1. What is the function of a cell wall?

• A. To provide structural support for the cell
• B. To transport substances in and out of the cell
• C. To synthesize proteins and lipids
• D. To store genetic material

Correct answer: A

Rationale: Rationale: The cell wall is a rigid layer that surrounds the cell membrane in plant cells, fungi, and some bacteria. Its main function is to provide structural support and protection for the cell, helping maintain the cell's shape and preventing it from bursting or collapsing. The cell wall also allows for the passage of water, ions, and other molecules in and out of the cell. Options B, C, and D are incorrect because those functions are typically carried out by other cellular structures such as the cell membrane, ribosomes, and nucleus, respectively.

2. The final sentence suggests that the debate surrounding UBI necessitates

• A. Focusing on the potential cost savings for governments compared to existing welfare programs.
• B. Prioritizing the opinions of economists and financial experts over those of social scientists and philosophers.
• C. Engaging in thoughtful and informed discussions considering both the economic and ethical implications.
• D. Dismissing the concerns of critics and implementing UBI as a rapid solution to poverty and inequality.

Correct answer: C

Rationale: The emphasis on "complex interplay" and "careful consideration" suggests a call for nuanced and multifaceted discussions, aligning with C.

3. What type of error occurs in the sentence "Everyone knew who the culprit was, except for me"?

• A. Subject-verb agreement
• B. Misplaced modifier
• C. Dangling participle
• D. Pronoun-antecedent agreement

Correct answer: B

Rationale: The phrase "except for me" modifies "everyone," but it is misplaced after the verb "knew," causing confusion.

4. What is the unit of measurement for force in the International System of Units (SI)?

• A. Newton (N)
• B. Kilogram (kg)
• C. Joule (J)
• D. Meter per second squared (m/s²)

Correct answer: a

Rationale: Force is measured in Newtons (N) in the SI system.

5. Which statement accurately describes cytokinesis in animal cells?

• A. Which statement accurately describes cytokinesis in animal cells?
• B. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
• C. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
• D. The nucleus elongates and pulls apart, physically dividing the cytoplasm into two.

Correct answer: B

Rationale: Rationale: A) This statement is a duplicate of option C and does not accurately describe cytokinesis in animal cells. B) In animal cells, during cytokinesis, a cleavage furrow forms in the center of the dividing cell. This furrow deepens and eventually pinches the cytoplasm into two daughter cells. This process is distinct from plant cells, where a cell plate forms. C) This statement is a duplicate of option A and does not accurately describe cytokinesis in animal cells. D) This statement describes the process of nuclear division (mitosis) rather than cytokinesis, which is the division of the cytoplasm.

6. Which process involves the body's natural defense against inhaled dust and allergens?

• A. Cellular respiration
• B. Gas exchange
• C. Ciliary action
• D. Bronchoconstriction

Correct answer: C

Rationale: The correct answer is C: Ciliary action. Cilia are tiny hair-like structures lining the respiratory tract that help trap and remove inhaled dust and allergens. When these particles are trapped in the mucus produced by the cilia, the cilia beat in a coordinated fashion to move the mucus and its trapped particles out of the respiratory system, preventing them from reaching the lungs. Cellular respiration (A) is the process by which cells generate energy from nutrients, not a defense mechanism. Gas exchange (B) refers to the exchange of oxygen and carbon dioxide in the lungs, not a defense mechanism. Bronchoconstriction (D) is the narrowing of the airways, often in response to triggers like allergens, but it is not the body's natural defense mechanism against inhaled dust and allergens.
