what is happening in this stem? unable to occlude the radial artery ? Can someone please explain?

lilamk  I chose atherosclerosis because they said “radial artery is non-pulsatile but remains palpable even as the cuff is inflated”--> my reasoning was that normally you can’t feel the artery anymore once you overflate the cuff bc this occludes blood flow and arteries are squishy (compliant); BUT if you had atherosclerosis, which is literally a hardening, you would not be able to compress the artery, and neither would you expect the normal radial (outward) expansion of an artery during systole. (that is, the pulses!)
mnemonia  I think athero is just a subtype of arteriosclerosis. Also my thought process was (like Lila) if something were to not be palpable then it would have to collapse and athero prevents this from happening.

Can someone explain why the correct answer for the question here is conjugation but can’t be transposition?

catacholamine16  Transposition is when a segment of DNA (in this case, coding for resistance) jumps onto a plasmid within the same bacterial cell. That plasmid might then transfer to another nearby bacterial cell via conjugation. Transposition is happening WITHIN the bacterium. Conjugation is how that resistance gene gets transferred. +5  
lsmarshall  Also, E. coli is the classic example of a bug tat uses conjugation. ^but explanation above is correct^ +2  
seagull  I think he might have did what I did. I got Transformation mixed up with transposition. FML +2  
luciana  I still can't understand why it can't be transduction. Is it just because of bacterial types? +  
thotcandy  @luciana Yes, I believe so. You have to remember which bacteria have a conjugation pilus - E. coli is the most popular one because of its F sex factor (remember the F+ x F0 thing in FA?) +
