1. Water is considered a universal solvent due to its ____.

• A. Cohesion
• B. Adhesion
• C. Molarity
• D. Dilution

Correct answer: B

Rationale: The correct answer is B: Adhesion. Water's polarity allows it to dissolve many substances due to its ability to adhere to and interact with other molecules, making it an effective solvent. Cohesion refers to water molecules sticking together, molarity is a measure of concentration, and dilution refers to the process of reducing the concentration of a solute in a solution, none of which directly relate to water's role as a universal solvent.

2. What are Mendel's laws?

• A. Law of inheritance, law of expression
• B. Law of segregation, law of independent assortment
• C. Law of dominance, law of recessiveness
• D. Law of mutation, law of crossing over

Correct answer: B

Rationale: The correct answer is B. Mendel's laws consist of the law of segregation, which states that each parent passes one allele for each trait, and the law of independent assortment, which explains that genes for different traits are inherited independently. Choice A is incorrect because 'law of expression' is not one of Mendel's laws. Choice C is incorrect because 'law of dominance' and 'law of recessiveness' do not represent the two main laws proposed by Mendel. Choice D is incorrect because 'law of mutation' and 'law of crossing over' are not part of Mendel's original laws.

3. What is the formula to calculate acceleration?

• A. Acceleration = Mass/Force
• B. Acceleration = Force/Mass
• C. Acceleration = Time/Distance
• D. Acceleration = Time Change in Velocity

Correct answer: D

Rationale: Acceleration is defined as the rate of change of velocity with respect to time. The correct formula to calculate acceleration is Acceleration = Time Change in Velocity. This formula specifically represents how much an object's velocity changes over a specified time period, providing a measure of the object's speed change rate. Choices A and B are incorrect as they do not represent the relationship between acceleration and time change in velocity. Choice C is incorrect as it involves time and distance, which are not directly related to acceleration.

4. Identify the subject in the following sentence: 'The red car parked in the driveway.'

• A. driveway
• B. red
• C. car
• D. the

Correct answer: C

Rationale: In the sentence 'The red car parked in the driveway,' the subject is 'car' because it is the noun that is performing the action of parking. The subject is typically the main noun that the rest of the sentence revolves around. 'Driveway' is part of the prepositional phrase 'in the driveway.' 'Red' is an adjective describing the car, and 'the' is an article providing information about the car but not the main noun carrying out the action.

5. Which of the following punctuation marks correctly completes the sentence below? "She bought several items for the trip____ a tent, a sleeping bag, and a flashlight."

• A. ;
• B. :
• C. ,
• D. .

Correct answer: B

Rationale: The correct punctuation mark to use in this sentence is the colon (:) because it is used to introduce a list. In this case, the list of items she bought for the trip includes a tent, a sleeping bag, and a flashlight. A semicolon (;) is not appropriate here because it is typically used to connect independent clauses. A comma (,) is not suitable as it would create a comma splice error. A period (.) is incorrect as it signifies the end of a sentence, which is not the intended purpose in this context.
