The organelle inside the cell that eliminates waste is the lysosome. It contains chemicals that help digest food and worn-out cell parts. <span>When nutrients enter the cell, lysosomes release digestive enzymes to break down the nutrients. If the cell isn't getting enough food, lysosomes will digest other organelles so that the cell does not starve. Lysosomes eliminate worn-out organelles from the cell via the process of autophagy.</span>

<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.
