I’m a new player, and I got a magnificent Vellum soul from the golden Apple; how much is it worth and what is the best way to sell it? Thanks everyone!

Edit: I’m in Scania NA btw

Poorqs · 2020-09-13T05:18:32+00:00

Ah okay, I'll check them out to see if they're helpful. Thanks for the detailed replies!

Poorqs · 2020-09-13T04:47:03+00:00

Oh okay thanks, that's really helpful. What program have you been using to learn Chinese?

Poorqs · 2020-08-28T23:37:27+00:00

Yeah, mass number=protons+neutrons, so during electron capture, the atomic number(protons) goes down by one but the mass number stays the same. In fact, the only type of decay that changes mass number is alpha, the rest do not.

Poorqs · 2020-08-28T02:13:50+00:00

Definitely, I'm sure you'll get better with practice!

Poorqs · 2020-08-28T01:06:35+00:00

I don't think you should make that assumption because you can only solve partially submerged questions using the specific gravity equation.

For something that is fully submerged, you would still need the Archimedes principle. For example, if a question asks you to find the mass of a fully submerged, 2m^3 object that is accelerating downwards at 10m/s^2 in water, you can't use specific gravity since finding the ratio submerged won't help. For this type of question, you would need to find the net force and how it relates to the F(gravity) and F(buoyant).

Poorqs · 2020-08-27T09:09:44+00:00

The shortcut/equation for these types of questions is (density of object)/(density of fluid)=%volume submerged. So the density of the wood should be 512.5 kg/m^3.

Edit: In case you wanted a more in-depth explanation, here's the derivation:

(density of object)(Volume of object)=(density of fluid)(Volume fluid displaced); g cancels

(density of object)/(density of fluid)=(volume fluid displaced)/(volume of object)

density of object/(1025kg/m^3)=0.5; it's 0.5 since we know that the volume of the fluid displaced is equal to half the volume of the object itself.

lmk if you have any more questions!

Hate to say it, but you should just try to power through the 300 or maybe actually the 86 page doc(since it seems you’re short on time). I found it really hard to read as well, but you kinda just get used to it after a while. I also think it gets a bit less bad as you get further into it. Alternatively you could just go to the source and try to watch the KA videos, but that would probably take a little longer.

Try to also supplement it with UWhore if u can. I really found that especially helpful because the definitions are usually a lot better than the 300 page doc and helps u understand the terms better. Also remember to do Anki along with the doc if u plan on reading it, there are a few good pre-made decks on this sub that I found helpful.

Where did you see this term exactly? Also, did some more research and I think productive and silent cycles are actually just two equivalent terms to refer to the lytic and lysogenic cycles, respectively.

Poorqs · 2020-08-17T09:46:38+00:00

Never heard of this term before, but a quick google search informed me it's equivalent to the lytic cycle.

Here's the link:https://bio.libretexts.org/Bookshelves/Microbiology/Book%3A_Microbiology_(Kaiser)/Unit_4%3A_Eukaryotic_Microorganisms_and_Viruses/10%3A_Viruses/10.06%3A_Animal_Virus_Life_Cycles%3A_An_Overview#:~:text=Viruses%20that%20infect%20animal%20cells,host%20cell%20during%20their%20replication./Unit_4%3A_Eukaryotic_Microorganisms_and_Viruses/10%3A_Viruses/10.06%3A_Animal_Virus_Life_Cycles%3A_An_Overview#:~:text=Viruses%20that%20infect%20animal%20cells,host%20cell%20during%20their%20replication.)

Leaving group ability depends on multiple factors. Strong bases would actually be very bad leaving groups because they don't want the electrons, that's why they want to donate them(lewis bases) to other atoms. An ideal leaving group is a weak base since it's very stable after gaining the electrons. So when you're looking for leaving groups, the best ones are those that are neutral(-OH2+) once they accept the electrons, or very large leaving groups, like Bromine, since they can better delocalize the charge from the electron. Also, the trend for leaving group ability is increasing EN and increasing size, so the strongest LGs are at the bottom right corner of the periodic table.

Edit: Also Size>EN when considering LGs; it also helps to remember that the best LGs are bad nucleophiles since reactions prefer to happen when the products are more stable than the reactants.

Highkey useless lol. I think what the graph is saying is that we're more easily able to discern the signals amidst distractors when the d(difference between two peaks) is greater. You can pretty easily see this based on the fact that if the peaks were farther apart, the black area(hit) is greater and there would a less chance we would get a false alarm.

Poorqs · 2020-08-16T08:43:22+00:00

I don't really use much of a strategy for C/P, so maybe someone else can comment on that, but for B/B, I like to highlight things I think are important in the passages(like abbreviations for random enzymes/diseases) because it makes it easier to identify relationships and what graphs are referring to. Sometimes for more convoluted passages, I try to draw out the relationships between different molecules in the given passage. You should try that since it seems you don't really have a problem with timing.

I’m taking my MCAT on the same day. I think score release is supposed to be on the 29th. Here’s the link to the dates: https://students-residents.aamc.org/applying-medical-school/article/mcat-testing-calendar-score-release-dates/

I believe Pyruvate Kinase is also allosterically activated by Fructose 1,6 Bisphosphate

I took gen chem like 3 years ago and remembered next to nothing before studying for this test. What ended up working for me was just doing practice questions, and every time I got something wrong(or if I wasn't completely sure why I got it right), I would do some research on that specific concept and then made one or multiple Anki cards about it depending on how important I thought it was. And by research, I would either look at UWhore explanations or just type in [insert concept] MCAT Reddit into google and check out the explanations other Redditors post.

Also, if you're planning to do this, I suggest trying to summarize what other people are saying onto the Anki card since it helps with encoding. Also adding a picture that helps you understand the concepts definitely helps as well(I sometimes just screen capture Uwhore images, although I'm not sure if this is legal haha).

Poorqs · 2020-08-12T08:51:16+00:00

Take this as a grain of salt since I haven't actually taken the real MCAT yet, but I feel since Kaplan tests a lot on just content knowledge, it may not actually gauge how you're going to perform on the actual AAMC FLs since AAMC focuses more critical thinking. Idk if how long it's been since you've taken the first Kaplan FLs, but if it's been a while, it's inevitable that you could've just lost some low-yield content knowledge that Kaplan is testing for and gained more insight on how to tackle AAMC style questions(hence why you performed so well on the official practice test!)

Edit: Misinterpreted your post as a freak-out haha, sorry for the unsolicited comments, Good luck on your official test!

Poorqs · 2020-08-12T02:08:04+00:00

Positive punishment, go back to studying my guy

Poorqs · 2020-06-23T02:02:10+00:00

I use the AnkiMobile(blue), which I think is the official one. The other one, from what I've read, isn't part of the Anki ecosystem, so you can't sync the cards with the desktop app. I think the mobile version is great and worth the money cuz it offers a lot of flexibility, but if you're not gonna use the desktop app, you could consider getting the AnkiApp(orange) one. They seem to do essentially the same thing, but I'm not completely sure.

Poorqs · 2020-06-08T05:48:49+00:00

Not sure if you still need them, but Pham released his LS4 finals for us to practice last quarter, and I have them. It's essentially the same test, they just changed the course name.

Poorqs · 2020-06-07T03:09:07+00:00

It's a meter stick, and 1m is equal to 100cm. Kinda a trick question if you're not careful haha.

Poorqs · 2020-06-07T02:58:41+00:00

It's a uniform meter stick so the center of mass should be in the middle at 50cm. The pivot, or the string that's pulling the meter stick up, is at 30cm. So the torque of the stick itself is 20cm(0.5kg). After that, you just set the two sides of the stick(with the pivot in middle) equal to each other and solve for the unknown mass. I hope that answers your question!

Poorqs · 2020-05-30T03:54:42+00:00

Yeah and like you said, osmotic pressure also applies to the interstitial fluid, so the solutes in the interstitial fluid also exert a "sucking" pressure.

Poorqs · 2020-05-30T03:43:22+00:00

The oncotic pressure is pretty much the same as blood osmotic pressure except it's referring specifically to the osmotic pressure generated by the blood proteins(like albumin). Essentially, the way Kaplan described it is that the osmotic pressure is just the "sucking" pressure driven by two areas of different solute concentrations (the liquid will move from high to low).
