1. Which sentence uses strong verbs to create a more vivid image?

• A. The car moved slowly down the street.
• B. The car drove sluggishly down the road.
• C. The car inched down the avenue.
• D. The car traveled down the thoroughfare.

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."

2. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.

3. 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

4. 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.

5. What is the main verb tense in the following sentence? "She had already left before I arrived."

• A. Present tense
• B. Past tense
• C. Future tense
• D. t perfect tense

Correct answer: D

Rationale: The verb "had left" is in the past perfect tense, indicating an action completed before another past action ("arrived").

6. Simple columnar epithelium lining the small intestine is crucial for:

• A. Movement
• B. Support
• C. Absorption
• D. Insulation

Correct answer: C

Rationale: The correct answer is C: Absorption. The simple columnar epithelium lining the small intestine is crucial for absorption due to its structure and function. It has microvilli that increase the surface area available for nutrient absorption. This epithelium also contains specialized cells like goblet cells that secrete mucus to protect the lining and aid in the movement of materials. Movement (choice A) is more related to muscle tissue rather than epithelial tissue. Support (choice B) is usually provided by connective tissue rather than epithelial tissue. Insulation (choice D) is not a function of the simple columnar epithelium in the small intestine.
