Which statement is true? Bronchitis can result in hoarseness. Cystic fibrosis is a genetic disorder that causes thick mucus secr
Natalka [10]

<u>Answer</u>:  Cystic fibrosis is a genetic disorder that causes thick mucus secretions.

<u>Explanation</u>:

  • <em>Cystic fibrosis</em> is a genetic disorder caused by mutations in a gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator).
  • The CFTR protein normally functions as a channel for transport of chloride ions in cells responsible for mucus production.
  • A person suffering from cystic fibrosis produces abnormal CFTR protein or no CFTR protein at all.
  • This is the  reason that thick, sticky mucus is produced instead of the thin, watery kind.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

Generally:

  • It protects the cell and prevents any physical damage.
  • It provides structure to the cell. It prevents osmotic bursting.
