• A. of
• B. from
• C. on
• D. for

Correct answer: B

Rationale: "From" indicates the source of the borrowed money.

2. What is the relationship between the frequency and period of a wave?

• A. They are unrelated
• B. Frequency = Period
• C. Frequency = 1/Period
• D. Period = 1/Frequency

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This means that the period of a wave is the reciprocal of its frequency. Frequency is the number of complete cycles of a wave that occur in a unit of time, while the period is the time it takes for one complete cycle of the wave to occur. Since frequency and period are inversely related, the correct formula is Period = 1/Frequency.

3. What term describes the bouncing back of waves after striking a surface or boundary?

• A. Diffraction
• B. Refraction
• C. Reflection
• D. Interference

Correct answer: c

Rationale: Reflection occurs when waves bounce back after hitting a surface or boundary.

• A. Viscosity
• B. Ductility
• C. Malleability
• D. Conductivity

Correct answer: c

Rationale: Malleability refers to the resistance of a substance to being hammered or pressed into different shapes without breaking.

5. What property of a substance refers to its ability to be drawn into thin wires?

• A. Conductivity
• B. Ductility
• C. Viscosity
• D. Malleability

Correct answer: b

Rationale: Ductility refers to a substance's ability to be drawn into thin wires without breaking.

6. The structural and functional unit of the kidney responsible for filtering blood is the:

• A. Nephron
• B. Ureter
• C. Urethra
• D. Bladder

Correct answer: A

Rationale: The correct answer is A, Nephron. The nephron is the structural and functional unit of the kidney responsible for filtering blood. It consists of the glomerulus, renal tubule, and collecting duct. The nephron's filtration process plays a crucial role in removing waste products, regulating electrolyte balance, and maintaining blood pressure. The other options, B: Ureter, C: Urethra, and D: Bladder, are not responsible for filtering blood. The ureter transports urine from the kidneys to the bladder, the urethra is responsible for urine excretion from the bladder, and the bladder stores urine before excretion. Therefore, the nephron is specifically designed for the filtration process within the kidney.
