1. Which type of wave requires a medium to travel through?

• A. Electromagnetic waves
• B. Mechanical waves
• C. Sound waves
• D. Both A and C

Correct answer: B

Rationale: Mechanical waves, unlike electromagnetic waves, require a medium (such as air, water, or solids) to propagate. Sound waves are a specific type of mechanical wave that necessitates a medium, like air or water, for transmission. Electromagnetic waves, on the other hand, can travel through a vacuum as they do not rely on a medium for propagation. Choice A (Electromagnetic waves) is incorrect since they do not require a medium to travel. Choice C (Sound waves) is partially correct in that it is a type of mechanical wave that needs a medium but is not the only type. Choice D (Both A and C) is incorrect because electromagnetic waves do not require a medium, only mechanical waves like sound waves do.

2. A couple dining at a restaurant receives a bill for $28.40. They wish to leave a 10% tip. Which of the following is the estimated gratuity?

• A. $4.00
• B. $6.00
• C. $2.50
• D. $3.00

Correct answer: D

Rationale: To calculate a 10% tip on a bill of $28.40, you would first find 10% of $28.40, which is $2.84. Since you typically round up when leaving a tip, the estimated gratuity would be $3.00. Option A is incorrect as it is too high for a 10% tip. Option B is incorrect as it is too high. Option C is incorrect as it is too low for a 10% tip. Therefore, the correct answer is $3.00.

3. How does Wilde use irony to critique the upper class in the play?

• A. By portraying the upper class as sincere and honorable.
• B. By showing that the upper class is deeply concerned with morality.
• C. By exaggerating the trivial concerns and behaviors of the upper class.
• D. By highlighting the noble and upright nature of the upper class.

Correct answer: C

Rationale: Wilde uses irony by exaggerating the trivial concerns and behaviors of the upper class, revealing their lack of genuine depth and morality. In 'The Importance of Being Earnest,' Wilde satirizes the British aristocracy by highlighting their absurdities and trivialities. The play's characters, like Jack Worthing and Algernon Moncrieff, lead double lives, symbolizing the dual nature of their social status. Through witty dialogue, puns, and irony, Wilde exposes the superficiality and hypocrisy of the upper classes. The term 'Bunburying' coined by Wilde exemplifies the characters' deceitful actions to avoid social responsibilities. Additionally, the play ridicules the concept of marriage, portraying it as a societal transaction rather than a romantic bond. For instance, Lady Bracknell's interrogation of Jack about his eligibility as a suitor for Gwendolen underscores the materialistic view of marriage prevalent in the society Wilde critiques. Wilde's humorous yet critical portrayal of the aristocracy in 'The Importance of Being Earnest' makes it a timeless and cherished work.

4. Where in the cell are proteins modified, sorted, and packaged for transport?

• A. Ribosomes
• B. Golgi apparatus
• C. Endoplasmic reticulum (ER)
• D. Lysosomes

Correct answer: B

Rationale: The Golgi apparatus is the cellular organelle responsible for modifying, sorting, and packaging proteins for transport within the cell or for secretion outside the cell. Ribosomes are not involved in modifying, sorting, or packaging proteins; they are responsible for protein synthesis. The endoplasmic reticulum (ER) is primarily involved in protein synthesis and folding, rather than modification and packaging for transport. Lysosomes function in breaking down cellular waste rather than modifying, sorting, or packaging proteins for transport.

5. With which genotype would the recessive phenotype appear if the dominant allele is marked with 'A' and the recessive allele is marked with 'a'?

• A. AA
• B. aa
• C. Aa
• D. aA

Correct answer: B

Rationale: The recessive phenotype appears when an individual has two copies of the recessive allele. In this case, the recessive allele is marked with 'a.' Therefore, the genotype 'aa' would display the recessive phenotype as both alleles are recessive. Choice A (AA) has two dominant alleles, choice C (Aa) has one dominant and one recessive allele, and choice D (aA) represents the same genotype as Aa due to the principle of allele dominance.
