1. How are mass and inertia related?

• A. Mass is a measure of inertia
• B. Mass has no relationship with inertia
• C. Inertia is a measure of weight
• D. Inertia increases with decreasing mass

Correct answer: A

Rationale: Mass is a measure of inertia. Inertia is the resistance of an object to changes in its state of motion, and mass quantifies this resistance. Objects with more mass have greater inertia, meaning they are more resistant to changes in their motion. Therefore, mass and inertia are directly related, with mass being a fundamental factor that determines the level of inertia an object possesses. Choice B is incorrect because mass and inertia are indeed related. Choice C is incorrect as inertia is not a measure of weight but rather a property related to an object's mass. Choice D is incorrect because inertia actually increases with increasing mass, not decreasing mass.

2. Which structure in the eye is responsible for detecting light?

• A. Cornea
• B. Retina
• C. Lens
• D. Iris

Correct answer: B

Rationale: The retina is the correct answer as it is the light-sensitive structure in the eye that detects light and converts it into signals for the brain to process visual information. The cornea is the transparent outer covering of the eye that helps to focus incoming light onto the lens. The lens further focuses the light onto the retina, which is where the actual light detection and signal conversion occur. The iris, on the other hand, controls the amount of light entering the eye by adjusting the size of the pupil but is not directly responsible for detecting light.

3. Which type of reaction undergoes hydrolysis?

• A. Anabolism
• B. Catabolism
• C. Exothermic
• D. Endothermic

Correct answer: B

Rationale: The correct answer is 'Catabolism.' Catabolic reactions involve the breakdown of larger molecules into smaller ones, often through hydrolysis, where water is added to break chemical bonds. This process is essential for the degradation of complex molecules and the release of energy stored in chemical bonds. Choice A, 'Anabolism,' is incorrect as anabolism involves the synthesis of complex molecules from simpler ones. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat energy exchange during a reaction and are not directly related to the process of hydrolysis.

4. The realtor showed __________ and __________ a house on Wednesday afternoon. Which of the following pronoun pairs should be used in the blanks above?

• A. She, I
• B. She, me
• C. Me, her
• D. Her, me

Correct answer: D

Rationale: In the sentence, 'The realtor showed her and me a house on Wednesday afternoon,' the pronouns 'her' and 'me' are used as objects of the verb 'showed.' When choosing pronouns to fill in the blanks, it is important to use objective pronouns to maintain correct grammar and sentence structure. Choice A ('She, I') and Choice B ('She, me') are incorrect as 'I' and 'she' are subjective pronouns, not objective pronouns needed as objects in this sentence. Choice C ('Me, her') is also incorrect as the order and usage of pronouns are reversed from the correct form in the sentence.

5. A recipe calls for 2.5 teaspoons of vanilla. 1 teaspoon equals approximately 4.93 mL. Which of the following is the correct amount of vanilla in mL?

• A. 5.33 mL
• B. 7.43 mL
• C. 12.325 mL
• D. 0.507 mL

Correct answer: C

Rationale: To convert 2.5 teaspoons of vanilla to milliliters, you multiply by the conversion factor: 2.5 teaspoons * 4.93 mL = 12.325 mL. Therefore, the correct amount of vanilla in milliliters is 12.325 mL. Choice A (5.33 mL) is incorrect because it does not account for the correct conversion factor. Choice B (7.43 mL) is incorrect as it also does not use the accurate conversion factor. Choice D (0.507 mL) is incorrect as it represents a miscalculation of the conversion.
