OCTOBER SAT Subject Test: Biology E/M

Test Preparation SAT Subject Test Preparation
21

<p>micky - i put secondary consumer.</p>

<p>people in my bio class said that the june one was mad easy.</p>

<p>a girl in my school who isn’t the brightest in the class took both june and todays said today’s was easier.</p>

<p>there better be a nice curve or else im screwed lol.</p>

<p>least we get to choose which sat 2 tests to send in now due to new collegeboard’s new policy.</p>

<p>i agree with owner’s responses. for cartilage i think i put c. dont remeber what it said though. for the hemoglobin one, i think i put something bout pressure. there was a question similar in barron’s practice test 2 #34-35. the book said the curve on the right drops oxygen off more easily.</p>

22

<p>a)PR + Barrons = 800 on this test?</p>

<p>b) what was the answer to the question asking for symmetry? the jellyfish n something else?</p>

<p>Buncha stuff that i studied for wasn’t on the test… What happened to all the gland/mitosis questions? d-_-b</p>

23

<p>for the woody stem one i put leaves have more nutrients and less cellulose</p>

<p>for the atom one, i counted the products too.. SO stupid.</p>

<p>what was the answer for the frogs excrete urea, but larvae excrete ammonia one?</p>

24

<p>the symmetry one was sea urchins and jellyfish.
all the others were bilateral symmetry</p>

25

<p>um with 5 wrong, i think u would have a 760 or 750</p>

26

<p>yeah thats right. i just got tripped up on the lab based questions. there were three. did anyone get the answers to the yeast UV one? oh the frog one was because adult frogs can survive outside of the water or something like that. wait didnt the atom one say ALL of the atoms involved in the reaction?</p>

27

<p>dont u just add up the introns and leave the exons out because they are spliced? i put protein matrix</p>

28

<p>i think exons are the ones that r expressed and introns get cut.. i got 350</p>

<p>for the yeast uv one i put DNA.. just a guess though</p>

29

<p>ha I already canceled my score right after I took the Biology E/M</p>

<p>what was with that random grasshopper? i only knew the excretory part</p>

<p>I felt really sick this morning, so I probably had more screw ups than I kno
Does anyone kno what sympatic speciation is? That wasn’t in the Barrons, and I blanked out with what genetic drift was too…</p>

<p>Oh! And that question about the bag filled w starch and glucose? What was that? I put that it wud swell</p>

<p>whatever, upnext NOVEMBER 1st SAT II Biology yay!
who’s with me?</p>

30

<p>sympatric speciation is like when species evolve into other species when theyre still in the same area. and allopatric speciation is when they evolve when they are separated geographically. i didn’t use this for an answer, but idk i could be wrong.</p>

<p>and yeah i put the bag swelled for the starch and glucose question.</p>

31

<p>Here’s what I got:</p>

<p>Grasshopper - legs-B (thorax), excretory-D (head), reproductive-A (abdomen).
I said the plasmid would have 1 gene repeated 8 times (kind of a guess).
Fox is secondary consumer.
Phylogenic tree node is Phylum.
For cartilage I said connective tissue…something…
Gulls in colonies–disease resistence was the “except” answer.
Frogs excrete urea to conserve water.</p>

32

<p>got 5 wrong so far.. :frowning:
i looked up the grasshopper excretion on google.. it said it’s in the hindgut, so i think it’s in the abdomen? i think that one was A then</p>

33

<p>[SparkNotes:</a> SAT Subject Test: Biology: Scoring the SAT II Biology](<a href=“http://www.sparknotes.com/testprep/books/sat2/biology/chapter2section6.rhtml]SparkNotes:”>http://www.sparknotes.com/testprep/books/sat2/biology/chapter2section6.rhtml) for the regular curves, I guess.</p>

<p>I thought that the test was fairly easy, and I only had to guess (ie narrowed it down to 2-3 answers) for 5 of them or so. Hopefully the curve is somewhat generous and I still manage to get an 800. ;D</p>

<p>I completely messed up on the intron/exon one lol, so -1 there…</p>

34

<p>I haven’t had Biology in three years, so I’m certainly not an authority. I got the grasshopper confused with another insect…</p>

<p>Three wrong so far…</p>

35

<p>what about the one about the graph of light exposure and co2 production.. was it the slope? and were they directly proportional?</p>

36

<p>How did you prepare for the test, Moddrets? Which books?</p>

37

<ol>
<li>grasshopper: legs attached to thorax (b), excretion at (a), i left the reproduction one blank, but i think it’s (a) too. here’s a diagram of the anatomy of a grasshopper: <a href=“http://universe-review.ca/I10-82-grasshopper.jpg[/url]”>http://universe-review.ca/I10-82-grasshopper.jpg&lt;/a&gt;&lt;/li&gt;
<li># of atoms involved in photosynthesis reaction: 36 (don’t remember which letter)
2a. @ava.k: yeah i said slope & directly proportional</li>
<li>which type of blood cell carries oxygen? which type of blood cell’s primary purpose is for clotting?</li>
<li>why do tadpoles excrete ammonia and frogs urea?</li>
<li>which animal has an open circulatory system? i was almost sure it was earthworm, but it was (b) (which i forgot what it was), and definitely not fish/reptile (?), bird, or human (all chordates).</li>
<li>i feel the curve is a lot more generous than sparknotes makes it out to be… isn’t it usually 800 for 4-5 wrong? my friend took it in may, left 5 blank, got an unknown # wrong, and got 780. so far i’ve left 2 blank and gotten 2-3 wrong…</li>
</ol>

38

<p>I think erythrocytes carry oxygen, platelets clot.
Tadpoles excrete ammonia because they live in water…?
Earthworms are closed circulation - insects are open.</p>

39

<p>I thought the test was mostly easy, except I made some dumb errors…</p>

<p>BTW, I took the ecology test.</p>

<p>**There was a question about protease in the lung, smoking, and smoking causing the destruction of a natural protease inhibitor. The answer is pneumonia. **</p>

<p>I can’t believe I put Emphysema!!!</p>

<p>Also, another question I got wrong was the one about cartilage, which was the answer containing “fibrous matrix”</p>

<p>I put osteocytes (cells which form bone). How stupid!!!</p>

<p>Wink is right about what he said: </p>

<p>**Grasshopper - legs-B (thorax), excretory-D (head), reproductive-A (abdomen).</p>

<p>Phylogenic tree node #1 is Phylum.</p>

<p>Frogs excrete urea to conserve water. (ammonia is far more toxic and requires much more water to excrete–>source is cliff’s ap bio book) </p>

<p>The red blood cell carries oxygen and also lacks the nuclei.
Platelets form clots.**</p>

<p>Owner is right about what he said:</p>

<p>**water goes up because of transpiration pull</p>

<p>mendel used dihybrid cross to prove law of segregation</p>

<p>some clarifications:</p>

<p>there were 36 atoms involved in the reaction of photosynthesis (remember-only reactants are initially involved in the reaction 6h20 and 6co2)</p>

<p>according to the one-gene-one-polypeptide rule, the plasmid should code for 8 different polypeptide or proteins. </p>

<p>different reproduction success rates are caused by natural selection (remember this example: hawks naturally select white mice over black ones (phenotype) in areas with dark surroundings such as a coal field)</p>

<p>most genes in a human being aren’t unique only to the human beings; many other animals have these same genes</p>

<p>the inversion mutation is like this <em>familiar</em> one ATTGAC–>TTAGAC</p>

<p>fetal hemoglobin absorbs more oxygen than regular hemoglobin at lower pressures–this should’ve been obvious when you read the graph **</p>

<p>Please ask me if you need anything else clarified!</p>

<p>OMG! Thank goodness i wasnt the only one that think this test was freaking hard. I had half the test done and 20 minutes left!!! Most of the stuff i’ve learn (which i memorize alot) wasn’t even on this test like the arthopod thing and some weird charts and the lab questions were even more confusing!!!</p>
