1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

• A. Her eyes glistened in the moonlight, with tears.
• B. Tears glistened in her eyes with moonlight.
• C. Her eyes, in the moonlight, glistened with tears.
• D. Tears made her eyes glisten in the moonlight.

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

3. What is the process by which a population gradually loses genetic variation?

• A. Founder effect
• B. Bottleneck effect
• C. Gene flow
• D. Speciation

Correct answer: B

Rationale: Rationale: A) Founder effect: This occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not necessarily result in a gradual loss of genetic variation in an existing population. B) Bottleneck effect: This process occurs when a population is drastically reduced in size, leading to a significant loss of genetic variation due to the limited number of individuals contributing to the gene pool. The reduced genetic diversity can have long-term effects on the population's ability to adapt to environmental changes. C) Gene flow: This refers to the movement of genes between populations, which can introduce new genetic variation and prevent populations from diverging. Gene flow does not lead to a gradual loss of genetic variation within a population. D) Speciation: This is the process by which new species evolve from existing species, often involving the accumulation of genetic differences that l

4. Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Smooth muscle. Smooth muscle tissue contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, and cardiac muscle is specific to the heart. Therefore, smooth muscle is the only type of muscle tissue that fits the description provided in the question, making it the correct choice. Option D, 'All of the above,' is incorrect as it includes skeletal and cardiac muscles, which do not fit the criteria of being found in organs like the heart and intestines. Understanding the differences between these types of muscle tissue is crucial for comprehending their specific functions in the body.

5. Which of the following is an example of an unsaturated fatty acid?

• A. Stearic acid
• B. Palmitic acid
• C. Oleic acid
• D. Butyric acid

Correct answer: C

Rationale: Oleic acid is an unsaturated fatty acid, containing at least one double bond in its hydrocarbon chain. The other choices are saturated fatty acids.

6. She notes that there is an increasing unrest of the staff due to fatigue brought about by

• A. Evaluate the overall result of the unrest
• B. Initiate a group interaction
• C. Develop a plan and implement it
• D. Identify external and internal forces.

Correct answer: C

Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.
