’s nucleus helps the egg cell develop” and “the blastula’s nucleus provides the genes for the larva development”- I put the former because genes code for traits and are through reproduction/inheritance, not for coding certain functions of the cell at that time.</p>
<p>The dialysis questions on the last part of the Molecular section were weird- I put E, saying all three of them, but I had no idea. </p>
<p>And the one regarding the lavender/pink/blue is not codominance, because it said that for the plant otherthing, not the color.</p>
<p>24th november, comes around 4-5 GMT</p>
<p>codominance is when both express themselves (i.e. when there would be blue and white petals) im pretty sure it was incomplete dominance</p>
<p>That graph on the E section didn’t have the dependent variables increasing at a constant rate, so the graph couldn’t have been “additive”.</p>
<p>Agreed, its not codominance.</p>
<p>But explain how it’s incomplete dominance.</p>
<p>Incomplete dominance = the two traits blend together.</p>
<p>Curly Hair + Straight Hair = Wavy Hair
Red Snapdragon + White Snapdragon = Pink snapdragon</p>
<p>How can Blue flowers + White flowers result in lavender, a mixture of purple and white.</p>
<p>It doesnt make sense.</p>
<p>It’s incomplete dominance. The collegeboard just doesn’t know how to mix colors</p>
<p>btw the albino genotype could only be aa yea?</p>
<p>yes^</p>
<p>what was the chance that a man with recessive phenotype would pass on disease through sperm cells? it was the first question on M</p>
<p>^ i said 100%… i think</p>
<p>Hey, does anyone remember question #86 in the molecular section; and the answer they put. Also, what was the answer to #100? The experiment with the dialysis tubing and beaker of water.</p>
<p>What review book did you guys use?</p>
<p>mainly barrons and princeton, and then did some tests from sparknotes too.</p>
<p>Barrons. </p>
<p>I remember being unsure about the question on the formation of sperm … anyone remember ?</p>
<p>
</p>
<p>Do you remember what the scale was for both the x and y axes?</p>
<p>Just FYI to everyone: the Princeton Review’s most recent Bio study guide DEFINITELY contains at least two or three of today’s test questions in its practice tests. Verbatim. And that fruit-enzyme series was ripped right out of it.</p>
