Re: Chemistry and Bio: Random Questions?

2. I'm not sure which lens you're talking about. Are you referring to the eye?
3. Yes! You got it!

Re: AAMC FL

CP4: I'm not sure what sort of shortcut there is, but I've attached a drawing of how to follow the extra methyl group through the different steps. BB6: If it was X-linked recessive, then the entire third generation on the left should have been affected, since their mother would have two copies of th...

Re: AAMC SB: B/B question 30 (discrete)

1. This is important because we know that for the F2 generation to contain brown beetles, the mating pair from F1 must both be Rr. Therefore, you need to work back from there in order to find the total probability. From the split of the F1 generation, we know that the original mating pair must have ...

Re: AAMC Section bank: B/B Question 17 discrete

1. This should just come with more time and with doing more practice problems. You can also practice writing out palindromic sequences yourself to familiarize yourself with them. 2. This is because Southern blots use restriction enzymes, which recognize palindromic sequences. Since the mutation is d...

Re: AAMC Section Bank BB and CP

CP 40: You described it well! The carbonyl carbon originally has an sp2 configuration, which turns into sp3 as it goes into the tetrahedral intermediate, which then reverts back to sp2 after the amine is eliminated. Keep in mind that we're talking about peptide bond hydrolysis here, so don't let you...

Re: AAMC SEction Bank Discrete Question 25 C/P

Hey! This is not an intuitive topic at all, but what you said is right only when we're building orbitals. When we're taking electrons away, then we take from the s orbital first. Here is a website that explains this in greater detail. https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_...

Re: Section bank C/P: how to avoid this mistake ?

Hey! A general rule is that when you see information that's necessary for answering the question, make sure to read all the surrounding information too. The line about compound 2 yielding similar results as Compound 1 is at the beginning of a paragraph, and a quick skim shows that Compound 2 is ment...

Re: Chemistry and Bio: Random Questions?

1. Lewis acids are anything that have vacant orbitals to accept electrons. For example, H+ is a Lewis acid that can accept electrons from OH-, a Lewis base. Since transition metals can do so, they are considered Lewis acids. 2. The sky is blue due to an effect called Rayleigh scattering, where blue ...

Re: Physics: Should I know these equations?

It's hard to predict exactly which equations you'll need to know for test day. While you don't necessarily need to memorize all these equations, it's good to have at least a conceptual understanding of them and the relationships that they are trying to convey.

Re: What are the differences between Difference between Continuity vs Bernoulli vs Poiseuille's equation?

Continuity Equation: Q=A1V1=A2V2. Q is the flow rate, A is the cross sectional area, v is the linear speed of the fluid. This is essentially saying that flow rate is remains constant within a closed system, even if the area changes. Therefore, the fluid will flow faster through narrow passages and s...
