, 1. Multiple-Choice:
- Question : Which phase of the cell cycle is primarily
responsible for the replication of DNA?
- A) G1 Phase
- B) S Phase
- C) G2 Phase
- D) M Phase
- Correct Answer : B) S Phase
- Rationale : The S phase (Synthesis phase) is when DNA
replication occurs, resulting in the duplication of
chromosomes.
2. Multiple-Select:
- Question : Which of the following are true statements

- C) Mitochondria are involved in the process of apoptosis.
- D) They are the only organelle responsible for detoxifying
drugs.
- Correct Answers : B) They contain their own DNA,
which is similar to bacterial DNA. C) Mitochondria are

totaling 46 chromosomes in each diploid cell.
4. Hot Spot (Click on the Structure):
- Question : Identify the Golgi apparatus in the provided
cell diagram.
- Correct Answer : (Hotspot on Golgi Apparatus)
- Rationale : The Golgi apparatus can be identified by its
stack of membrane-bound sacs which are involved in
modifying, sorting, and packaging proteins for secretion.
5. Ordered Response:
- Question : Arrange the following steps of cellular
respiration in the correct order.
- A) Krebs Cycle
- B) Glycolysis
- C) Electron Transport Chain
- Correct Order : B) Glycolysis, A) Krebs Cycle, C)
Electron Transport Chain
- Rationale : Cellular respiration begins with Glycolysis,
followed by the Krebs Cycle, and concludes with the
Electron Transport Chain.
