<p>lipids can be polymers if its a triglyceride, steroid, or phospholipid bilayer</p>
<p>i'm pretty sure it is proteins, because proteins can only be polymers, since they are made of amino acids.</p>
<p>Protiens= polymers </p>
<p>theres no argument for that...</p>
<p>Protiens are AlWAYs polymers while lipids can be polymers, but are not always</p>
<p>yeah, i know that question is a little weird, I was thinking lipids too but it has to be protiens</p>
<p>I'm pretty sure energy being lost at each level (90%) is the more correct answer ...it encompasses the answer choice saying that herbivores gain more energy than the other subsequent trophic levels ... </p>
<p>it makes sense...</p>
<p>yea i put that as well</p>
<p>okay i'm confused about the breathing of reptiles and amphibians.</p>
<p>things online say BOTH have lungs? *** mate?</p>
<p>OK, I did the M test.
The energy cycle: definitely loses lots of energy as it goes from trophic level to trophic level
The first question was definitely skin, because the frog is an amphibian
What about the energy for phosphorylation one? I put oxidizing glucose but I'm worried because technically its NADH and FADH2</p>
<p>for the flies problem, what were the choices?</p>
<p>heart rate question: i think it's alcohol b/c in high doses, it's a depressant</p>
<p>food chain: isn't it also true that herbivores get more energy than carnivores? and i guess i thought that "energy lost" meant actually just "lost", and that didn't include the respiration energy used by the original trophic level</p>
<p>flies: i think it's hotspot b/c that would only deal w/ temp., not the volcano issue b/c that's already addressed in choice A</p>
<p>soil: wouldn't it be lichens b/c it's a pioneer org? b/c if the question wasn't testing that concept, could we actually decide that it would be shrubs or herbs, etc.?</p>
<p>i also think its alcohol</p>

Increases blood flow to the skin - This causes a person to sweat and look flushed. The sweating causes body heat to be lost, and the person's body temperature may actually fall below normal.

second result</p>
<p>for the flies problem, what were the choices????</p>
<p>for the flies problem, what were the choices?</p>
<p>good stuff, wut bout the other ones? damn i'm really kicking myself 4 changing the seed dispersal one</p>
<p>wut are the chances of a curve like may's (-6=800)?</p>
<p>no offense guys, but we've answered nearly all of the "difficult" questions already... you can probably find the answer faster by reading as opposed to just posting</p>
<p>nobody's answering my question :( for the flies problem, what were the choices?</p>
<p>i'm thinking a curve that big is unlikely, but definitely possible. anyone know how exactly it's computed?</p>
<p>hey guys i just finished reading over this entire thread wheww XP
based on all of your answers i feel that i missed around..say 5.. so im not disappointed -_- and omitted 3. im not sure about this whole scoring thing, first time taking any sat subject test.. can you estimate my score?? thanks so much if you can!</p>
<br>
<p>700, likely.</p>
<br>
<p>I'm pretty sure someone asked this one already, but what's the answer to the energy for phosphorylation of ATP?</p>
<p>yah.
im SURE i got above a 700.
so far, i've lost 5 raw points.
sobs.
75 raw would be...</p>
<p>800 on Barron's Biology E/ 790 on Barron's Biology M
or
770 on PR's Biology.</p>
