Introduction:
The cell is the basic unit of life and the series of events that takes place in a living cell during its life is known as the cell cycle. The cell cycle starts when a cell is formed after mitotic division and ends when the cell is divided into two to produce daughter cells. In case, the cell or its component is damaged, the cell cycle is halted and is labeled for programmed cell death.
Answer to Problem 34A
Correct answer:
The correct answer is option (b).
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) programmed cell death. The apoptosis is the name of programmed cell death that occurs when the cells or its components are damaged. Hence, it is a correct answer.
Explanation for the incorrect answer:
Option (a) occurs in all cells. Apoptosis occurs in the cells that are damaged. Hence, it is an incorrect answer.
Option (c) disrupts the normal development of an organism. The apoptosis maintains the equilibrium of the cells and remove abnormal cells. Hence, it is an incorrect answer.
Option (d) is a response to hormone. The apoptosis is triggered by cell’s internal signaling factors not hormones. Hence, itis an incorrect answer.
