Questions Regarding Cystic Fibrosis. See Details?

-What specific part of the cell/structure allows the mucus secretions to be thick and viscous rather than fluid (i.e., is it a membrane channel, organelle or something else)? Please be specific and describe the step-by-step mechanism whereby this altered structure/part of the cell causes the secretions to contain less water.
-Why does Alvin have salt crystals forming on his skin? Explain the mechanism for this.
-What is the accepted treatment for children with cystic fibrosis? Make sure to list at least three and explain why they work (i.e., what is the purpose of each individual treatment).
-List and explain the mechanism of at least two experimental treatments that are currently being tried to help patients with cystic fibrosis.
