<p>what the crap… how do diploids and haploids play a role in this quetsion?</p>
<p>what do u guys think -6 or -7 wud be</p>
<p>What did you guys put for “what must occur for a mutation to effect evolution?”
some answer choices, if i remember correctly:
the mutation must be in a gamete
mutation must be present in all individuals of a population
mutation must affect the heart</p>
<p>I put that the mutation must be present in all members of a population because I remember reading something like an affected individual will not affect natural selection; therefore it cannot be the gamete answer.
Can anyone second that?</p>
<p>@DitzyDino</p>
<p>I put the gamete answer.</p>
<p>The mutation doesn’t have to be present in all individuals of the population, because if it is in a certain number of individuals and it is a good mutation, then those animals will be selected for while the ones without the mutation will be selected against. So, eventually all the individuals in the population that lacked the mutation would no longer reproduce, while the ones that had the mutation would be reproducing.</p>
<p>Anyone else agree? o.O
This was just another one of those questions where it seemed like it could be two answers… gah…</p>
<p>it was gamete</p>
<p>Shoot, you’re right. I didn’t think of that.</p>
<p>for the polyploid and diploid one i put down that it would occur more frequently in diploid plants or i put that it happens less frequently in polyploid, same answer, this is because in a polyploid plant there are more chromosomes that have the possiblitity to mask the trait than a diploid one</p>
<p>^ i dont think that was a choice.</p>
<p>“james1212123” but there was also another choice that was like “there is less chance of a recessive trait occuring than in diploid plant” and “there is more chance of it occuring in a haploid species”</p>
<p>Did anyone put that its the same for the polyploids and diploids? Thats what I put, but i think its probably wrong…</p>
<p>okay some people were wondering about the curve that someone was talking about on a released exam- idk what year this was but this is the Collegeboard released exam curve…and it was easier than this exam…</p>
<p>OH THIS IS FOR M…E is easier by like a point approximately (73 is an 800)
74-80 = 800
72-73=790
71=780
69-70=770
68=760
66-67=750
65=740
64=730
62-63=720
61=710
59-60=700</p>
<p>okay if anyone needs beyond that you can PM me :)</p>
<p>^no way in world would that be the curve</p>
<p>77 or 76 is the raw score cutoff for 800</p>
<p>well idk it was the released exam…so im hoping it’ll be like -4 or -5 will be an 800…sigh one can wish…</p>
<p>for the question about diabetes mellicus… was the answer Amino Acids, and not glucose?
[Effect</a> of protein restriction on sulfur amino acid catabolism in insulin-dependent diabetes mellitus – Hamadeh and Hoffer 284 (2): E382 – AJP - Endocrinology and Metabolism](<a href=“http://ajpendo.physiology.org/cgi/content/full/284/2/E382]Effect”>http://ajpendo.physiology.org/cgi/content/full/284/2/E382)</p>
<p>^^^was that the one in the Official Study Guide or did u buy another Bio SAT II exam?</p>
<p>I am pretty sure the answer was glucose since it had to do with diabetes</p>
<p>yes the diabetes question’s answer was glucose, as your beta islets of langerhans are not working so there is no insulin and thus, glucose in the urine.
And it’s rna-rna definitely
also, does anyone know how big the curve CAN be, like have scores like < 77 ever been an 800?</p>
<p>are you sure adiboo?
where did you get that info? can I have the site for it?</p>
<p>It’s in the book pinkumbrella, the collegeboard book i believe.</p>
<p>Anyone know when we get our results back?</p>
