<p>birds sexually reproduce, the female harbors the male gonads</p>
<p>yeah but that's fertilization isn't it?
hmmm - im brain dead</p>
<p>i was thinking more of a sense that the birds lay eggs</p>

<p>all about bird beaks. read beneath the picture</p>
<p>What was the one with plants evolving from water based to land based? I chose cuticle because it prevents the loss of water..but barrons AP prep says that they evolved cell walls to make the plants stay up...but dont all plants have cell walls?</p>
<p>also , for the urine graph, did anyone put 1 that the bacteria was mostly excreted</p>
<p>yeah i chose the epidermis</p>
<p>for the lipid did u put all three (fat, membrane...and i forgot the third)
for hydrophobic - they arein the middle</p>
<p>^ was that from M? I took E</p>
<p>i chose cuticle also, i thought they had cell walls before too, but if barrons says thats it, then theres a good chance it is</p>
<p>Well, actually Barrons says that both of them were adaptations.. W<em>T</em>F?.. plus, I'm fairly sure ALL plants DO have a cell wall..</p>
<p>cuticle... huh... was this question in the 1-60 part or like... in E or something? i don't remember that answer choice...</p>
<p>f' barrons thats messed up... now that i think of it how would a cuticle help make that transition... cuz its there for protection</p>
<p>and for the flat worm question it was a I,II,II question and one of them was lacks a digestive system. I put E, I,II,III</p>
<p>and does platyhelminthes have a psuedocoelom/no coelom, or coelom</p>
<p>ye um barrons kind of screwed me. It says specifically in the barrons passage that fermentation does not yeild ATP, but i guess that's entirely untrue because the similarity between fermentation and respirations is that they produce energy, andnot that they both occur in teh mitochondria? Where does fermentation occur then?</p>
<p>platyhelminthes.... no coelom</p>
<p>kaotic spice, so for the very first E question was the answer C basically blocking off platyhelminthes... it was either C or d, AND the second one was D</p>
<p>fermentation occurs in the cytoplsm im guessing, cuz im positive the answer to that question was that both yield eneryg</p>
<p>um... I don't remember what the diagram looked like and where the letters were I think the second one was D though... I switched to Bio M like after the 3rd question in E... ^^; sorry</p>
<p>Yes, fermentation occurs in cytoplasm. There are several ways you could have figured this out:</p>
<ol>
<li>Anaerobic bacteria do fermentation yet have no organelles.</li>
<li>Fermentation yields low-energy so the mitochondria was probably not involved</li>
<li>Glycolysis takes place in cytoplasm and fertilization is a cycle with glycolysis</li>
</ol>
<p>not necessarily for 1, cuz muscles produce lactic acid under strenous excersise and they have organelles</p>
<p>the first question was about true tissues htough wasn't it... so whatever letter started the Eumetazoa branch should be it which is the one that separates the porifera from all the others</p>
<p>true tissues, a pseudocoelom isnt true</p>
