1. What is the process of cells dividing to produce new cells called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

2. Which of the following is NOT a part of the body's innate immune response?

• A. Physical barriers like skin and mucous membranes
• B. Phagocytes that engulf and destroy pathogens
• C. Inflammatory response to isolate and contain infection
• D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The correct answer is D. The body's innate immune response is the first line of defense against pathogens, and it includes physical barriers like skin and mucous membranes (option A), phagocytes that engulf and destroy pathogens (option B), and the inflammatory response to isolate and contain infections (option C). The production of antibodies specific to a particular pathogen (option D) is part of the adaptive immune response, which develops over time and is not considered part of the innate immune system. Therefore, option D is not a component of the body's innate immune response.

3. In a chemical reaction, the total amount of:

• A. Matter remains the same
• B. Matter increases
• C. Matter decreases
• D. Energy remains the same

Correct answer: A

Rationale: The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged

4. A person who carries a pathogen but does not exhibit any symptoms is considered:

• A. Asymptomatic carrier
• B. Opportunistic pathogen
• C. Nosocomial infection
• D. Vector-borne disease

Correct answer: A

Rationale: Rationale: An asymptomatic carrier is a person who carries a pathogen (such as a virus or bacterium) but does not show any symptoms of the infection themselves. Despite not exhibiting symptoms, asymptomatic carriers can still spread the pathogen to others, potentially causing illness in those who come into contact with them. This term specifically refers to individuals who are infected but do not develop symptoms, distinguishing them from symptomatic carriers who do show signs of the infection. Option A is the most appropriate choice in this context as it accurately describes a person who carries a pathogen without displaying symptoms. B) Opportunistic pathogen: This term refers to pathogens that typically do not cause disease in healthy individuals but can become pathogenic in individuals with weakened immune systems. C) Nosocomial infection: This term refers to infections that are acquired in a hospital or healthcare facility. D) Vector-borne disease: This term refers to diseases

5. A ball is thrown horizontally off a cliff. Which of the following forces is responsible for its downward motion?

• A. The force of throwing
• B. Normal force from the air
• C. Tension force from the string (if used)
• D. Gravitational force

Correct answer: D

Rationale: The gravitational force is responsible for the downward motion of the ball. When the ball is thrown horizontally off a cliff, the only force acting on it in the vertical direction is the force of gravity, which pulls the ball downward towards the ground. The other forces mentioned (force of throwing, normal force from the air, tension force from the string) do not contribute to the ball's downward motion in this scenario.

6. A ball is thrown horizontally off a cliff with a speed of 10 m/s. What is the horizontal distance the ball travels before hitting the ground?

• A. 10 m
• B. 20m
• C. 30m
• D. Cannot be determined without knowing the height of the cliff

Correct answer: C

Rationale: When a ball is thrown horizontally, its horizontal velocity remains constant throughout its motion. The time taken to hit the ground is determined by the vertical motion, which is independent of the horizontal velocity. Therefore, the horizontal distance traveled by the ball is determined by the horizontal velocity and the time taken to hit the ground. In this case, the horizontal distance is calculated as distance = velocity × time = 10 m/s × time. Since the horizontal velocity is 10 m/s and the time taken to hit the ground is determined by the vertical motion, the horizontal distance traveled by the ball is 10 m/s × time. Without knowing the height of the cliff, we can still determine the horizontal distance traveled by the ball, which is 10 m/s × time.
