Re: Vehicular vs positive vs negative control

I think this Anki card is wrong since not touching sterilized spheres would theoretically result in a bacteria count of zero. In this situation, it would serve as the negative control, not the positive control

Re: Chemistry and Bio: Random Questions?

Hi! Hopefully this website can help clarify some of your questions about complementary colors. https://www.chem.purdue.edu/jmol/cchem/color.html I don't believe the lens of our eyes absorbs color since its primary role is to focus light onto our retinas Here is a website that further explains Raylei...

Re: Parabola vs Hyperbola shape

Most commonly, you will see a parabola opening up or down. A hyperbola usually opens to the left or right, like with the Michaelis Menten graph. These two shapes come from very different mathematical formulas, even though they may appear to be similar. Here's a website that explains further. https:/...

Re: Vehicular vs positive vs negative control

I think I might be getting confused about the experimental setup. Is the experiment measuring the amount of bacteria on the hands or on the spheres? What are they trying to test for? You're technically correct about the negative control, although most experiments would not do that since they want to...

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_...
