question 10
cigarette smoke can inactivate the ______ of the lungs
cilia
flagella

Explanation:

Cilia in the lungs help move mucus and foreign particles out. Cigarette smoke can damage and inactivate them. Flagella are mainly for cell - movement in some single - celled organisms, not relevant here. Vacuoles are storage organelles in cells and actin is a protein involved in cell movement and structure, not related to the function affected by cigarette smoke in lungs.

A. cilia
