Answer:
The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
Explanation:
Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.
Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
b. the burning of fossil fuels for energy and transportation
Its a thing used in photosynthesis <span />
As we know that;
Density= mass/volume
By rearranging
Mass=. Density* volume
Mass=. 0.2*45
Mass=. 9 grams
