November 2008 SAT Subject Test: Biology

<p>Questions were about those light spectrum. Snake follows <strong><em>. Plants dont absorb </em></strong><strong>. Insects use _</strong>__ to predict the place were pollon falls. Highest that human can see. </p>

<p>a) UV light
b) violet
c) green
d) infrad
e) microwaves</p>

<p>I put d, c, e, b</p>

<p>I put d,c,a,c.</p>

<p>im pretty sure the AaBBCc was 4
being ABC, ABc, aBC, aBc
there are no other combintions</p>

<p>Here are a few memorable questions on the test that I struggled with</p>

<p>What was the placenta one (Which of the following are not a use for a placenta)
I think i placed "An endocrine system at birth of child"</p>

<p>What is the way higher plants spread their genetic code
(It was either like spores or endospores or something)</p>

<p>Anyone figure out how the amboas move or whatever?</p>

<p>What is it called when a single celled organism moves towards food?
Learning?</p>

<p>What type of lung system did it represent?
Snake/Amphibian or something?</p>

<p>What does not have a bony skeletal system?
Sharks?</p>

<p>What was the answer to the first bio M problem about cysoine C?
The amino acids sequence?</p>

<p>Also why is there a small portion of small red oaks?
I put animals cuz it said there was no human intervention which made me not want to put hybridization</p>

<p>Another one was what was the key part of an oxid-reduction reaction?
I went chemistry and ignored the biology answers and said it was the transfer of an election from an electron donor to an electron receiver</p>

<p>What is required for gas exchange in ALL living organisms?
I wanted to say gills/lungs but obviously not all living organisms have that so i guessed and said a wet/moist membrane</p>

<p>u were right</p>

<p>i put endocrine for the placenta one too</p>

<p>i put spore for the higher plants question</p>

<p>i put E for that question about the peremecium moving to its food ....idr wut it was....but i think i got it wrong....some people thought it was taxis......or something....idk wut that is....lmao</p>

<p>sharks don't have a bony skeleton</p>

<p>i put amino acid sequance for the first M problem too.....idk tho...i didn't get it either</p>

<p>i put because of the seeds of a larger one for the oak question because it was highly unlikely that like animalls brought 14 seeds to the area......nd.....yeh idk...now that i think about it....it might be the animal thing because it was after like 25 years....</p>

<p>i put wet moist membrane for that one about the gass exchange too</p>

<p>xorogrim,I looked a few up</p>

<p>1) The placenta does act as a temporary endocrine organ, but does NOT send nerve impulses from the mother to the child</p>

<p>2)Directional response to a stimulus is taxis(amoeba question)</p>

<p>3) It was a fish circulatory system (two chambered heart, gill-like gas exchange areas)</p>

<p>4)Sharks do NOT have a bony skeleton</p>

<p>4) I believe gas exchange requires a moist membrane</p>

<p>5) I put that they were carried in by animals too</p>

<p>6) I took eco, but I know that cytochrome-c has to do with amino acid sequence and is a key sign when determining evolutionary similarities</p>

<p>For the placenta one I put nerve impulses because doesn't the placenta release progesterone?</p>

<p>is food considered a stimulus?......because it is not a type of stimulus in my book......unless it goes under chemotaxis</p>

<p>A taxis (plural taxes, pronounced /ˈtæksiːz/) is an innate behavioural response by an organism to a directional stimulus. A taxis differs from a tropism (turning response, often growth towards or away from a stimulus) in that the organism has motility and demonstrates guided movement towards or away from the stimulus.</p>

<p>I got that from a website that sounds like "like my pedia" haha</p>

<p>wow i am confident that i BOMBED that test...ahhhhhhhhhhhh</p>

<p>Well as long as you're not a senior (like me) you get score choice. If not, you shal be condemned to the life of a truck driver or feces scooper(that's what happens to ALL people who don't get 2400 SAT and 800 on SAT II BIO) haha
cheer up kid =)</p>

<p>The plant one that said something like, "Which of these nutrients stunts plants growth"</p>

<p>I placed nitrogen because it raised it the least?</p>

<p>i said oxygen...just because. HA...is that wrong bc it was the control??</p>

<p>and unfortunately, i AM a senior. im going to have good scores in everything but this one test...and therefore will probably end up going to community college hahaha ahhhhhh im so disappointed bc i guessed on so many that i should have left blank...</p>

<p>i didnt think it was oxygen because it was like NO2- PO3- etc. so they contained oxygen (the fertilizers)</p>

<p>Nitrogen limits plant growth the most out of all of the choices</p>

<p>What was the answer to the "what animal are rats closest too".. I put squirrels?</p>

<p>same i put squirrels</p>

<p>Is a -6 approximately an 800?</p>

<p>Unfortunately I believe the curve for biology is harsher. Probably -4 = 800</p>

<p>for the placenta i put the convey co2 and o2 or whatever form the fetus to the mother
i didn think the fetus would transfer gases to the mother</p>
