1. Which organelle in the cell is responsible for producing energy in the form of ATP?

• A. Nucleus
• B. Mitochondria
• C. Ribosome
• D. Golgi apparatus

Correct answer: B

Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouses of the cell and are responsible for producing energy in the form of ATP through cellular respiration. ATP is the primary energy currency of the cell, powering various cellular activities. The nucleus (choice A) is responsible for housing the cell's genetic material but is not involved in ATP production. Ribosomes (choice C) are involved in protein synthesis, not energy production. The Golgi apparatus (choice D) is responsible for modifying, sorting, and packaging proteins for secretion, not for ATP production.

2. How much hydrochloric acid (HCl) is necessary to make 2.5 liters of a 5:1 solution of water (in liters) to HCl (in grams)?

• A. 0.5 grams
• B. 2 grams
• C. 5 grams
• D. 12.5 grams

Correct answer: C

Rationale: To create a 5:1 solution in 2.5 liters, 0.5 liters are needed for HCl, which translates to 5 grams. The correct answer is 5 grams, as this amount corresponds to the 5:1 ratio specified in the solution. Choices A, B, and D are incorrect because they do not align with the 5:1 ratio and the volume of the solution.

3. A large pizza has a diameter of 9 inches. Which of the following is the area of the pizza in terms of pi?

• A. 11.25 Ï€in²
• B. 29.57 Ï€in²
• C. 18.35 Ï€in²
• D. 20.25 Ï€in²

Correct answer: D

Rationale: To find the area of a circle, we use the formula A = πr², where r is the radius of the circle. In this case, the diameter is 9 inches, so the radius is half of the diameter, which is 4.5 inches. Substituting the radius into the formula, we get A = π(4.5)² = 20.25 πin². Therefore, the correct answer is 20.25 πin². Choices A, B, and C are incorrect because they do not correctly calculate the area using the radius of the circle.

4. Which of the following sentences uses second person point of view?

• A. I don't want to make plans for the weekend before I see my work schedule.
• B. She had to miss the last three yoga classes due to illness.
• C. Pluto is no longer considered a planet because it is not gravitationally dominant.
• D. Be sure to turn off all of the lights before locking up for the night.

Correct answer: D

Rationale: The correct answer is D. This sentence uses the second person point of view by directly addressing the reader or listener with the phrase 'Be sure to.' It is instructing or advising someone on what action to take, making it a clear example of second person point of view. Choices A, B, and C all use first person (I) or third person (she, Pluto), which do not involve direct interaction with the reader or listener, unlike the second person point of view present in choice D.

5. Which of the following sentences uses correct punctuation for a possessive noun?

• A. The baby's bibs were covered in pureed food.
• B. Sarah's and Claire's business was thriving in its new location.
• C. A multitude of clients' complaints filled the comment box.
• D. A busy worker's best tool is a good plan.

Correct answer: C

Rationale: Choice C, 'A multitude of clients' complaints filled the comment box,' is the correct answer. 'Clients'' is the plural possessive form to indicate that the complaints belong to the clients. In Choice A, 'baby's' is correctly punctuated to show the bibs belong to the baby. Choice B, 'Sarah's and Claire's business was thriving in its new location,' incorrectly uses an apostrophe before 'business,' making it possessive twice. Choice D, 'A busy worker's best tool is a good plan,' correctly shows possession of the best tool by the busy worker.
