question 6
apoptosis is...

a disorder in humans that results in abnormal growth of cells.

a disorder in rats that causes their cells to pop under certain environmental conditions.

a process whereby cells are triggered to go through cellular division.

pre - programmed cell death.

pre - programmed cell death of new healthly cells.

Explanation:

Apoptosis is a biological process. It is a form of programmed cell death. This process is important for normal development (such as shaping body structures during embryonic development) and for maintaining tissue homeostasis (removing old or damaged cells). Let's analyze each option:

• "a disorder in humans that results in abnormal growth of cells": Abnormal cell growth is more related to cancer (uncontrolled cell proliferation) rather than apoptosis.
• "a disorder in rats that causes their cells to pop under certain environmental conditions": This is an incorrect and rather a made - up description. Apoptosis is a normal biological process in many organisms (not just rats) and is not a disorder in the sense described.
• "a process whereby cells are triggered to go through cellular division": Cellular division is mitosis or meiosis. Apoptosis is the opposite (cell death, not division).
• "pre - programmed cell death": This is the correct general definition of apoptosis.
• "pre - programmed cell death of new healthily cells": Apoptosis can occur in cells that are not necessarily "new". It can occur in cells that are damaged, old, or in the wrong location during development.

Answer:

pre - programmed cell death.
