Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.
Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.
Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.

Answer: Phosphodiester bond
Explanation:
The backbone of DNA consists of deoxyribose nucleotides linked by phosphodiester bridges.
The 3'-hydroxyl of the adjacent sugar of one deoxyribonucleotide is joined to the 5'-hydroxyl of the adjacent sugar by an internucleotide linkage called a phosphodiester bond.
Thus, phosphodiester bond is the answer
