Explanation:
Mitosis is a kind of cell division that produces 2 daughter cells, which are genetically identical to both the other daughter cell, and also the parent cell
Before the parent cell divides, it duplicates all the DNA. With that being said, it means both daughter cells has the completely same chromosomes numbers and the types of alleles.
Different to another cell division, meiosis. Meiosis has daughter cells which has half of the parents chromosomes.
Therefore, the daughter cells will still have 60 chromosomes. The cells are said to be diploid.
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
