SATII Biology MAY

<p>What you asked was the question you posted in the post on this page with the winky face after it.</p>

<p>vadox - we know that modern day birds do not have teeth ... however Archaeopteryx (an old bird) had teeth - collegeboard should have been specific including modern day birds</p>

<p>afruff - sorry i see now...but still fermentation produces 2 ATP...</p>

<p>o the huntingtons one, that was hard. if the guy had it and its dominant, then how is it 0 percent again?</p>

<p>Yes, well they were unspecific for a bunch of them; ie savanna or tropical rainforest, plant evolution to go on land, etc.</p>

<p>:(</p>

<p>Fermentation is a process that is anaerobic but makes that switch to get ATP - that's very obvious...</p>

<p>Huntington's i got 50% !!!</p>

<p>well i'll talk to u guys again on May 25 to compare scores...Im really curious with all this debate...au revoir strangers!</p>

<p>@helpneeded&lt;/p>

<p>That site is oversimplifying things. Notice that it says "overall lactic acid fermentation".</p>

<p>Campbell biology has it best:

<p>wait helpisneednow, i got 50 percent for the huntingtongs too, i thought u said that was 0, was 50 percent right?</p>

<p>well, if it was stated that the father was heterozygous, then it would've been 50%. However, I'm not sure whether or not the book stated the father was heterozygous. I thought that the only thing the book stated was the father had the sickness, and that it was caused by a dominant allele.</p>

<p>If thats the case, by simple dominance, the father could've have two cases: AA, or Aa. Because its not certain what the father was, both cases have to be taken into consideration when calculating probability.</p>

<p>Is that right?</p>

<p>it didnt say he was heterozygous, so it couldve been 75 or 50 i dunno how you would kno which one without it telling us. Huntingtons is autosomal dominant and all the problem said was that the father had it meaning he was AA or Aa, what did u put chungsiwel, i made a guess and said 50</p>

<p>does anyone how many you are allowed to get wrong if you are shooting for a 700+? Everyone's talking about getting a 800 but I just want anything above 700.. I can't exactly remember but i think I left about 5 or so blank.
::sigh::</p>

<p>I think Huntington's is immediately fatal when a person is homozygous dominant, like, the person would die in the womb. So the father basically has to be heterozygous or else he wouldn't live to be a father.</p>

<p>so VFrizz that would make it 50%</p>

<p>Yes, it's 50%</p>

<p>VFrizz, did u take E, if so do u remember the one about flatworms, the I, II, or III question</p>

<p>Does anyone have an absolute answer on the food production biome question?</p>

<p>I've heard tropical rain forest, grassland, and temperate deciduous =/</p>

<p>For the flatworms, III was not correct because platyhelminthes do not have a digestive tract. "I" was correct but I wasn't sure about II, so I put down "a". I think platyhelminthes don't secrete toxins as much as nematoda.</p>

<p>tropical rain forest, the collegeboard never intended to make a question that hard, its supposed to trigger a fast response, tropical rain forest</p>
