1. Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?

• A. Quantitative data is collected through numerical measurements.
• B. Quantitative data is more accurate than qualitative data.
• C. Qualitative data is focused on perspectives and behavior.
• D. Qualitative data is collected through observation and interviews.

Correct answer: B

Rationale: The correct answer is B because quantitative data is not inherently more accurate than qualitative data. Both types of data have their strengths and limitations, and the choice of data type depends on the research question and methodology. Quantitative data is collected through numerical measurements and involves statistical analysis. On the other hand, qualitative data focuses on perspectives, behaviors, and meanings and is typically gathered through observation and interviews. While quantitative data provides numerical precision, qualitative data offers in-depth insights into behaviors and perspectives that cannot be quantified, making them equally valuable in scientific research.

2. What is the formula to calculate work?

• A. Work = Force × Distance
• B. Work = Mass × Velocity
• C. Work = Power × Time
• D. Work = Energy ÷ Time

Correct answer: A

Rationale: Work is defined as the product of the force applied to an object and the distance over which the force is applied. The formula to calculate work is represented by Work = Force × Distance, where force is the applied force on an object and distance is the displacement over which the force is applied. Therefore, the correct formula to calculate work is Work = Force × Distance. Choice B, 'Work = Mass × Velocity,' is incorrect because work involves force and distance, not mass and velocity. Choice C, 'Work = Power × Time,' is incorrect because work is not directly calculated using power and time. Choice D, 'Work = Energy ÷ Time,' is incorrect because work is not typically calculated by dividing energy by time; rather, it involves the product of force and distance.

3. What is the process of converting lactic acid back into pyruvate called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Cori cycle
• D. Oxidative phosphorylation

Correct answer: C

Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.

4. What is the final phase of mitosis?

• A. Prophase
• B. Telophase
• C. Anaphase
• D. Metaphase

Correct answer: B

Rationale: Telophase is indeed the final phase of mitosis. During telophase, the chromosomes have reached opposite poles of the cell, the nuclear envelope is re-forming around the separated sister chromatids, and cytokinesis may also occur, leading to the division of the cell into two daughter cells. Choice A, Prophase, is incorrect as it is the initial phase of mitosis where chromatin condenses into chromosomes. Choice C, Anaphase, is incorrect as it is the phase where sister chromatids separate and move towards opposite poles. Choice D, Metaphase, is incorrect as it is the phase where chromosomes align at the cell's equator before separating.

5. How is the muscular system benefited by regular exercise?

• A. Decreasing muscle mass
• B. Improving muscle strength and endurance
• C. Making muscles less flexible
• D. Increasing the risk of muscle tears

Correct answer: B

Rationale: Regular exercise is beneficial for the muscular system by improving muscle strength and endurance. Exercise helps to build and maintain muscle mass, increase muscle strength, and enhance muscle endurance. It does not decrease muscle mass, make muscles less flexible, or increase the risk of muscle tears when done properly. Therefore, the correct answer is improving muscle strength and endurance, as it aligns with the positive effects of regular exercise on the muscular system.
