Here’s what I found about this
Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.

Answer:
Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
Explanation:
The air travels through the respiratory system during inhalation in the next order:
- <em><u>Nasal cavity:</u></em> You inhale air into your nose.
- <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
- <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
- <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
- <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
- <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
