(i) The breathing rates of children and adults are different.
(ii) The breathing of males and females are different.
Explanation:
(i) When I measured the breathing rates of children and adults in my home, I found that the breathing of children is quicker than that of the adults. The reasons can be due to the fact that children have smaller lungs and the oxygen getting inhaled is lesser and they have to quickly breathe more to incorporate more oxygen.
(ii) When the breathing rates of males and females were measured I found that females have a higher breathing rate than the males as the former have smaller lungs.
