<p>davidskim1234 - The answer choice said food CHAIN (While the question said food web). Because of this, I think the BEST answer was that herbivores get more energy than carnivores, but it's still true that you lose energy (by a factor of 10, I believe) the farther up you go.</p>
<p>what was the question again?</p>
<p>i do'nt think herbavores get more energy than carnivores. i think they need probably the same amount of energy to stay alive- it's just that carnivores need to eat a lot more herbavores since there is less energy in an herbavore than in a plant. that's why there are a lot less carnivores than herbavores.. carnivores need to eat a lot of other animals to get the same amount of energy.</p>
<p>did anyone get that question in the M section</p>
<p>It was one of the last ones. It was like the bag where only the sugar got into the beaker and it asked you what you could conclude from the experiment.</p>
<p>was it because only the sugar was soluble in water. That was the only reasonable answer besides molecules are separated by size in semi-permeable membranes...but that couldn't be it because the diagram had nothing on size...</p>
<p>I think the answer to that question was the size of the molecules, because the other substances (lipids, etc) are larger than sugar and therefore couldn't cross the semi-permeable membrane.</p>
<p>Also, (i think this was the last question on the test) and one of those I, II, III type questions. i forget what I was, but i'm pretty sure I was wrong. II said something like towards the end of the experiment the sugar stopped moving across the membrane, and III said that the solutions inside/outside were isotonic. Number II was the only correct choice right?</p>
<p>I answered size as well on that last one.</p>
<p>pike - Bah, I screwed up on that one. I don't know why I put isotonic, now that I think about it...:(</p>
<p>How do you know that it stopped moving across the membrane. Theres nothing to indicate that. One trick that CB uses is making you chose implied information that really isn't always true.</p>
<p>There was no none of the above answer choice..and i'm pretty sure number I was wrong. I dont remember what it was, so if someone does please post it. II seems like the best choice</p>
<p>I answered II and III for that one as I figured that the water concentration would be equal in both due to diffusion (=> solutions are isotonic).</p>
<p>^ Isotonic means the solute concentration in and outside of the bag is equal.</p>
<p>I did choose the one that says sugar doesn't move out by the end of the 24 hours anymore, because I thought of it this way: Once both solutions are isotonic, then if sugar moved around it would cause an imbalance in the solutions.</p>
<p>What did you guys get for the one that asks:
Which of the following is not an example of homeostasis maintenance? </p>
<p>I chose secondary sex characteristics, but I kept thinking in my mind that it was wrong :( I just couldn't cross out any of the others.</p>
<p>no II was wrong because you don't know that the sugar stopped moving...
there is an undefined amount of sugar</p>
<p>and the time period was 24 hours</p>
<p>there is no certainty that the sugar all diffused into the bag</p>
<p>and its not III either...I think i put I</p>
<p>what did you guys put for the question with the 2 pairs of the chromosomes of the parent cells and 1 pair of chromosomes for the gamete</p>
<p>I put crossing over because the chromosomes were different</p>
<p>Yeah, it was crossing over. It asked for the GENE arrangement, which is changed by crossing over. If it asked for CHROMOSOME arrangement, the answer would be independent assortment. But that wasn't an option anyway :P<br>
Crossing over is right :)</p>
<p>i totally guessed on a few questions</p>
<p>OK I think that I missed some of the "easiest" questions on the test.</p>
<ol>
<li><p>Is a turtle a reptile? Or was it an eel?</p></li>
<li><p>On the E section, flowers that "are not brightly colored and are not scented are most likely pollinated by what?" The choices were bird, butterfly, wind, fly, or bees. I put wind...flies don't pollinate plants, do they? And don't bees and butterflies need the bright color and what not to be attracted to it?</p></li>
<li><p>What part of the flower does the peach come from? I put ovary...but I really had no idea. </p></li>
<li><p>Which part of a plant has a cuticle? I knew it was the leaf, so I put epidermis. Was it stomata? Or something else?</p></li>
<li><p>For the production of sperm...was it the increase in lutenizing hormone?</p></li>
<li><p>There was one question that asked about proteins and enzymes and where they were secreted in humans with the choices being mouth, stomach, small intestine, and various combinations of the three. What did ya'll put? </p></li>
</ol>
<p>There are so many others that I was unsure about. I spent way too much time studying for Math II and WAY TOO LITTLE time studying for Bio...pretty much everything that I had down really well from my AP Bio class was not tested at all. Askjflkdjafds!</p>
<ol>
<li>turtle</li>
<li>wind</li>
<li>ovary</li>
<li>epidermis</li>
<li>forgot what i put</li>
<li>small intestine ONLY</li>
</ol>
<p>I was disappointed that there were almost no human anatomy questions, as I studied that pretty extensively. But overall, I think I did alright.</p>
<p>I was so glad that there were no heart questions dealing with the transport of oxygen through the heart and stuff. I get the names of everything confused with that. Also, I was shocked but happy that no questions about the structures of the brain and their functions were on there :)</p>
<p>Anybody remember any more questions? </p>
<p>Maybe discuss some the E questions? That first question on E was killer, I ended up skipping it.</p>
