<p>so its where platyhelminthes ended which was C
E was separating some divisions in arthropods and D was separating echinoderms and chordates</p>
<p>internal fertillization... how else would the female bird be fertillized? there's external fertillization but doesn't that only work if there's water around? I've never heard of an asexually reproducing bird either....</p>
<p>and did u get the ovary as the cell</p>
<p>@nmheta4</p>
<p>Just think about the question again. If something with no complex organellles can do fermentation, then that means that fermentation does not take place in the organelles.</p>
<p>helpneededrtenow - yes</p>
<p>kaoticspice, i was thinking in a sense that BIRDS LAY EGGS isn't that called internal reproduction. Also, the old bird, Accetoyxyl (sp?) had teeth...
LOL i know what internal fertilzation means - but i think im confused w/internal reproduction - is it reffering to ferttilization or laying the egg (for fer. it's internal, laying egg is external)</p>
<p>hey did u guys get tall, pink for one
and 0% for another
i put day 1 for the question w/ bacteria and urine... anyone else?</p>
<p>for fermentation i said they both yield energy</p>
<p>i got tall pink for one, the last question on that secion Rr x Rr was 50 percent, i think i remember a 0 but i cant put my mind on it. Do you remember the one where it was like if tall was injected or something in dwarf wat happens, i put all tall cuz law of dominance</p>
<p>Internal reproduction means internal fertilization. the only external fertilization occurs in fish.</p>
<p>@helpneededrtenow</p>
<p>i did not take this exam, but fermentation does not directly yield energy. It oxidizes NADH to create NAD+ for glycolysis to use so glycolysis can continue to make ATP.</p>
<p>simple dominance an answer for one of the questions?</p>
<p>for the 0% it said which one gives white and tall,
so you cross test:
TtRR and Ttrr - i actually don't know
also, did u get I and II for the one that gave numbers (III was they were on same chromosome)</p>
<p>yes i got simp. dom.
and ATP comes from fermentation - 2ATP = then how else would we get energy ;)</p>
<p>it was 0%</p>
<p>for the huntingtons disease one, i don't recall it saying whether the father was homozygous or heterozygous, meaning both cases would've worked.</p>
<p>so i did: 50% + 25% = 75%</p>
<p>i'm confused now... is the Archaeopteryx considered an actual bird? was internal reproduction one of the answer choices? i thought it was refering to fertilization not the egg... i don't know anymore <em>sigh</em></p>
<p>No helpneededrtnow</p>
<p>This is a common misconception and I already asnwered your question in my last post. Read it again please.</p>
<p>see THAT was what i was thinking</p>
<p>^ it was definitely teeth. Birds do NOT have teeth. Period. Think of an eagle swooping down to catch its prey. No teeth</p>
<p>What did I ask - wasn't that solved 5 mins ago...</p>
<p>Archaeopteryx and theropod dinosaurs have teeth on both the maxilla and premaxilla</p>
