(a) The partial pressure of oxygen in the alveoli is 13.3kPa. At this partial pressure of oxygen the total volume of oxygen that is carried by 100 cm3 blood is 19.78 cm at pH 7.4 and 37°C.
The volume of oxygen that combines with haemoglobin at 13.3kPa is 19.48cm 100 cm 3
blood.
(1) Calculate the percentage of oxygen that is combined with haemoglobin in 100 cm3 blood.​

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
