Answer
This statement is also incorrect. While external signals can trigger apoptosis, it can also be initiated by internal signals such as DNA damage.

Answer
This statement is misleading. Apoptosis leads to the controlled death and dismantling of a cell, but it does not involve the reuse of all cell parts; rather, the process results in the breakdown of cellular components.
Step 4
D. can involve the death of perfectly healthy cells.

Answer
This statement is correct. Apoptosis can indeed result in the death of healthy cells under certain physiological or pathological conditions, such as during development or in response to stress signals.
