1. What is the scientific term for a broken bone?

A. Osteoporosis
B. Fracture
C. Sprain
D. Dislocation

Correct answer: B

Rationale: The correct answer is B: 'Fracture.' A fracture is the scientific term used to describe a broken bone. Osteoporosis (A) is a condition where bones become weak and brittle, increasing the risk of fractures. A sprain (C) is an injury to a ligament, not a bone. A dislocation (D) occurs when the bones in a joint are forced out of their normal position, but it is not the term for a broken bone.

2. She decides to illustrate the organizational structure. Which of the following elements is

A. Level of authority
B. Lines of communication
C. Span of control
D. Unity of direction

Correct answer: D

Rationale: The correct answer is D, 'Unity of direction.' In the context of illustrating organizational structure, unity of direction refers to the concept that activities within an organization should be directed towards a common goal. It ensures that all efforts are aligned and coordinated towards achieving the organization's objectives. This element helps in avoiding conflicts and confusion by providing clarity and focus on the overall mission of the organization, which is essential for effective organizational performance. Level of authority, lines of communication, and span of control are important elements in organizational structure as well, but in this scenario, unity of direction specifically pertains to the coordination and alignment of activities towards a common purpose.

3. What is the unit of force in the SI system?

A. Newton (N)
B. Kilogram (kg)
C. Meter (m)
D. Second (s)

Correct answer: A

Rationale: Force is measured in Newtons, named after Isaac Newton who formulated the laws of motion.

4. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

A. 825 sq cm
B. 1075 sq cm
C. 1325 sq cm
D. 1575 sq cm

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.

5. 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

6. What is the process by which the body reabsorbs water from the large intestine?

A. Dehydration
B. Osmosis
C. Filtration
D. Secretion

Correct answer: B

Rationale: Rationale: - Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. - Osmosis (Option B) is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. - Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components. It is not the primary mechanism for water reabsorption in the large intestine. - Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine. Therefore, the correct process by which the body reabsorbs water from the large intestine is
