TEAS Test English Questions
1. After a long, exhausting hike, Stephanie went home and fell asleep on the couch, which she had done many times before. Which comma should be removed in the sentence above?
- A. The comma after the word 'long'
- B. The comma after the word 'hike'
- C. The comma after the word 'home'
- D. The comma after the word 'couch'
Correct answer: C
Rationale: The comma after 'home' is unnecessary and should be removed. In this sentence, 'and' is joining two independent clauses, which doesn't require a comma before it. Choices A, B, and D are incorrect because they are correctly placed commas within the sentence.
2. How many milliliters are in 2 liters?
- A. 20 mL
- B. 200 mL
- C. 2,000 mL
- D. 20,000 mL
Correct answer: C
Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 since there are 1,000 milliliters in 1 liter. Therefore, 2 liters x 1,000 = 2,000 milliliters. Choices A, B, and D are incorrect because they do not account for the correct conversion factor from liters to milliliters.
3. Which macromolecule will always contain nitrogen?
- A. Fatty acid
- B. Protein
- C. Lipid
- D. Carbohydrate
Correct answer: B
Rationale: The correct answer is B: Protein. Proteins always contain nitrogen, as it is a key element in amino acids, the building blocks of proteins. Fatty acids (choice A), lipids (choice C), and carbohydrates (choice D) do not always contain nitrogen. Fatty acids consist of long chains of hydrocarbons, lipids are mainly composed of carbon, hydrogen, and oxygen, and carbohydrates are composed of carbon, hydrogen, and oxygen as well, but not nitrogen.
4. Which of the following organelles is responsible for protein production in the cell?
- A. Ribosomes
- B. Golgi apparatus
- C. Mitochondria
- D. Lysosomes
Correct answer: A
Rationale: The correct answer is A: Ribosomes. Ribosomes are the organelles responsible for protein synthesis in the cell. They can be found either freely floating in the cytoplasm or attached to the endoplasmic reticulum. The Golgi apparatus (Choice B) is involved in processing and packaging proteins, not protein production. Mitochondria (Choice C) are responsible for energy production, not protein synthesis. Lysosomes (Choice D) are involved in digestion and waste removal, not protein production.
5. Which type of reaction builds larger and more complex molecules from smaller ones, requiring energy?
- A. Catabolic reaction
- B. Anabolic reaction
- C. Exothermic reaction
- D. Hydrolytic reaction
Correct answer: B
Rationale: The correct answer is 'Anabolic reaction.' Anabolic reactions involve the synthesis of larger and more complex molecules from smaller ones, requiring an input of energy, often in the form of ATP. These reactions are essential for processes like growth, repair, and the building of cellular structures. Catabolic reactions, on the other hand, break down larger molecules into smaller ones, releasing energy. Exothermic reactions release heat, while hydrolytic reactions involve the breakdown of molecules with the addition of water. Therefore, choices A, C, and D are incorrect as they do not describe the process of building larger and more complex molecules from smaller ones with the requirement of energy.
