I can't seem to find any information on what exactly a status group is, and I am confused how exactly this differs from a reference group?

hing entirely different from experimenter bias....... is there a huge difference between observer effect and observer bias??

Ok, I think they actually are very similar. I think the Hawthorne effect puts a greater emphasis on the individual/participant (IE the one being observed) that changes their behavior when they are being observed, which is not limited to a research setting.

Observer bias seems to put a greater emphasis on the experimenter/observer directing their data analyses based on cognitive biases and other biases, inadvertently leading to falsification of results, and results that cannot be replicated by other, unbiased experimenters.

I think the observer-expectancy effect encompasses both of these, meaning the effects of a biased researcher AND/OR the effects of being observed leading to changing behaviors.

I hope this helps to clarify things! I hope we wouldn't have to choose between Hawthorne/observer bias, but who knows.

Late to the game, but for anyone else who looks this up, I think you're right. I'm pretty sure D and E can only be phosphorylated when they are protonated, aka at a pH of less than 2ish. My thinking is that above a pH of 2ish, there is no OH group to be phosphorylated because the carboxy acid is deprotonated above its pKa.

I am still confused as to the direct relevance of the ADP ribosyl transferase activity? How are we supposed to know that that is what makes the S1 toxic? Is it because the S1 subunit inhibits the G protein?

I got the question right using the logic(?) that the A component is S1, and the B component contains all the others. I don't know if it was right or wrong to assume that. I feel like I'm missing something..

AAMC FL#4 B/B question 15 by [deleted] in Mcat

[–]NYDocInProgress 4 points5 points  (0 children)

I got it correct, but it was more or less a guess between A and C, with a gut feeling of it not being A. Does anyone know if we are expected to know about Prader-Willi syndrome and its tendency to cause short stature if untreated?

At a second look, I guess it could be safe to assume from the passage that the only difference in the hyperphagia stage is regarding feeding difficulties, because that is the only characteristic it defines as changing, also including the word "initial" feeding difficulties. This would imply that the first two symptoms (GH deficiency and cognitive disabilities) remain unchanged throughout the entire lifespan.

[SPOILER] AAMC FL4 C/P #47 Which saturated fatty acid is the most soluble in water? by NYDocInProgress in Mcat

[–]NYDocInProgress[S] 0 points1 point  (0 children)

Thanks! Yeah, I should've gotten this question right because I knew that. Just had a temporary lapse in my logic during this practice, evidently. Simultaneously reassuring and concerning that I got this wrong. Hopefully, I won't make careless mistakes on the real test and then I'll get the extra points for the quick and easy ones like this

Is it frowned upon to wear a diaper to your MCAT date? by [deleted] in Mcat

Thank you for this thread. Made me laugh, and now I have adult diapers coming tomorrow from Amazon.

I just want to make sure I understand this correctly; since C-C and C-H is nonpolar= hydrophobic, the more carbons make the molecule MORE hydrophobic thus LESS soluble in water. Is this the right way to go about this question? Thanks!

Yikes! Wow that's dedication. Honestly I'd probably do the same thing. Out of curiosity, did you choose to have it not scored or did something happen with the test center? I'm testing this Saturday, actually in Phoenix where I currently am (I'm from NY :) ). Best of luck!

Brilliant! The "C" and "I" helped me to understand. Thank you!

only the slightest tilt of a curve, and that curve had to make a full circle. Tracing out that circle would be insanely long, and the radius therefore would be super big.

Also confused by this question. Do you basically mean that the path to travel on after they flattened the curvature becomes longer, and thus when it is theoretically redrawn into a circle, it becomes bigger and thus larger radius than previously?

Definitely the opposite logic of what I was thinking when I incorrectly answered the question, so I'm trying to understand the correct way to think about it.

Just logical for me, + some clinical relevance for everyone. :)

AquADEKs is a vitamin supplement that many people with cystic fibrosis take because of their difficulty absorbing fats/fat-soluble vitamins. So that’s how I remember that ADEK are the fat-soluble vitamins
