Answer:
D. All of the choices are correct.
Explanation:
Apoptosis, also known as programmed cell death, is a mechanism that maintains cellular and bodily integrity by eliminating potentially cancerous, damaged and virus-infected cells. Apoptosis also eliminates cells that undergo irreparable DNA damage.
Apoptosis, unlike necrosis, is the type of cell death that shrinks and packages cellular components into vesicles and transports them outside the cell, to be consumed by immune cells.
Apoptosis is a crucial process in human development. Our hands, that start out as webbed paddles, eventually separate into fingers due to apoptosis.
It occurs in all vertebrate species that have finger- or toe-like digits, and less apoptosis results in more webbing between the digits. Sometimes, if a small mistake happens during finger or toe development, apoptosis may be incomplete, leading to fused toes.
In frog development, apoptosis is responsible for the loss of the tail in tadpoles.
