Final answer:
Apoptosis is the technique that promotes autolysis in the spontaneous separation of necrotic tissue. Lysosomes release digestive enzymes into the cytoplasm of damaged cells, causing controlled self-destruct through autolysis.
Step-by-step explanation:
The technique that promotes autolysis in the spontaneous separation of necrotic tissue is apoptosis. Autolysis is the breakdown of cells by their own enzymatic action. In the case of damaged or unhealthy cells, lysosomes can release their digestive enzymes into the cytoplasm, causing the cell to undergo controlled self-destruct. This process is known as autolysis or apoptosis. Autolysis helps in removing necrotic tissue from the body.
