Re: 2000 Q: Q 1185 Psychology

Thanks for the question! The idea is basically that with more hawks, the likelihood of a hawk bumping into another hawk increases. So, if we did want to say that the W was increased because of the competition, we'd also have to say that the C is increased because of the increased likelihood of becom...

Re: 2000 Q book: Q 843 Biochem

It's more about charge repulsion than it is about hydrophilic interactions. Since it's the depolarization (more +) that causes the opening, the thing blocking the pore needs to be positively charged to be appropriately repelled to open the pore. I'm not sure I totally got your question, but hopefull...

Re: Desensitization VS Habituation

Based on these definitions you could say that, but I really think of these as more psychological terms when applied in this context! In diabetes, for instance, I suppose you could think of insulin as a "stimulus" but we don't really think of it quite in that way in the biochemical context, for the m...

Also, for both mirrors and lenses, if the image forms on the same side as the observer, then it is automatically real? Just confirming. For mirrors, if the image is on the same side as the object, then it's real. For lenses, if the image is on the opposite side of the object, then it's real. There ...

Re: Missing Question? Verbal Quant & Research Methods

Wow, yep, I see that, too! The question must have been lost somehow. I'll let the content team know so we can update it in the next version of the books.

Thanks for sharing and good luck with your prep!

Re: Solubility Content Video

Thanks for the question! When I was studying for the MCAT it had been about 6-7 years since gen chem for me too—keep after it and you'll be able to crush the MCAT chem stuff! I think I see the confusion -- since we're adding 0.05 moles of silver nitrate and 0.1 moles of sodium chloride to 2L of wate...

Re: 2000 Q book: Q 843 Biochem

Thanks for the question! Here's the text from an earlier post on this topic: The basic idea here is that the s-loops allow the protein to change its conformation—or, in this case, you could think of it as its relative position in the membrane. In order to not be blocking the pore (through which ions...

Re: 2000 questions Q 483 and 487 Bio

Thanks for the post!

Yep, Q483 is a known error that'll be updated in the next edition of the QBook.

And yes it looks like Q487 switched answer choices A and B — A is the correct answer. I'll alert the content team.

Good luck with your prep!

Re: NS FL1 C/P Q20

Thanks for the question! Yep, there are some posts on this one. Here's text from two of them: Q20 is really a triangle problem in which you have to integrate the normal force and the turning force. The man's weight is 65 kg so the normal force will be 65 kg * g = 650 N. The turning acceleration is 5...
