Experiment: A lab tested the impact of smoking on lung cilia by exposing cultured airway cells to cigarette smoke daily for a week.Observation: Smoke-exposed cells showed reduced cilia movement and structural damage.Question: What does this experiment show?

Question

TestUstad · Accepted Answer

Smoking impairs cilia function and may reduce airway cleaning ability.. The correct answer is option C: Smoking impairs cilia function and may reduce airway cleaning ability. The experiment demonstrated that exposure to cigarette smoke led to reduced cilia movement and structural damage in airway cells, indicating that smoking impairs cilia function. This impairment can hinder the airway's ability to effectively clean itself, potentially leading to respiratory issues. The other options are incorrect as they do not align with the observed effects of smoking on cilia in the experiment.
