<p>I put sensory as well!!</p>

<p>@raza68: yea, animals and plants diverge.</p>

<p>I just remember the question asking about comparison between chloroplast and mitochondria. It is I and II rite??</p>

<p>thats what I put!</p>

<p>i believe the roman numeral one was II only. but i wasnt sure</p>

<p>i think i had I and II as well, then looked closer at I and saw that it said that the HOX gene was not expressed in plants and bacteria, while the graph said the gene was absent altogether.</p>

<p>ahh for the higher temp one why isn’t it C4 photosynthesis?</p>

<p>I put sensory yay yay!!</p>

<p>, thats what I did, I put only one answer for the 3rd to last one… And for the cholorpalst one in the beginning, I am pretty sure I put 1 and 2</p>

<p>so is it sensory or motor? and C4 photosynthesis does not promote better functioning at different temps but rather at higher levels of O2 when photorespiration would occur in C3 plants</p>

<p>@hesterpryne Uh I don’t think so. The water temp only affected the enzymes really. It’s less likely to have more DO since its warm…wait a moment</p>

<p>Did it say it THEN increased it or that they redid the lab. IF its THEN THEY INCREASED IT 5c it could be the water DO going away from the water and into the bubble. A 5 degree change could be it, but IT WAS THE SAME ALL ACROSS. (Wait did it say that it was the same increase or just that it increased) If it the same increase or the same percntage it could very well be having to do with DO. The enzymes only work really based on amount of light. </p>

<p>So basically </p>

<p>Did the question say</p>

<ol>
<li>They then redid the lab and increased it 5 degress and the oxygen volume increased
or </li>
<li>They then redid the lab and increased water temp 5 degrees and the oxygen volume increased in all (same percent increase or something like that)
or </li>
<li>They then increased the temp 5degrees and found more oxygen.</li>
</ol>

<p>so is it sensory or muscle? Have we come to a conclusion. Any one else taking the AP Test monday?</p>

<p>was it ever agreed upon for as to which pigment would have the greatest effect on the plants? green?
also, for the two populations living between the low-tide line and the high-tide line, did the correct answer have to do with the density of their nests or substrates?</p>

<p>Hester and other YAY dude…its not sensory. If it was I’d be happy though.</p>

<p>@141421356- i think 3?
@hheellpp- I put green. And I also put substrate</p>

<p>raza68 im taking it. im a soph and im freaking out… its my first AP test and im pretty nervous</p>

<p>green, motor, substrates
and yes im taking the test on monday</p>

<p>It said that they redid the lab and increased the water temp 5 degrees and the rate of oxygen production increased in all. I believe its sensory 90% sure (i searched it up). and yes it was the substrate</p>

<p>Scuba was that in M? DO you remember at least what one of the choices was for the mitochondria thing?</p>

<p>And as for the conclusions. </p>

<p>I put green because thats chlorophyll a and A is the biggest producer. If it turned green then only the other cartenoids would have to pick the slack , but they can’t</p>

<p>And I think its motor. Even though I put sensory. Hmm. I just read an abstract and it said. If so, :frowning:

To characterise the intrinsic motor neurones of the gall bladder and identify their roles using pharmacological techniques. …</p>

<p>@141…: Yeah that’s the confusing part and I didnt see it while I was taking the test. I merely thought that the temp increases and affects the enzymes. Well ="= I will ask my teacher then
@raza: Hey im with you. I did so poorly in this test but I feel kinda more ready for Ap dont know why :)</p>

<p>haha, i am not too worried. I have already taken some aps, so im kinda used to them. Just remember to go over the princeton review (or anyother review book). If u got an A in the class, then u are almost gauranteed to do good.</p>
