1. What is any number raised to the power of 1?

• A. Itself
• B. One
• C. Zero
• D. The number multiplied by 2

Correct answer: A

Rationale: The correct answer is A: 'Itself.' When any number is raised to the power of 1, it remains unchanged and is equal to itself. This is a fundamental property of exponents. Choice B, 'One,' is incorrect because raising a number to the power of 1 does not result in the answer being 1. Choice C, 'Zero,' is incorrect as any non-zero number raised to the power of 1 is itself, not zero. Choice D, 'The number multiplied by 2,' is incorrect because raising a number to the power of 1 does not involve multiplying it by 2.

2. Which of the following is not an example given by the author of an element of the Western paradigm?

• A. Hero highly skilled at warfare
• B. Evil villain in black hat
• C. Everyone riding horses
• D. Community made up of upstanding citizens

Correct answer: C

Rationale: The author did not mention everyone riding horses as an element of the Western paradigm in the provided passage. The passage discusses the virtuous hero in the white hat, the evil villain in the black hat, and the community made up of upstanding citizens as elements of the Western paradigm. The hero being highly skilled at warfare and the community having morally upstanding citizens were also mentioned. Therefore, option C is the correct answer. Options A, B, and D are incorrect because they were all examples given by the author in the passage.

3. What is an electrically charged atom called?

• A. Ion
• B. Isotope
• C. Molecule
• D. Compound

Correct answer: A

Rationale: An ion is an atom that has gained or lost electrons, resulting in a positive or negative charge, making it electrically charged. This term specifically refers to atoms with a net electrical charge. Isotopes are atoms of the same element with different numbers of neutrons, not electrically charged. Molecules are formed when atoms bond together, but they are not necessarily charged. Compounds are substances composed of different elements bonded together, but they may not be electrically charged.

4. An object is initially at rest. Which of the following will definitely NOT cause it to move?

• A. A constant force acting on it
• B. No force acting on it
• C. A force that increases in magnitude over time
• D. A force that decreases in magnitude over time

Correct answer: B

Rationale: The correct answer is B because if an object is initially at rest and no force is acting on it, it will remain at rest due to Newton's First Law of Motion. This law states that an object at rest will stay at rest unless acted upon by an external force. Choices A, C, and D all involve forces acting on the object, which would cause it to move according to Newton's laws of motion. Choice A, a constant force acting on the object, would cause it to move at a constant velocity. Choice C, a force that increases in magnitude over time, would accelerate the object. Choice D, a force that decreases in magnitude over time, would decelerate the object.

5. What enzymes do lysosomes contain, leading to their nickname as the cell's 'suicide bags'?

• A. Hydrolytic enzymes
• B. Ligases (bonding enzymes)
• C. Transferases (molecule transfer)
• D. Oxidoreductases (redox reactions)

Correct answer: A

Rationale: Lysosomes are organelles filled with hydrolytic enzymes that break down proteins, nucleic acids, lipids, and carbohydrates. These enzymes aid in digesting cellular waste and foreign substances, hence the term 'suicide bags' due to their involvement in cell degradation and recycling. Ligases are enzymes that catalyze the joining of two large molecules by forming a new chemical bond, not present in lysosomes. Transferases are enzymes that catalyze the transfer of functional groups from one molecule to another, not found in lysosomes. Oxidoreductases are enzymes involved in oxidation-reduction reactions, which are not the primary function of lysosomes.
