Re: FL 2 Phy Q29

Hi there, good question! Generally it is good idea to think of reduced products having high energy in redox reactions. We see that NADH and FADH2 are the reduced products, based upon the electrons they can carry and donate. While it is true that ADP is oxidized to ATP, this is more from a technical ...

Re: Fl9 BB Q59

Hi again, They could be stabilized by those rings, but that could ruin the conjugation set ups of those rings. If the the two rings were one carbon closer together, or there was a double bond on the carbon of interest, that could be a strong answer. But because the carbon of interest is not in conju...

Re: FL9 BB Q41

Hi again, good question! Refer to the passage for this one, as based on the question we are looking at what most likely occurs.

Re: FL9 BB Q7

Good question! It is correct to think of neutrophils as part of the innate immune system, but they can be sometimes considered part of the cell-mediated response as well. ( see research here ). Specifically in the question stem they establish that this immune response interference occurs because of ...

Re: general question about sympathetic and parasympathetic

Good question! Remember that sympathetic vs parasympathetic is all about "fight or flight" and "rest and digest". They each have a particular goal to accomplish in terms of the balance of the body's resources and systems. "Fight or flight" occurs in situations where you...

Re: AAMC PT CP Q 35

Hi there! For every increase in 100 temperature from the table, the resistance increases linearly along with it. 373K -> 473K, resistance increases by 2.6 Ohms; same for 473K -> to 573K, and then from 573K to 673K as well. Be careful with simplifying the math too much! 293 to 573 is not just a doubl...

Re: The Official Guide

Hi there! The epidermis is composed of the ectoderm, but the small intestine is not. It is part of the endoderm instead. Knowing the differences between the ecto, meso, and endo are all very important so it may be quite helpful to make some flashcards based off the definitions in your books. Hope th...

Re: NS QBANK 5 PSYCH #7

Hey there! This is a tricky concept to master, but remember that the answers must fit specific way the question is worded. In this question, we are asked to address the what teacher's response relates to, not the concept of colors and gender together. The teacher's response perfectly fits a hidden c...

Re: AAMC FL1 C/P #9, 45, 56

Hi there! For #9: remember for SN2 reactions that configuration is always inverted. It is originally configured R with the OH which will be displaced by the Br, turning it into S. #45: This question requires us to use the thin lens formula and magnification. Starting with what's given to us, we can ...

Re: NS FL 1 B/B #36

Hi again, pI is our isoelectric point, or the point at which we will have a net neutral charge. Our anode is (+) charged, so if a protein was to move closer to the anode, it must have more (-) charge character. In this case, modified M subunit containing CK isoforms travel closer to the anode than t...
