The mechanism of action of Bordetella pertussis is to stop the cilia of epithelial cells from beating.
<em>Bordetella pertussis</em> is a pathogenic, gram-negative bacteria. It is the causative agent of highly communicable respiratory disease known as pertussis or whooping cough.
The mechanism of action of Bordetella pertussis:
- This bacterium colonizes the ciliated epithelial cells of the respiratory airways of the host.
- A surface protein on the bacteria called filamentous haemagglutinin adhesin binds to sulfatides on the cilia of epithelial cells. When the bacterium is anchored, it releases tracheal cytotoxin, which prevents the cilia from beating.
- As a result, the cilia in an organism's lungs are unable to sweep out foreign material, and the body reacts by causing the host to cough. When people cough, bacteria are released into the air, where they might spread to other hosts.
- Another toxin called the pertussis toxin, often known as PTx, prevents adenylate cyclase from using ATP to convert to cyclic AMP. This results in over-conversion of ATP to cyclic AMP, which may interfere with cellular signaling systems. As a result, phagocytes are unable to respond to an infection effectively.

Answer:
The coral take in food from the water and provide shelter for the fish.
Explanation:
Coral reefs found in marine ecosystem and provide diverse ecosystem on the planet. They play very important role in marine ecosystem such as resist the effect of wave action and tropical storms and protect coastlines and provide shelter and habitat to other marine organism such as small fishes.
The image given shows fish and corals exists together and shows relationship between corals and fishes.<em> </em><em>This means, Corals take minerals and food from the water and provide shelter to marine animals. </em>
Like this corals functions in the marine system.
Hence, teh correct option is "The coral take in food from the water and provide shelter for the fish".
