1. What is the SI unit of measurement for momentum?

Correct answer: B

Rationale: The correct SI unit of measurement for momentum is kilogram-meter per second (kg·m/s). Momentum is a vector quantity that is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second), resulting in the unit kg·m/s. This unit represents the quantity of motion an object possesses, taking into account both the mass and velocity of the object. Choice A, Newton (N), is the unit of force, not momentum. Choice C, Joule (J), is the unit of energy, not momentum. Choice D, Newton-second (N·s), is the unit of impulse, not momentum.

2. Identify the noun clause in the sentence: 'My biggest fear is that I wouldn't live life to the fullest.'

Correct answer: B

Rationale: The correct answer is B, 'that I wouldn't live life to the fullest.' This clause functions as the object of the verb 'is,' making it a noun clause. Noun clauses act as nouns within a sentence, often functioning as subjects, objects, or complements. Choice A ('My biggest fear') is a noun phrase, not a clause. Choice C ('life') and Choice D ('the fullest') are singular nouns and not clauses.

3. What function do genes serve in the relationship between parents and offspring?

Correct answer: A

Rationale: Genes play a crucial role in passing hereditary information from parents to offspring, ensuring the transmission of genetic traits. This process forms the basis of inheritance and genetic continuity between generations. Choice B is incorrect as genes do not prohibit but rather facilitate the transmission of hereditary information. Choice C is incorrect because genes primarily transmit genetic information, while the influence of environmental factors is separate. Choice D is incorrect as genes are fundamental in genetic inheritance and the relationship between parents and offspring.

4. What is 0.5 liters in milliliters?

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 because 1 liter is equal to 1000 milliliters. Therefore, when you convert 0.5 liters to milliliters, you get 500 milliliters (0.5 * 1000 = 500). This conversion is commonly used in various situations where different units of volume are required. Choices B, C, and D are incorrect because they do not follow the correct conversion factor between liters and milliliters.

5. Where does the nerve impulses send neurotransmitters across a synapse to a muscle cell to stimulate muscle contraction?

Correct answer: D

Rationale: The neuromuscular junction is the specific area where nerve impulses trigger the release of neurotransmitters that cross the synaptic gap to bind to receptors on the muscle cell membrane. This binding initiates muscle contraction by stimulating the muscle cell. The sarcomere is the basic contractile unit in a muscle fiber, not the location where nerve impulses communicate with muscle cells. Tendons are connective tissues that attach muscles to bones and are not involved in transmitting nerve impulses. The myelin sheath is a protective covering around nerve fibers but is not directly involved in transmitting neurotransmitters to muscle cells for muscle contraction.
