I thought (incorrectly, obviously) that histone kinase also allowed transcription to proceed?

If you got all tangled up on this question like me:

anatomic dead space= conducting airways

Alveolar dead space= alveoli that are ventilated but not perfused (wiki)

physiologic dead space=anatomic dead space+ alveolar dead space

Po2: just no

motherhen  When I get mixed up on dead space vs shunt, I anchor myself on the meaning of anatomic dead space: the parts of the airway that don't have associated blood vessels for gas exchange (nose, trachea, bronchi). From there I work backwards to what shunt means: blood vessels that don't have enough air. +1

Or, if you can never remember MUDPILES: + he is way in renal failure: metabolic acidosis. + respiration 24/min: resp compensation, low CO2 + HCO3 is low (^^renal failure)

tallerthanmymom  Can someone explain why it is an increase in risk rather than a decrease? Also, relative to what? Do we just assume it is relative to people who do not exercise regularly? +  
banana  Uncertain about this, but I think from my memory of the question that the above explanation should say "relative risk" and not odds ratio. The relative risk is the (number women fractured/total exposed)/(number women fractured/total unexposed):: therefore, >1 means that more women got fractured when they exercised. (FA 2020, 258) +1  
drpee  Same risk: RR = 1 (theoretical). Lower risk: RR < 1. Greater risk: RR > 1 +  
blah  I got confused by the question because I was bringing in my own biases (i.e. doesn't exercising decrease the risk of fractures in this population of women?). If you simply read the question as what does a RR>1 mean? No doubt you'll get the correct answer. +4
