Mucosal or secretory IgA antibodies are produced locally and transported along the mucus of the respiratory tract by transepithelial transport and can afford local protection from infection of airway epithelial cells.
That statement is true!!!
There are 5 steps of the scientific method
1. Make a question

5. Conclusion ( what you learned from the experiment)
Mammoths, sabertooth tigers, wooly rhinoceroses just a few.
