Answer:
The role of CFTR is to build channels on the cell surface to enable the flow of chloride (Cl-). When the CFTR protein works properly, the balance of Cl-and fluid at the cell surface is normal. If the mutation of CFTR protein happens the balance of Cl- and fluids is disrupted, causing mucus in various organs to become thick and gluey. As a result, lung infections and, eventually, respiratory failure in the lungs might occur. Mutations on the CFTR normally change single amino acids in the CFTR protein which happens in abnormal channel breaks down soon after it is made.
Explanation:
The CFTR gene gives direction for producing a protein called the cystic fibrosis trans membrane conductance regulator. This protein functions being a channel over the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.The channel transports negatively filled particles called chloride ions into and out of cells.The transport of chloride ions improves control the movement of water in tissues, which is essential for the creation of thin, freely flowing mucus. Mucus is a slippery substance that greases and defends the lining of the airways, digestive system, reproductive system, and different organs and tissues.The CFTR protein further regulates the role of other channels, such as those that transport positively charged particles called sodium ions across cell membranes. These channels are essential for the normal function of organs such as the lungs and pancreas.

The answer is because the cell membrane is pressed against the cell wall.
Rabbits produce large numbers of offspring during each reproductive season, yet the number of rabbits within a given population changes very little from year to year. The stability of the population size is most likely the result of environmental factors that keep the population in check (2). Rabbits are seen as food by many predators which will keep the numbers down. The principle of the survival of the fittest will ensure that young strong rabbits get to breed and carry the gene pool to the next generation.
