<p>Same here with the exoskeleton. </p>

<p>Scigirl, what was your question?</p>

<p>Was the answer to the Tay-Sachs question lysosomes?</p>

<p>That’s what I got.</p>

<p>Mendel = quantitative experimenting</p>

<p>Shizzle…my question was if I took E, skipped 2 and got 7 or 8 wrong, what would my score (or score range) be??</p>

<p>for tay sachs i put lysosome at first but then i reread the question it was like it can’t produce enzymes properly so i switched it to ribosome : /
idk tho</p>

<p>Scigirl: I think you’re looking at about 740-760.</p>

<p>what is omit 1, miss like 3
took E</p>

<p>If I took M, missed 5-6 (omit 0) what do you think my score range would be? The score conversion charts I found online vary quite a bit…</p>

<p>I think the tay sachs question should be lysosomes–the little organelles lack the enzymes needed to break up lipids</p>

<p>The huntington’s one was 75 percent!</p>

<p>50 percent if the male is heterozygous and 100 percent if the male is homozygous…
75 percent!!!</p>

<p>kzhi2u: 780-790
aznjonny: If you answered all of them then probably a 760-770. </p>

<p>These are going off what I remember from the CB blue book.</p>

<p>Huntingtons again?? Did they not say it was an autosomal disease?</p>

<p>what was the nutrient the carnivorous plant needed. I put nitrogen but i wasn’t sure…</p>

<p>Nitrogen. 10char</p>

<p>Yes. ^</p>

<p>10char</p>

<p>It’s 50%, people who are homozygous for Huntington’s die early.</p>

<p>50% </p>

<p>Dd x dd</p>

<p>50% show dominant phenotype while 50% show recessive. Huntington’s is dominant, hence the answer is 50%</p>

<p>Is a 740 or 750 considered good?</p>

<p>“5 and 6 is correct. Since its recessive both parents must have a recessive allele for the child to have the disease.”</p>

<p>False - It never said it was recessive.</p>

<p>It only said it was autosomal.</p>

<p>Therefore it could have been dominant, and 6 is the only person that 100% has to have the allele. 5 doesn’t necessarily have to have it as well.</p>

<p>^^^yes10char</p>

<p>yes to scigirl********</p>

<p>but no to xombie, i’m pretty sure that if it was dominant, the disorder would have showed up somewhere else instead of just one person</p>
