November 2009 - Biology (E/M)

<p>damn… seems like i got like 7-8 wrong and 1 omit, thatd be around 750 ? Using the collegeboard official book 7 mistakes and a omit for molecular puts me at 760 and then 8 or 9 mistakes plus an omit puts me at 750. I just hope I get that, do the curves tend to change alot?</p>

<p>What were the answers to the following questions:
Which reduces heart rate? climbing, alcohol, aphetamines, drinking coffee, and some other choice
What was the answer to the frog and snake question? (it was the very 1st question)
Does anyone remember what was on the x and y axes for the question with the constant line?</p>

<p>frog and snake= something about breathing through skin
@fadh2- im just saying rna has more than 1 phosphate when they specified that the molecule they were looking for specified for just 1</p>

<p>ok for those who took the m section what were the answers to the retrovirus questions? and also what was the annswer to the question about hairs on a plant? was it for protection, seed dispersion…???</p>

<p>alsoo then what is the general consensus? RNA or nucleotide for the answer? anddd i thought it was that hawaii was on a hotspot but im not quite sure…</p>

<p>I took Biology-M. I thought the whole test was really easy, or maybe Barron’s just overprepped me.</p>

<p>i think its nucleotide for sure it is on princeton question one of the exact question and the answer is nucleotide so … its not RNA RNA is a polymer and nucleotide is a single thing which is what question described also i put mantle becasue more plants can lead to diverse speciation due to more things avaialbe and different conditions… mantle has nothign to do with speciation …</p>

<p>p.s LOOK AT 21. PRINCETON TEST #2 it says nucleotide " if one ribose molecule were bound to one adenine molecule and one phosphate molecule, we would have a "</p>

<p>the answer is B necleotide</p>

<p>does SAT II BIO ever test you on the history? like which biologist did this to disprove this theory.</p>

<p>potentenum - not really , i’ve taken a lot of tests and i’ve never seen them test history. i’d be vaguely familiar with the big names though.</p>

<p>wait i dont remember the mantle one being an answer… u sureee its not the hotspot haha i really hope it was</p>

<p>yea yea sorry hot spot i think is the answer lol</p>

<p>hotspot is probably not the answer, as that’s a place of BIODIVERSITY…aka more than one species of a genus, in this case the Drisophila mosquitoes.
The mantle answer is probably right, even though I put the plants answer(darn)</p>

<p>What’s 3 or 4 wrong considered on the test?
780 maybe?</p>

<p>1 omit + 8-9 WRONG is a 750 according to the Collegeboard book? Are you sure you didn’t forget to take off points foe wrong answers?</p>

<p>I’m not insulting you or anything, but if that’s the case, then I should be find too, cause I also omitted on and probably got 8-9 wrong</p>

<p>no mantles are places of diversity as well</p>

<p>i think that frog answer was breathing through the skin too. btw, i think its RNA, check the princeton tests. they ask a similar question, and if u flip back to the answers, theyll tell you why nucleotide is a trick option.
what did you guys get for that amphetamines, alcohol, etc question?</p>

<p>I searched the internet and found out that a phenomena called “leukocyte Plugging” can cause the bloackage of capillaries, and I choose the sample which had excessive amount of white blood cells. For the herbivore vs energy lost question I put the former, but guess I may be wrong…Only that I remember it asked about what is true in EACH step of the tropical level, and I heard that 1/3 of the energy produced by photosynthesis is consumed by respiration, and the rest is used by the plant for its growth. In this part not MOST energy is lost.I know it’s kinda silly, but please don’t laugh:(</p>

<p>Lalune, I’m sorry to say but your wrong on both points</p>

<ol>
<li><p>There is a scarce amount of literature available pertaining to leukocyte plugging whereas scientists know for a fact that people diagnosed with sickle cell anemia have troubling breathing in certain environments because their hemoglobin clumps together inside the capillary walls. Thus, oxygen cannot reach vital organs and they feel light-headed.</p></li>
<li><p>The rule of 10 says that about 10% of energy is lost between trophic levels</p></li>
</ol>

<p>Anyway, thanks for your answer~I just already counted them in my wrong ones after the test@_@</p>

<p>^^^^@LaLune
Sorry if it came off kinda mean</p>
