1. Which of the following statements is true about the dependent variable?

• A. A factor that remains constant during the experiment
• B. A factor with data typically plotted on the x-axis
• C. A factor that is measured during an experiment
• D. A factor with data typically plotted on the y-axis

Correct answer: C

Rationale: The correct answer is C. The dependent variable is the factor that is being measured or observed in an experiment. It is the outcome that is affected by changes in the independent variable. In graphical representations, the dependent variable is usually plotted on the y-axis, not the x-axis. Choice A is incorrect because a factor that remains constant is referred to as a constant, not a dependent variable. Choice B is incorrect as the independent variable's data is typically plotted on the x-axis. Choice D is incorrect because the dependent variable's data is usually plotted on the y-axis. Therefore, choice C accurately describes the dependent variable.

2. Which term refers to the resistance of a liquid to flow?

• A. Density
• B. Viscosity
• C. Surface tension
• D. Boiling point

Correct answer: B

Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is and determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume and is not related to the resistance of a liquid to flow. Surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, but it is not directly related to the resistance of a liquid to flow. Boiling point (D) is the temperature at which a liquid changes to a vapor and is not a measure of the resistance of a liquid to flow.

3. Which condition is commonly associated with frequent, painful urination?

• A. Diabetes
• B. Urinary tract infection (UTI)
• C. Kidney stones
• D. All of the above

Correct answer: D

Rationale: Frequent, painful urination can be indicative of various conditions. Diabetes may cause increased urination due to high blood sugar levels, UTIs can lead to pain and frequent urination, and kidney stones can also result in painful urination. Therefore, all of the options (A, B, and C) are correct in this scenario, making option D, 'All of the above,' the correct answer. Option D encompasses all the conditions commonly associated with frequent, painful urination, making it the most comprehensive and accurate choice.

4. Which of the following best describes the statement 'This flower is dead; someone must have forgotten to water it'?

• A. A classification
• B. An observation
• C. An inference
• D. A collection

Correct answer: C

Rationale: The correct answer is 'C: An inference.' An inference is a conclusion reached based on evidence and reasoning. In this statement, the conclusion that someone must have forgotten to water the flower is drawn from the evidence that the flower is dead. Choice A, 'A classification,' is incorrect because the statement does not involve categorizing or grouping. Choice B, 'An observation,' is incorrect as the statement goes beyond just stating a fact and makes a conclusion. Choice D, 'A collection,' is unrelated to the process of drawing a conclusion based on the given evidence.

5. What is the longest bone in the human body?

• A. Tibia
• B. Fibula
• C. Femur
• D. Humerus

Correct answer: C

Rationale: The femur is indeed the longest bone in the human body. It extends from the hip to the knee, providing crucial support for the body's weight and enabling various movements. The tibia and fibula are bones in the lower leg, while the humerus is located in the upper arm. Therefore, choices A, B, and D are incorrect in this context.
