<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods.

Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
oxygen can only hold two bonds with other elements.
