June 2008 Biology E/M

<p>why would it be sex linked?</p>

<p>i said that it was autosomal recessive..</p>

<p>idk the exact numbers, though I do recall both men and women being affected. First generation were both heterozygous normal people which produced like 4 kids, two of which were affected (one boy and one girl). I remember this because there was a question that asked about inheritance and a wrong answer choice was "its impossible for a brother to have it but not a sister to have it" or something like that. Clearly in that second generation there was a brother and sister that had it.</p>

<p>did the solution X question I, II, III type say it was after 24 hours? B/c if it did, I look at several sites and they say that there would be no net movement of water(isotonic)--> equilibrium and wouldnt that happen after a day?</p>

<p>the pedigree is impossible to be sex linked because 1) the instructions on top said A=dominant and a=reccessive. Just that alone told us that there is nothing to do with ANY sex linked diseases, and 2) there were almost equal amounts of guys and girls that were affected</p>

<p>Exactly equal, if I remember correctly.</p>

<p>o, well it certainly is autosomal recessive</p>

<p>Ok can some1 add on to the comply list.
We should have 47 questions (autosomal recessive and the 24 net movement one).</p>

<p>Wat were the choices for the Lavender Flower Leaf structure question with the tight leaf arrangement?</p>

<p>Wat was the answer to that?</p>

<p>So anyone know what -12 will get some one on this test?</p>

<p>@132
i said the petal was homozygous. for the 1st question
and then incomplete dominance for the 2nd one
and lets say Tt=lavender, then, tt=white, and TT=blue, so the whites ttxtt=all tt. So 3 i got 100% white.</p>

<p>No the Lavender was incomplete dominance
Im talking about the leaf structure. I put Simple dominance for the tight leaf structure question. Am I right?</p>

<p>@132: I dont think there was a question that asked for tight leaf inheritance pattern, but if there was - ya simple dominance.</p>

<p>So what's the Bio-M curve gonna look like? Similar to the one in the CB book?</p>

<p>with the diffusion over the membrane one....itsaid water would become isotonic and sugar would stop moving after 24 hours--is that detailed in the experiment--would it be wrong because its an assumption?</p>

<p>tick629 I had the same exact thinking which is why I put isotonic and it ended at the 24 hr period... tricky cb lol</p>

<p>That question was like an SATI CR question lol. I didnt put isotonic/ended at 24 hr period only because I was wary CB was trying to fool unsuspecting testers. The more I think about it, the more I think those are viable assumptions...but I went with the bare minimum on that question lol. No assumptions for me.</p>

<p>Equilibrium doesn't mean that the reaction has stopped... There would still be solute entering and leaving the bag in roughly equal amounts</p>

<p>Just curious, did anyone get perfect?</p>

<p>i think we should compile a list of all the answers on the test. that way we have a better idea of how well we did. here is a continuation of the list asc3nd started. just copy and paste on more answers as you think of them. :)</p>

<p>ok, last question regarding the cancelling thing. i've pretty much made my decision, but do colleges see a test date and no score or nothing at all?</p>
