TEAS – Test of Essential Academic Skills Practice Questions
1. Which organelle is responsible for producing the majority of a cell's ATP?
1. Nucleus
2. Mitochondria
3. Golgi apparatus
4. Ribosome
Answer: 2. Mitochondria
Rationale: Mitochondria are known as the 'powerhouse of the cell,' generating the majority of a cell's ATP
through cellular respiration.
2. Solve: If a solution is diluted from 500 mL of a 10% solution to a final volume of 1000 mL, what is the new
concentration?
1. 20%
2. 10%
3. 5%
4. 2.5%
Answer: 3. 5%
Rationale: Using C1V1 = C2V2: (10%)(500 mL) = C2(1000 mL), so C2 = 5%. Diluting the solution to double
its volume halves its concentration.
3. Which part of speech describes a word that modifies a noun?
1. Adverb
2. Adjective
3. Conjunction
4. Preposition
Answer: 2. Adjective
Rationale: An adjective modifies or describes a noun, providing more detail about its qualities (e.g., size, color,
or condition).
4. What is the correct order of the phases of mitosis?
1. Telophase, Anaphase, Metaphase, Prophase
2. Prophase, Metaphase, Anaphase, Telophase
3. Metaphase, Prophase, Telophase, Anaphase
4. Anaphase, Telophase, Prophase, Metaphase
Answer: 2. Prophase, Metaphase, Anaphase, Telophase
Rationale: The correct order of mitosis is Prophase, Metaphase, Anaphase, and Telophase (often remembered
by the mnemonic PMAT).
5. A patient's temperature is 38.5°C. What is this temperature in Fahrenheit?
1. 97.7°F
2. 101.3°F
3. 99.5°F
4. 103.1°F
Answer: 2. 101.3°F
Rationale: Using F = (C × 9/5) + 32: (38.5 × 1.8) + 32 = 69.3 + 32 = 101.3°F.
6. Which of the following best describes an independent variable in a scientific experiment?
