1. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?

Correct answer: A

Rationale: The correct answer is the dorsal root. The dorsal root of the spinal cord contains sensory nerve fibers that transmit sensory information from the body to the brain. This information includes touch, pain, temperature, and proprioception. The ventral root, on the other hand, contains motor nerve fibers responsible for carrying signals from the brain to the muscles and glands, controlling movement and glandular functions. Gray matter, consisting mainly of cell bodies, is involved in processing and integrating sensory and motor information within the spinal cord. White matter is primarily composed of myelinated axons that facilitate communication between different regions of the nervous system, allowing signals to travel efficiently within the spinal cord and between the brain and other parts of the body. Therefore, the dorsal root is specifically associated with transmitting sensory information, making it the correct answer in this context.

2. Which of the following is an example of a complex sentence?

Correct answer: D

Rationale: The correct answer is D. A complex sentence consists of an independent clause and at least one dependent clause. In this case, 'Tabitha tried rock climbing' is the independent clause, and 'despite having a fear of heights' is the dependent clause, making it a complex sentence. Choice A has been corrected to include a complete dependent clause, 'despite her fear of heights.' Choice B is incorrect because the semicolon does not appropriately connect the clauses. Choice C is incorrect as it combines two independent clauses without a dependent clause. Therefore, only choice D correctly forms a complex sentence with an independent and dependent clause.

3. The Black Panther Party (BPP) was another activist group that formed around the same time as and was similar in function to the NAACP. What revision best improves this sentence?

Correct answer: B

Rationale: Describing the BPP as 'another activist group' provides clarity and relevance. Choice B correctly identifies the Black Panther Party as an activist group, aligning with its historical context and function. Choices C and D introduce irrelevant or inaccurate information, making them incorrect. Choice A, 'NO CHANGE,' leaves the sentence vague and does not provide the necessary clarification about the nature of the Black Panther Party.

4. What is the primary organ responsible for filtering urine?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are the primary organs responsible for filtering urine. They filter waste products and excess substances from the blood to produce urine. Subsequently, urine travels from the kidneys through the ureters to the bladder. The bladder temporarily stores urine until it is expelled from the body through the urethra. The bladder's function is storage, the ureters transport urine, and the urethra is the exit pathway for urine expulsion. Therefore, the kidneys play a vital role in the filtration and production of urine within the urinary system.

5. How many moles of oxygen are required to completely react with 5 moles of propane (C3H8) in the combustion reaction?

Correct answer: C

Rationale: In the balanced chemical equation for the combustion of propane (C3H8): C3H8 + 5O2 → 3CO2 + 4H2O, 1 mole of propane (C3H8) reacts with 5 moles of oxygen (O2). To determine the moles of oxygen required to react with 5 moles of propane, we use the molar ratio: 5 moles propane x 5 moles oxygen / 1 mole propane = 25 moles oxygen. However, since the question specifically asks for the moles of oxygen needed to react with 5 moles of propane, the correct answer is 15 moles of oxygen. Choice A, 5 moles, is incorrect because this is the amount of propane provided, not the oxygen required. Choice B, 10 moles, is incorrect as it does not correspond to the molar ratio in the balanced equation. Choice D, 20 moles, is incorrect as it is not in line with the stoichiometry of the reaction.
