Re: Psychology/Sociology Qbank 21, Question 9

Hi uvwaves21, Thanks for the excellent question. This strikes me as kind of a gray area. I think it's clear that wealth transfer would be a manifest function of philanthropy, and that "immortality"—as described by the passage—would be a latent function insofar as it's not to be taken liter...

Re: Bio Questions V1 Passage 8

Hi vpg1993, That's an excellent question. Basically, norepinephrine can act on alpha-receptors to cause vasoconstriction and on beta-receptors to cause vasodilation, so whether it causes vasoconstriction or vasodilation in a given tissue depends on the distribution of receptors (here's a good review...

Re: where are the PDF content review books?

Hi ehrughan, In the emails that you got when you signed up for the course, there should be some links to set up Adobe Digital Editions versions of the textbook -- so I'd suggest double-checking that, and if you don't see the links, filing a tech support ticket (click on the "Need Help?" bu...

Re: AAMC Chemistry Section Bank #8, #12, #20

Hi Ray, For questions 8 & 12, the common thread is the photoelectric effect and the work function. (The photoelectric effect applies directly to Q12, and indirectly to Q8, because breaking a bond means ejecting electrons out of it by definition, so the underlying concept is the same). If you're ...

Re: NS FL3 chm/phys Q13

Hi vgp1993, There are basically two parts to this question: figuring out what they're getting at re: electron orbitals and then linking that to wavelength. Turning to the orbitals, the idea is that electrons in s orbitals (or more "s-like" hybrid orbitals) are held more tightly to the nucl...

Re: OCHEM questions

Hi MCAT_Retaker, Here's a great overview of the topic . The idea is basically that through acid-base chemistry (more specifically, by using a chiral organic acid) you can put a charge on your molecule of interest while deprotonating the acid -- so you take two neutral compounds and convert them into...

Re: Biology Questions

Hi MCAT_Retaker, Re: electrophoresis, the inclusion of "Item 4" is definitely a data entry error that needs to be fixed. Re: blotting, the statement you checked off is wrong in a couple ways. Antigen-antibody interactions are used in western blotting, but not in other forms of blotting (So...

Re: NS FL 9 biochem q13

Hi ds07164, That's an excellent question. I think what's going on is that choice D is tempting if you envision Crispr-CAS as a defective version of the genes required for lipid metabolism, so the question scenario would be similar to a single-knockout model. Instead, as described by the passage, Cri...
