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>
