Answer: humoral immune response 
The main antibody isotypes in the influenza-specific humoral immune response are IgA, IgM and IgG. 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.
        
             
        
        
        
Together the insulin and glucagon help maintain a state is known as homeostasis in which conditions inside the body remain steady. 
<h3>
What is homeostasis?</h3>
Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them.

Answer:
Microtubules, like actin filaments, are dynamic structures: they can grow and shrink quickly by the addition or removal of tubulin proteins. Also similar to actin filaments, microtubules have directionality, meaning that they have two ends that are structurally different from one another. I hope this helps :)
