1. The final sentence highlights the need for

• A. Public funding for scientific research and development of climate-friendly technologies.
• B. Individual lifestyle changes and responsible consumption habits to reduce carbon footprints.
• C. International partnerships and collaborative efforts to implement effective climate action plans.
• D. Educational campaigns raising awareness about the urgency of addressing climate change.

Correct answer: C

Rationale: The emphasis on "international cooperation," "robust scientific research," and "adapting" suggests a focus on collaborative and multi-faceted solutions, aligning with C.

2. What type of intermolecular force is responsible for the high surface tension of water?

• A. Hydrogen bonding
• B. London dispersion forces
• C. Ionic bonding
• D. Metallic bonding

Correct answer: A

Rationale: The high surface tension of water is due to the strong hydrogen bonding between water molecules. Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (such as oxygen in water) and is attracted to another electronegative atom nearby. This results in a strong attraction between water molecules at the surface, leading to a high surface tension.

3. Which of the following is an example of a commensal relationship between a microorganism and a human?

• A. Salmonella causing food poisoning
• B. taphylococcus aureus causing skin infections
• C. coli living in the gut
• D. Rabies virus causing neurological disease

Correct answer: C

Rationale: Rationale: A commensal relationship is a type of symbiotic relationship in which one organism benefits, while the other is neither harmed nor benefited. In this case, E. coli living in the gut is an example of a commensal relationship because it can benefit from the environment in the gut without causing harm to the human host. Option A, Salmonella causing food poisoning, is an example of a pathogenic relationship where the microorganism causes harm to the host. Option B, Staphylococcus aureus causing skin infections, is also an example of a pathogenic relationship where the microorganism causes harm to the host. Option D, Rabies virus causing neurological disease, is another example of a pathogenic relationship where the microorganism causes harm to the host.

4. Ms. Valencia is responsible to the number of personnel reporting to her. This principle refers

• A. Span of control
• B. Unity of command
• C. Carrot and stick principle
• D. Esprit d’ corp

Correct answer: B

Rationale: The correct answer is B: Unity of command. Unity of command is a fundamental principle of management stating that each employee should receive orders from only one supervisor to avoid confusion and ensure clarity in the chain of command. In this scenario, Ms. Valencia's responsibility for the number of personnel reporting to her aligns with the concept of unity of command. Span of control refers to the number of subordinates a supervisor can efficiently manage, while the carrot and stick principle involves motivating employees through rewards and punishments. Esprit d’ corp refers to the sense of unity and camaraderie within a group.

5. Centrioles are structures involved in cell division. What is their specific role?

• A. Forming the nuclear envelope
• B. Replicating DNA
• C. Organizing microtubules during cell division
• D. Protein synthesis

Correct answer: C

Rationale: Centrioles are cylindrical structures found in animal cells that play a crucial role in organizing microtubules during cell division. They form the spindle fibers that help separate chromosomes during mitosis and meiosis. This organization is essential for the proper alignment and separation of chromosomes, ensuring accurate distribution of genetic material to daughter cells. Centrioles do not participate in forming the nuclear envelope, replicating DNA, or protein synthesis. Therefore, the correct answer is C, as centrioles are primarily involved in microtubule organization to facilitate cell division.

6. What is a potential limitation of using case studies in scientific research?

• A. They offer unique insights and perspectives not found in large-scale studies.
• B. They can be easily replicated and validated by other researchers.
• C. They often present limited data points and may not be generalizable to larger populations.
• D. They require sophisticated statistical analysis, making them difficult to interpret.

Correct answer: C

Rationale: While case studies provide valuable individual details, their small sample size and specific context limit their ability to represent broader trends or populations.
