• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The kidneys are the primary organs responsible for filtering blood and removing waste products, excess fluids, and toxins. They play a crucial role in maintaining the body's internal environment and regulating blood pressure.

2. What is the term for the number of moles of solute per liter of solution?

• A. Molarity
• B. Molality
• C. Normality
• D. Concentration

Correct answer: A

Rationale: Molarity is defined as the number of moles of solute per liter of solution. The other choices are different concentration units.

3. What is the main idea of the passage?

• A. Petra is a modern city built for tourism.
• B. Petra's historical significance lies in its architectural achievements.
• C. Petra's prosperity was linked to its strategic location on trade routes.
• D. Petra's obscurity remains a mystery despite its rediscovery.

Correct answer: C

Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.

4. What is the term for an organism with two different alleles for a gene?

• A. Homozygous
• B. Heterozygous
• C. Dominant
• D. Recessive

Correct answer: B

Rationale: An organism with two different alleles for a gene has a mixed genotype and may exhibit either the dominant or recessive trait depending on the specific gene and its alleles.

5. Which type of waves do not require a medium for propagation?

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

Correct answer: c

Rationale: Electromagnetic waves (such as light or radio waves) can travel through a vacuum as they do not require a medium.

6. Relatively prime numbers share no common factors other than 1. Which of the following pairs of numbers are relatively prime?

• A. 12 and 16
• B. 15 and 17
• C. 20 and 24
• D. 28 and 36

Correct answer: B

Rationale: Rationale: - Relatively prime numbers are numbers that share no common factors other than 1. - To determine if two numbers are relatively prime, we need to find the greatest common divisor (GCD) of the two numbers. If the GCD is 1, then the numbers are relatively prime. - Let's calculate the GCD for each pair of numbers: A) GCD(12, 16) = 4, not relatively prime B) GCD(15, 17) = 1, relatively prime C) GCD(20, 24) = 4, not relatively prime D) GCD(28, 36) = 4, not relatively prime Therefore, the pair of numbers 15 and 17 are relatively prime because their greatest common divisor is 1, meaning they share no common factors other than 1.
