Answer:
O2 affinity depends on the pCO2 and pH.
Higher pH -> Higher O2 affinity -> Higher O2 saturation at higher pH level
Higher pCO2 -> Lower O2 affinity -> Higher O2 saturation at lower pCO2 level
This is a benefit because it allows the affinity of Hb in venous blood conditions (lower pO2, higher pCO2, and lower pH) to be much lower than in arterial conditions. Therefore, when blood goes from arterial to venous, the oxygen concentration decreases much more dramatically due to more oxygen (around 2x) being released to the tissues, which is possible due to the changes in affinity caused by the Bohr effect.

Ok?.... why are you telling us this is it a question?
The number of ways the skaters can finish the competition is 40,320 ways
The different ways 3 of the skaters finish first, second and third is 56 ways
Given the following
- Number of skaters featured = 8 skaters
If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:
8! = 8*7*6*5*4*3*2
8! = 56*30*24
8! = 40,320.
The number of ways the skaters can finish the competition is 40,320 ways
If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:
8C3 = 8!/(8-3)!3!
8C3 = 8!/5!3!
8C3 = 8*7*6*5!/5!3!
8C3 = 56 ways
Hence the different ways 3 of the skaters finish first, second and third is 56 ways
