What are the major processes of the respiratory system?

Inhalation and Exhalation Are Pulmonary Ventilation—That's Breathing. ...

External Respiration Exchanges Gases Between the Lungs and the Bloodstream. ...

Internal Respiration Exchanges Gases Between the Bloodstream and Body Tissues.

 The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.

Explanation:

Option). enzymes cut out the erroneous part and then use the complementary DNA on the intact strand to add the correct nucleotides

Explanation:

DNA errors can be defined as errors that take place occasionally during DNA replication, when the DNA polymerase adds a wrong base to the growing daughter strand.

Many enzymes, such DNA polymerase and ligase are involved to repair these errors. The repairing enzymes first cleaves the mismatched or incorrect base as it has exonuclease activity. Then,DNA polymerase adds the correct base by using information from complementary DNA on intact strand and DNA ligase seals the gap.
