I got a bit stuck on the cystic fibrosis question as well

Report

Cystic fibrosis is the lungs!!

Cystic fibrosis is an inherited chronic disease that affects the lungs and digestive system of about 30,000 children and adults in the United States (70,000 worldwide)

And the Definition of Osmosis is the movement of water molecules through a partially permeable membrane from a region of high concentration to and area of low concentration. Not the other way around :)
