Give examples of what could trigger apoptosis.

Explanation:

Apoptosis is a kind of programmed death of cells. It typically occurs in the multicellular organisms. These includes the cell shrinkage, chromatin condensation, mRNA decay, chromosomal DNA fragmentation and cell shrinkage. The average human adult can loose 50-70 billion cells per day due to apoptosis. For children between the age group of 8-14 years approximately 20-30 billion cells die each day.

The enzyme caspases can trigger apoptosis by cleaving the specific proteins in the nucleus and cytoplasm. This enzyme exists in cells as a inactive precursor.

A viral infection can also trigger the apoptosis this happens when one or many cells of a living being are infected by the virus leading to the cell death.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
