This articular cartilage functions to absorb shock and reduce friction during movement.

Given what we know, we can confirm that the scenario that best demonstrates the mechanism of apoptosis is 1, "An immune cell Self-destructs once it is no longer needed by the immune system".
<h3>What is apoptosis?</h3>
- This is what we describe as a programmed cellular death.
- This means that when a cell is no longer needed or is damaged or old, it is programmed to automatically self-destruct in order to make room for new cells.
- This is also an effective way to reuse the resources the cell contained.
- When this mechanism fails, it can often lead to the formation of cancer.
Therefore, we can confirm that option 1 which states "An immune cell Self-destructs once it is no longer needed by the immune system" is the best description available of apoptosis given its definition as a programmed cellular death.
