Chemistry
1. What is the term for the chemical reaction that involves the loss of electrons?
- A. Reduction
- B. Oxidation
- C. Neutralization
- D. Precipitation
Correct answer: b
Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.
2. What is the largest lymphatic vessel in the body?
- A. Jugular vein
- B. Thoracic duct
- C. Subclavian vein
- D. Aorta
Correct answer: B
Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body, responsible for draining lymph from the lower half of the body, the left side of the head and neck, and the left arm. The jugular vein (A) and subclavian vein (C) are both blood vessels, not lymphatic vessels. The aorta (D) is the largest artery in the body, responsible for carrying oxygenated blood away from the heart. Understanding the anatomy of the lymphatic system is crucial for understanding the circulation and immune functions of the body.
3. Which of the following conclusions of Ms. Castro about leadership characteristics is TRUE?
- A. There is a high correlation between the communication skills of a leader and the ability to get
- B. A manager is effective when he has the ability to plan well.
- C. Assessment of personal traits is a reliable tool for predicting a manager’s potential.
- D. There is good evidence that certain personal qualities favor success in managerial role.
Correct answer: A
Rationale: The correct answer is A because effective communication skills are essential for a leader to successfully convey ideas, motivate teams, and build relationships. Strong communication skills enable a leader to articulate goals clearly, listen to feedback, and resolve conflicts efficiently. This correlation between communication skills and leadership effectiveness has been well-documented in numerous studies. In contrast, options B, C, and D are not universally true statements about leadership characteristics. While planning skills and personal traits may contribute to effective leadership, they are not as directly linked to leadership success as communication skills. Therefore, option A is the most accurate conclusion about leadership characteristics among the choices provided.
4. Which phrase best describes the tone of the passage?
- A. Humorous and lighthearted
- B. Suspenseful and mysterious
- C. Objective and informative
- D. Critical and judgmental
Correct answer: C

5. The element responsible for the green color of leaves is:
- A. Magnesium
- B. Iron
- C. Copper
- D. Zinc
Correct answer: A
Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis
6. What are the key differences between cytokinesis in plant and animal cells?
- A. Animal cells utilize an actomyosin ring for cleavage furrow formation, while plant cells lack this mechanism.
- B. Plant cells rely on the assembly of a cell plate in the center of the dividing cell, ultimately separating the cytoplasm.
- C. Cytokinesis in both plant and animal cells is driven by the expansion of the endoplasmic reticulum.
- D. Both types of cells achieve cytokinesis through similar membrane pinching and constriction mechanisms.
Correct answer: B
Rationale: Rationale: A) Animal cells utilize an actomyosin ring for cleavage furrow formation, while plant cells lack this mechanism. - This statement is true. Animal cells use an actomyosin ring to form a cleavage furrow during cytokinesis, while plant cells do not have this mechanism. Instead, plant cells form a cell plate. B) Plant cells rely on the assembly of a cell plate in the center of the dividing cell, ultimately separating the cytoplasm. - This statement is correct. Plant cells form a cell plate in the middle of the dividing cell during cytokinesis. The cell plate eventually develops into a new cell wall that separates the two daughter cells. C) Cytokinesis in both plant and animal cells is driven by the expansion of the endoplasmic reticulum. - This
