1. Which term describes the resistance of a substance to being hammered into different shapes?

• A. Viscosity
• B. Ductility
• C. Malleability
• D. Conductivity

Correct answer: c

Rationale: Malleability refers to the resistance of a substance to being hammered or pressed into different shapes without breaking.

2. Which word completes the sentence: "Despite the storm, the concert ____ went on."

• A. nevertheless
• B. however
• C. therefore
• D. nonetheless

Correct answer: D

Rationale: "Nonetheless" emphasizes the continuation of the concert despite the contrary circumstance.

3. A car skids on a wet road. What is the main force preventing the car from stopping?

• A. Friction
• B. Gravitational force
• C. Normal force from the road
• D. Air resistance

Correct answer: A

Rationale: Friction opposes the motion of the car, trying to bring it to a stop. However, due to the wet surface, the friction force is not enough to overcome the car's inertia.

4. Which of the following phases of the cell cycle is characterized by the replication of DNA?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. Cytokinesis

Correct answer: A

Rationale: Rationale: Interphase is the phase of the cell cycle where the cell spends the majority of its time and is characterized by three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During the S phase of interphase, DNA replication occurs, leading to the duplication of the genetic material in the cell. This ensures that each daughter cell produced during cell division receives a complete set of genetic information. Mitosis is the phase of the cell cycle where the replicated DNA is divided equally between two daughter cells, while meiosis is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes. Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two separate daughter cells.

5. The peripheral nervous system can be further divided into which two main parts?

• A. Sensory and motor
• B. Sympathetic and parasympathetic
• C. Myelinated and unmyelinated
• D. Central and peripheral

Correct answer: A

Rationale: The correct answer is A: 'Sensory and motor.' The peripheral nervous system is divided into two main parts based on their functions. The sensory division (afferent) transmits sensory information from receptors to the central nervous system, while the motor division (efferent) transmits signals from the central nervous system to muscles and glands to produce a response. Options B, C, and D are incorrect as they do not accurately describe the main divisions of the peripheral nervous system. Understanding this division is crucial in comprehending how information is processed and responses are generated in the body.

6. How does polarization affect the intensity of light passing through a polarizing filter?

• A. All light passes through regardless of polarization.
• B. Light with the same polarization as the filter passes through, while others are blocked
• C. Light with higher intensity passes through, while weaker light is blocked.
• D. The intensity is reduced for all light, regardless of polarization.

Correct answer: B

Rationale: A polarizing filter only allows light waves with a specific polarization direction to pass through, reducing the intensity of waves with different orientations.
