1. The process by which one element changes into another through radioactive decay is known as:

• A. Transmutation
• B. Fission
• C. Fusion
• D. Oxidation

Correct answer: A

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).

2. Which of the following describes a vector quantity?

• A. Speed
• B. Distance
• C. Mass
• D. Velocity

Correct answer: d

Rationale: Velocity is a vector quantity as it includes both magnitude (speed) and direction.

3. An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?

• A. 12 milliliters
• B. 24 milliliters
• C. 60 milliliters
• D. 120 milliliters

Correct answer: B

Rationale: First convert minutes to hours (1 hour * 60 minutes). Then, multiply the number of drops per minute (40 drops/minute) by the volume per drop (0.05 ml/drop) and by the conversion factor (60 minutes/hour) to find the total volume delivered: 40 drops/minute * 0.05 ml/drop * 60 minutes/hour = 24 milliliters.

4. Cartilage is a flexible connective tissue found in the:

• A. Center of long bones
• B. Joints between bones
• C. Muscle tissue
• D. Walls of blood vessels

Correct answer: A

Rationale: Cartilage is a flexible connective tissue that is found in the joints between bones. It is a strong yet flexible tissue that cushions and supports the joints, allowing for smooth movement and reducing friction between bones. Cartilage is not typically found in the center of long bones, muscle tissue, or walls of blood vessels. Therefore, the correct answer is B: 'Joints between bones.'

5. What type of waves require a medium (solid, liquid, or gas) to propagate?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: B

Rationale: Longitudinal waves require a medium (solid, liquid, or gas) to propagate because the particles in the medium move parallel to the direction of the wave. Transverse waves, on the other hand, do not require a medium and can propagate through a vacuum. Electromagnetic waves also do not require a medium for propagation, as they consist of oscillating electric and magnetic fields. Surface waves are a combination of both longitudinal and transverse waves and also require a medium to propagate.

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.
