<p>ok good :)</p>
<p>I put mouth and small intestine too.</p>
<p>As for the mendel one, I thought C hit most accurately. Sexual reproduction is too broad a term-and remember, Mendel could not explain the function of genes or the process of meiosis.</p>
<p>^I put moth and small intestine as well; I remembered the mouth part from prep. And then it made more sense that the small intestine would have the enzyme rather than the esophogus (which was the other answer paired with mouth).</p>
<p>for the human food one i put grasslands. If you think about it, the majority of human caloric intake comes from carbohydrates in grassland plants such as wheat, corn etc. And most of the meat that we eat has been fed products of grasslands, so it only makes sense...</p>
<p>@hopeful5: You're probably right.</p>
<p>@eleven_hobbit, whatiscollege, isabella: it's certainly mouth and small intestine... the amylase enzyme is secreted by salivary glands and by intestinal cells if i remember correctly but the answer is mouth& s.intestine 100%...</p>
<p>hey guys, quick question</p>
<p>for the birds mating question (first page), what was the answer? one of those photo- things. i forget what the answer choices even were haha something like:</p>
<p>A) photoperiodism
B) phototropism
C) photosynthesis
D) phototaxis
E) and one more</p>
<p>photoperiodism</p>
<p>the "and one more" is photorespiration.</p>
<p>Anyway I got photoperiodism for the birds too.</p>
<p>does anybody know what the raw score conversion is for 8 wrong?</p>
<p>(it'd be like 70 out of 80)</p>
<p>My real SAT II's book says 780 for E and 770 for M. The curve will vary a bit from test to test though.</p>
<p>photorespiration was not used, right?</p>
<p>not that i recall no</p>
<p>What was the right answer for the tapeworm one? (for those who took E)</p>
<p>For the starch one, I thought it was mouth & esophagus because disaccharides are broken down in the small intestine, whereas polysaccharides (starch, glycogen) are broken down into smaller polysaccharides in the mouth and esophagus.</p>
<p>That actually reminds me of that one question on (I think) the general section about what angiosperms have that most vertebrates don't--was that asexual reproduction or starch storage? I put starch storage because don't most vertebrates store energy as fat? And isn't hermaphroditism (like in angiosperms) NOT a form of asexual reproduction (there are still gametes)?</p>
<p>The consensus seems to be 2 mutualism and 2 photoperiodism for one of the first questions, but wasn't the example with the cow commensalism? One organisms was eating the stuff that fell of the cow, but the cow wasn't benefitting.</p>
<p>Yes, that one was commensalism, but there were another two that were both mutualism (I think).</p>
<p>no digestion occurs in the esophagus. It was mouth/small intest</p>
<p>@Vfrizz:Yeah but those are different exercises. The one you are talking about is part of the '2mutualism"</p>
<p>and there was another bundle only with photo-stuff</p>
<p>Actually, I just checked the Campbell Biology book and it says that salivary amylase, which breaks down starch, is secreted into the oral cavity, esophagus, and pharynx. So I guess that makes it mouth and esophagus.</p>
