Final answer:
Stationary adhesion of neutrophils is caused by the binding of molecules near an adhesive surface. Neutrophils play a key role in the immune response by adhering to infected or injured tissues. The stability of adhesion clusters is maintained by the constant binding and unbinding of molecules at the adhesion sites.
Step-by-step explanation:
Stationary adhesion of a neutrophil is caused by the binding of molecules near an adhesive surface. Neutrophils are white blood cells that play a key role in the immune response. When an infection or injury occurs, neutrophils are attracted to the site and adhere to the surrounding tissues to combat the infection. The stability of the adhesion clusters is maintained by the binding and unbinding of molecules at the adhesion sites.
