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. Balance the following redox reaction in acidic solution: I⁻ (aq) + Cr₂O₇²⁻ (aq) -> I₂ (aq) + Cr³⁺ (aq). Identify the oxidizing agent and reducing agent.

• A. I⁻ is oxidized, Crâ‚‚O₇²⁻ is reduced
• B. I⁻ is reduced, Crâ‚‚O₇²⁻ is oxidized.
• C. Both I⁻ and Crâ‚‚O₇²⁻ are oxidized.
• D. Both I⁻ and Crâ‚‚O₇²⁻ are reduced.

Correct answer: A

Rationale: . I⁻ loses an electron (oxidation), Cr₂O₇²⁻ gains electrons (reduction).

3. What is the relationship between force and acceleration according to Newton's second law?

• A. Force is directly proportional to acceleration
• B. orce is inversely proportional to acceleration
• C. Force has no relation to acceleration
• D. Force causes deceleration, not acceleration

Correct answer: A

Rationale: According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is mathematically expressed as F = ma, where F represents force, m represents mass, and a represents acceleration. Therefore, an increase in force will result in a proportional increase in acceleration, supporting the statement that force is directly proportional to acceleration.

4. Julius plans to revisit the organizational chart of the department. He plans to create a new

• A. Box
• B. Solid line
• C. Broken line
• D. Dotted line

Correct answer: B

Rationale: The correct answer is B: 'Solid line.' In organizational charts, solid lines typically represent formal reporting relationships, indicating direct authority and responsibility between positions. Creating a new solid line on the chart would signify a new formal reporting relationship within the department. This can be important for clarifying roles, communication channels, and decision-making processes. Boxes represent positions or roles in the organizational structure, while broken lines and dotted lines are typically used for informal relationships or advisory roles, rather than formal reporting relationships.

5. The ball-and-socket joint, which allows for wide range of motion, is found in the connection between:

• A. Upper arm and shoulder blade (scapula)
• B. Collarbone (clavicle) and breastbone (sternum)
• C. Two vertebrae in the spine
• D. Ribs and sternum

Correct answer: A

Rationale: The correct answer is A: 'Upper arm and shoulder blade (scapula).' The ball-and-socket joint is found in the connection between the humerus (upper arm bone) and the scapula (shoulder blade). This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. The collarbone (clavicle) and breastbone (sternum) are connected by a cartilaginous joint, not a ball-and-socket joint. Two vertebrae in the spine are connected by facet joints, and the ribs and sternum are connected by cartilaginous joints and the costovertebral joints. Therefore, the ball-and-socket joint is uniquely found in the connection between the upper arm and the shoulder blade, allowing for the shoulder's impressive range of motion.

6. Which of the following is the primary function of the cell membrane?

• 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: B

Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.
