<p>yeah, the colorblind boy was 1/4.</p>
<p>and i’m pretty sure that the colony one is 80,000. It’s a simple math question, i did it 3 times and got the same answer.</p>
<p>lets say that 1 mL has 1000 particles.
diluting it to 1000 mL (that is, 1 L) would mean there are 1000 particles/1000 mL.
Taking 0.1 mL of that 1 L ((1000*0.1)/1000) would give you 0.1 particles/mL.</p>
<p>Now, just taking 0.1 mL of the undiluted 1 mL is (1000*0.1) that is, 100 particles.
That means the second solution has 100/0.1, or 1000 times many particles as the first.</p>
<p>80*1000 = 80000.</p>
<p>Voila!</p>
<p>@ionlyflyaway the one with 3 unafected sons i think they said was autosomal recessive so it wasnt sex linked. I put that the sons would be heterozygous or w.e. it was …(A) i believe.</p>
<p>@mystic1996 i think it was 1/2 for the boy bc if the dad has it he has X<em>Y and the mom would have X</em>X bc one of their daugheters i believe had it already. So the cross would end up with offspring for the male X*Y and XY which is 1/2</p>
<p>Yes it was 1/4 for color blindness , and concerning the parasite one it is the one that doesn’t kill its host</p>
<p>@bmonticello
You’re assuming that it is given that the offspring is a boy.
It was asking for the probability that it was an affected boy, not the probability that a boy would be affected.</p>
<p>hey guys, do you think the test was a little bit harder than the practice tests or released exams by collegeboard. Those tests give 800 when you miss 5. I took those tests and they were MUCH easier. I hope there is a bigger curve. XD</p>
<p>Yeah protist and plantae</p>
<p>@insurrection ADSLKFAJDSLF DAMMIT</p>
<p>@bmonticello I also got the heterozygous thing. But for the boy, the question asked what is the probably that they will have a boy who is colorblind. Their probability of having a boy is 1/2 and the probability of that boy being colorblind is 1/2. Don’t you multiply the two?</p>
<p>for the conjugation question where it said if you stop conjugation half way…what was the answer…i think i put find the spot of a gene or something?</p>
<p>@mystic yeah i assumed they were asking only if they produced a boy what is the prob that he is colorblind…dammmit…w.e. maybe i put 1/4 idk…i put that for something i know for sure lol</p>
<p>bmonticello23, you are right. The answer was helping find order of genes on chromosome</p>
<p>was the question with the graph which rose and then abruptly dipped down to 0 that the protein/enzyme thing denatured at 40 degrees?</p>
<p>It was to detect the position of the gene
And the probability was 1/4</p>
<p>yeah insurrection thats what i put</p>
<p>Yes i got the denatured thing. Ugh so annoyed at the parasite question I got that wrong grr</p>
<p>crap now im at -5 damm</p>
<p>Lol I’m at like -10 so don’t worry about it.</p>
<p>hey, what did you guys get for the control one, where the apex of the plant was cut. It was the uncut, cut with nothing added, and cut with lanolin?</p>
<p>@YomnaAyman, yea i put 1/4 too for the probability of the colorblind boy</p>
<p>I didn’t have the uncut as a control. I put cut with nothing added (II) and cut with lanolin (III) as the controls.</p>
