1. Which pronoun correctly replaces the phrase Sarah and me in the sentence: 'Jessica invited Sarah and me to the party, but I forgot to respond to her.'

A. We
B. Us
C. Ours
D. Myself

Correct answer: B

Rationale: The correct answer is 'B: Us.' In the sentence, 'Jessica invited Sarah and me to the party,' 'Sarah and me' serve as the object of the verb 'invited.' Therefore, the pronoun 'us' is the correct choice to replace 'Sarah and me' as the object pronoun. Choice A, 'We,' is a subject pronoun and does not fit in this context. Choice C, 'Ours,' is a possessive pronoun and is not appropriate for replacing the object pronoun 'Sarah and me.' Choice D, 'Myself,' is a reflexive pronoun, which is not suitable for this sentence where an object pronoun is needed.

2. According to the aforementioned passage, what is the speaker's second desire for his time in front of the audience?

A. To read a Christmas story
B. For the working man to have a say in the management of the institution designed for his benefit
C. To have an opportunity to stand in their presence
D. For the life of the institution to be essential to the audience as a whole

Correct answer: B

Rationale: The correct answer is B. The speaker's second desire for his time in front of the audience is for the working man to have a say in the management of the institution designed for his benefit. This is evident from the passage where the speaker emphasizes the importance of the working man having a share in the management of an institution designed for his benefit. Choice A is incorrect because although reading a Christmas story was mentioned as the first desire, it was not the second desire. Choice C is incorrect as the desire mentioned is not about standing in the audience's presence but rather about the working man having a say in the institution. Choice D is incorrect as it does not align with the speaker's second desire as mentioned in the passage.

3. What is the molar mass of Ca(NO3)2?

A. 74.1 g/mol
B. 132.1 g/mol
C. 164.1 g/mol
D. 78.1 g/mol

Correct answer: B

Rationale: To calculate the molar mass of Ca(NO3)2, we add up the individual atomic masses of its elements: Ca (40.08) + 2N (2 * 14.01) + 6O (6 * 16.00) = 40.08 + 28.02 + 96.00 = 164.1 g/mol. Therefore, the correct answer is 164.1 g/mol (Choice C). Choice A (74.1 g/mol) is incorrect as it does not account for the correct sum of atomic masses. Choice B (132.1 g/mol) is the correct molar mass calculation for Ca(NO3)2. Choice D (78.1 g/mol) is incorrect and does not reflect the accurate molar mass of the compound.

4. Which of the following is LEAST likely to be found in a human cell's genes?

A. Sequences of amino acids to be transcribed into mRNA
B. Lethal recessive traits like sickle cell anemia
C. Mutated DNA
D. DNA that codes for proteins the cell doesn't use

Correct answer: D

Rationale: Human cells typically contain genes that code for proteins necessary for the cell's functions. DNA that codes for proteins the cell doesn't use would be an inefficient use of the cell's resources. Therefore, it is less likely to be found in a human cell's genes. Options A, B, and C are more commonly associated with genes found in human cells. Choice A refers to the genetic information needed for protein synthesis, while choice B involves traits that can be present in the gene pool. Mutated DNA (choice C) can also be found in human cells as a result of genetic alterations. However, DNA that codes for proteins not utilized by the cell would be redundant and not typically retained in the genome.

5. Which organelle is responsible for packaging and secreting proteins into the extracellular space?

A. Golgi apparatus
B. Mitochondria
C. Ribosomes
D. Endoplasmic reticulum

Correct answer: A

Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion outside the cell or for use within the cell. It acts as a distribution and shipping department for the cell, ensuring proteins are properly processed and sent to their correct destinations like the extracellular space. Golgi apparatus is the correct answer because it directly handles the packaging and secretion of proteins. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in packaging and secreting proteins into the extracellular space. C) Ribosomes: Ribosomes are responsible for protein synthesis, where they translate mRNA into proteins. They are not involved in packaging and secreting proteins into the extracellular space. D) Endoplasmic reticulum: The endoplasmic reticulum (ER) plays a role in protein synthesis and folding, but it is the rough ER specifically that is involved in synthesizing proteins that are then transported to the Golgi apparatus for further processing and packaging. The Golgi apparatus is primarily responsible for packaging and secreting proteins, making it the correct answer for this question.
