Re: NS FL4 C/P #37

Thanks for the question! We are told that the suspended solids are removed, so that might make up a small amount of the other parts of the tablet that aren't caffeine. So we can't exactly assume that all of the tablet is dissolved, but there's no reason to think that there will be caffeine that isn'...

Re: NS FL 10 CP Q52

From figure 1, the gestational sac diameter at week 7 is about 20 mm. Using the second formula given below ΔV / V0 = (r^3 — r0^3) / r0^3 we can input 1/2 of the diameter we determined from the figure (and the one we were given in the question stem). So, r1^3 doesn't actually equal 10, it equals 1000...

Re: glycolosis vs. gluconeogensis/pfk2, pfk1, fructose 2,6p

Hi Shaun, It seems like you are really diving into this metabolism stuff! For the purposes of the MCAT, what I call the "accounting" of metabolism (following the step-by-step reactions, role of each group, etc.) is not very likely to be tested. So I wouldn't worry too much about it, but you can defi...

Re: Content Review Video vs Content Review Books.

Thanks for the question! I wouldn't necessarily say they're simpler than the books, just that they aren't necessarily as wide in scope. It's most helpful to use both together, rather than relying on only one by itself. I would focus on those parts of the chapters that you really need to improve on r...

Re: huckel's rule/conjugation and aromaticity and resonance

Conjugation and aromaticity are similar concepts, but aromaticity has more stringent requirements. All aromatic compounds have conjugation, but not all conjugated molecules are aromatic. To be aromatic there must be pi bonds that lie within a ring structure and it has to follow Hückel's rule. Conjug...

Re: NS Physics Ch. 1 Passage 1 Q2

Hi Kevin! To solve Q3, we basically have to set up a triangle and then do some trig functions to determine the unknowns that we're interested in. We know the man will be falling on his outstretched arm, so we can take the force along the arm as the hypotenuse. This value must exceed 1150 N in order ...

Re: siRNA vs. miRNA

Remember, a scale will always be recording the normal force, so when accelerating in an elevator, the normal force will change. The force of gravity won't change either, since this is a constant. The net force will change though due to the acceleration of the elevator. If there is no acceleration in...

Re: siRNA vs. miRNA

Hi Shaun, Frankly, for the purposes of the MCAT miRNA and siRNA have essentially the same function which is to regulate translation by preventing the transcription of mRNA! They do have differences, but getting into them is pretty specialized and obscure. The best ways to tell them apart are by thei...

Re: Lesson 18-Timed MCAT Practice Passage on the Doppler Effect

Thanks for the question! The basic concept here is that the frequency change will allow us to determine the direction (relative to us) that the car is moving. If the frequency change is negative, that indicates that the vehicle (or object of interest) is moving away from us. If the frequency change ...

Re: reynolds number

It's not too likely that you'd be asked to use that equation. It's more likely, if that topic were to be tested at all, that a conceptual understanding would be required rather than a specific equation like that memorized. It'd be good to know the relationships and the general trends that the equati...
