1. Protestors filled the streets of the city because they were dissatisfied with the government’s leadership. Which of the following is an appropriately-punctuated correction for this sentence?

• A. Protestors filled the streets of the city, because they were dissatisfied with the government’s leadership.
• B. Protesters, filled the streets of the city, because they were dissatisfied with the government’s leadership.
• C. Because they were dissatisfied with the government’s leadership, protestors filled the streets of the city.
• D. Protestors filled the streets of the city because they were dissatisfied with the government’s leadership.

Correct answer: D

Rationale: The correct answer is D. The sentence should be corrected by removing the period and joining the clauses to avoid a sentence fragment. Option A is incorrect because it incorrectly separates the clauses with a comma. Option B is incorrect as it incorrectly uses a comma after 'Protesters' and lacks proper structure. Option C is incorrect as it places the subordinate clause at the beginning, which disrupts the flow of the sentence.

2. What substance is required to drive the sliding filament process during muscle contraction?

• A. ATP
• B. Hormone
• C. Potassium
• D. Water

Correct answer: A

Rationale: The substance required to drive the sliding filament process during muscle contraction is ATP (adenosine triphosphate). ATP provides the energy needed for muscle contraction by enabling the myosin heads to bind to actin and generate force. This energy release drives the sliding of the filaments, causing muscle fibers to contract. Hormones, potassium, and water do not directly drive the sliding filament process in muscle contraction. Hormones are signaling molecules that regulate various physiological processes but do not directly provide energy for muscle contraction. Potassium is an electrolyte important for nerve and muscle function but is not the primary driver of the sliding filament process. Water is essential for overall hydration and bodily functions but does not directly participate in the muscle contraction process.

3. The kidneys are bean-shaped organs responsible for filtering waste products from the blood. What is the main nitrogenous waste product the kidneys eliminate?

• A. Carbon dioxide
• B. Ammonia
• C. Urea
• D. Glucose

Correct answer: C

Rationale: The correct answer is C, urea. Urea is the main nitrogenous waste product eliminated by the kidneys. It is produced in the liver from protein metabolism and excreted in urine. Carbon dioxide is eliminated through the lungs as a waste product of cellular respiration and not by the kidneys. Ammonia, a toxic waste product, is converted to urea in the liver before being excreted by the kidneys. Glucose is a sugar that is reabsorbed by the kidneys and not excreted as waste.

4. Which of the following is considered an intensive property?

• A. Mass
• B. Weight
• C. Volume
• D. Density

Correct answer: D

Rationale: Density is an intensive property because it does not depend on the amount of matter present. Intensive properties are independent of the quantity of the substance and remain constant regardless of the size or amount of the sample being measured. Mass, weight, and volume are extensive properties that depend on the amount of substance present. Mass and weight change with the amount of matter, while volume changes as the quantity of the substance changes. Therefore, they are not considered intensive properties.

5. Which of the following suffixes denotes a state or quality?

• A. -ic
• B. -ness
• C. -ous
• D. -ful

Correct answer: B

Rationale: The suffix "-ness" indicates a state or quality, as seen in words like "happiness" (the state of being happy). Choice A, "-ic," typically denotes characteristics or qualities, such as in "heroic." Choice C, "-ous," often signifies the presence of a quality or relationship, like in "poisonous." Choice D, "-ful," usually means full of or characterized by, as in "beautiful." Therefore, the correct answer is B because it best fits the description of indicating a state or quality.
