ATI TEAS 7
physics
1. Which of the following represents a form of potential energy?
- A. A moving car
- B. A spinning top
- C. A raised hammer
- D. A rolling ball
Correct answer: c
Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.
2. Which of the following is a redox reaction?
- A. 2H2 + O2 → 2H2O
- B. Zn + 2HCl → ZnCl2 + H2
- C. 2NaCl → 2Na + Cl2
- D. CH4 + 2O2 → CO2 + 2H2O
Correct answer: b
Rationale: The oxidation state of Zn changes from 0 to +2, indicating a redox reaction.
3. Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.
- A. 37°C (Normal)
- B. 39°C (Low-grade fever)
- C. 39°C (Fever)
- D. 42°C (Hyperthermia)
Correct answer: C
Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. 2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius: °C = (102 - 32) x 5/9 °C = 70 x 5/9 °C = 350/9 °C ≈ 38.9°C, which can be rounded to 39°C. 3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C
4. What is the main topic of the passage?
- A. Benefits of bioremediation in cleaning oil spills.
- B. Dangers of microplastics to marine ecosystems.
- C. History of plastic production and its global impact.
- D. Comparison of different waste management strategies.
Correct answer: B
Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.
5. Tissues are groups of cells with similar:
- A. Appearance only
- B. Function and structure
- C. Location only
- D. Age only
Correct answer: B
Rationale: The correct answer is B: 'Function and structure.' Tissues are groups of cells that work together to perform a specific function in the body. These cells have both similar functions, such as carrying out a specific task like contracting in muscle tissue, and similar structures, such as having similar shapes or types of organelles. This allows them to work together efficiently and effectively. Choices A, C, and D are incorrect because tissues are defined by more than just appearance, location, or age; they are primarily characterized by their shared function and structure.
6. The phrase "massive open online courses" (MOOCs) refers to
- A. Online learning platforms designed specifically for students with disabilities.
- B. University-level courses freely available to anyone with an internet connection.
- C. Interactive training modules aimed at developing job-specific skills and knowledge.
- D. Online resources offering personalized learning experiences tailored to individual needs.
Correct answer: B
Rationale: MOOCs by definition are open and accessible courses, aligning with B.
