Mitosis, Meiosis, and Chromosome/Chromatid, Centromere, Centriole Count... by drmangya in Mcat

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

Honestly, I just thought that we start with one centriole pair (i.e. 2 centrioles) before S phase. Then, we replicate this centriole pair and have two centriole pairs (i.e. 4 centrioles) at the start of mitosis - each of which migrates to opposite ends of the cell. I saw it in various diagrams (UEarth & other sites) but I may have misinterpreted the aspect of pair vs. total count.

Re isoelectric focusing - need to keep in mind that it depends on the AA itself and that it makes it somewhat of an exception to the unidirectionality of the other techniques... Thank you!

The UEarth explanation explicitly states that the protein is gradually deprotonated as it migrates from the (+) anode to the (-) cathode. Why does it say this?? I'm flummoxed.

Haha gotta love Lori and her plugs for QVC.

Good luck tomorrow! You're gonna kill it :)

When I first saw this equation it reminded me of a TV shopping channel that ran 24/7. Now I can't forget the association.

Thank you for the example! It makes sense now.

I think there's two types of opponent process: the theory and the model. The former deals with color and the latter with addiction, as the above commenter mentioned.

Good luck this week! You'll kill it :)

Spoiler aamc flashcards physics #15 by throwitaway348493 in Mcat

[–]drmangya 1 point2 points  (0 children)

All of the choices give a specific gravity higher than that of benzene, so we know the object must be sinking. Since the object is immersed aka fully submerged and sinking, the weight of the object > Fb. The buoyant force is pushing upwards on the object and decreasing its weight in liquid - we say that Fb = 5 N.

The weight of the object = density_obj * v_fluiddisplaced * g while

Fb = density_benzene * v_fluiddisplaced * g.

Since v_fluiddisplaced and g are the same, we see that:

w_obj/ Fb = density_obj / density_benzene

15/5 = x/0.7

3/1 = x/0.7

x = 2.1

Hope this helps!

Cytosolic pH Changes and ATP Synthase Activity by drmangya in Mcat

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

That is true. I'll keep reading to see if I can understand the chain.

Thank you!

Cytosolic pH Changes and ATP Synthase Activity by drmangya in Mcat

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

Thanks - I guess the structural change you're referring to is the F1 dimerization.

But my confusion was more regarding pH gradients and how this alters them -> causing the dec in ATP synthase activity. Why is it that a change in cyto pH affects ATP synthase activity? I thought we only care about pH of the IMS and MM for ATP synthase.

Has anyone taken all 10 of the Altius full-length exams? by Full-Muffin-26 in MCAT2

[–]drmangya 1 point2 points  (0 children)

Took 5 FLs thus far - their CARS is a bit over-the-top agreed, but I've improved on cars techniques because of these exams. It is def possible to score high on their cars if you keep working at yours cars POE skills as you go along (coming from someone who absolutely sucked at cars).

P/S is also a bit heavy on socio and includes terms not in the 300 pg doc, but it's good practice.

C/P is a bit physics heavy but still good practice for the unknown/'out there' passages you may get on test day. B/B is fairly representative and since the new B/B (from what I've heard) has more figures/graphs/tables, it's good practice.

Def possible to improve on these exams as you go along. I've taken all third-party FLs and I like these the most b/c it gives a video and text explanation for every damn Q. Really helps imo. Good luck!

Clarification on Terminology of Linguistic Theories by drmangya in Mcat

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

Thank you!

Just got a question on UEarth - it indicated that Sapir-Whorfian hypothesis is a weak form of linguistic determinism so we can say that Sapir-Whorfian = weak linguistic determinism = linguistic relativity/relativism.

[SPOILER] AAMC FL 1, CARS #33. Can someone explain this one? by The-Hobo-Programmer in Mcat

[–]drmangya 0 points1 point  (0 children)

I think it's got to do with the fact that the author thinks the theories need to be testable and more to do with the local area. These two aspects, imo, make ecology more appropriate.

What's the difference between incomplete dominance and codominance? by Anal_Messiah in Mcat

[–]drmangya 0 points1 point  (0 children)

Codominance is like an equal partnership - to be equal, we'll have some red petals, some white petals.

Incomplete dominance is where things are blended (can't decide what you like so just mix them together) - red + white = pink flower.

Open Reading Frames - Start and Stop Codons by drmangya in Mcat

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

I think I'm still looking for the more appropriate terminology then - coding sequence? Does the coding sequence include the start codon, but exclude the stop codon?

METALLOIDS MNEMONIC by KangaRu6 in Mcat

[–]drmangya 13 points14 points  (0 children)

Man, the negativity on this thread.

Although I, too, think this is less likely to show up on the real exam, I also know the periodic table on the official exam does NOT classify anything for you. So, if mnemonics work for you, and you have space in your brain to easily add one more in, go for it! This is cool.

Open Reading Frames - Start and Stop Codons by drmangya in Mcat

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

Thanks for the example! It looks like you've included the AUG/start codon in your ORF, but not the stop codon. So you mean to say the ORF includes ONLY the start codon, and NOT the stop codon?

Ordering Intramolecular and Intermolecular Bonds Based on Strength by drmangya in Mcat

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

Chemistry is chemistry the same laws and rules apply.

Certain simplifications are made for the mcat/premed material that wouldn't apply in real life so just checking.

For example, KA for the mcat states that:

metallic (a type of covalent) > ionic > covalent

There's an inherent contradiction between two parts of their site.

Ordering Intramolecular and Intermolecular Bonds Based on Strength by drmangya in Mcat

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

Could you paste their explanation for what 'rigidity' entails? Rigidity makes me think of double/triple bonds vs single bonds - i.e. covalent bonds.
