Practice English TEAS TEST
1. Brady had never been skiing before. She took to the slopes like a natural.
- A. Unless
- B. But
- C. Therefore
- D. Before
Correct answer: B
Rationale: The correct answer is 'But.' In this context, 'But' is a conjunction that correctly connects the two independent clauses, indicating a contrast. The first sentence states that Brady had never skied before, while the second sentence reveals that she performed well on the slopes, showing a surprising contrast to her lack of experience. 'Unless' implies a condition that needs to be met for a particular situation, which is not relevant here. 'Therefore' indicates a conclusion or result, which does not fit the context of the contrasting statements. 'Before' is a preposition that doesn't serve the purpose of connecting the two ideas presented in the sentences.
2. In the sentence 'The flustered man watched the train as it pulled out of the station,' which of the following is the simple subject?
- A. man
- B. the flustered man
- C. watched
- D. train
Correct answer: A
Rationale: The simple subject is the noun or pronoun that the sentence is about. In this sentence, the subject is 'man' because it is the entity performing the action of watching. 'The flustered man' is a noun phrase but not the simple subject as it includes an article and an adjective. 'Watched' is a verb and 'train' is the object of the action, not the subject. Therefore, 'man' is the correct simple subject in this sentence.
3. A botanist wants to determine if environmental temperature affects root growth. What is the independent variable in this study?
- A. Temperature
- B. Seedlings
- C. Light
- D. Root length
Correct answer: A
Rationale: The correct answer is 'Temperature.' In an experiment, the independent variable is the factor that is deliberately manipulated or changed by the researcher. In this study, the botanist is specifically investigating how environmental temperature affects root growth, making temperature the independent variable. Choice B, 'Seedlings,' and Choice C, 'Light,' are not the independent variables in this context as they are not the factors being intentionally changed or manipulated. Choice D, 'Root length,' is the dependent variable, as it is the outcome that is being measured or observed in response to the changes in the independent variable, temperature.
4. Which statement confirms that the cell membrane is selectively permeable?
- A. Receptors are found on a cell's surface.
- B. Cells communicate with each other using cell signals.
- C. Environmental changes can cause a cell to expand or shrink.
- D. Sodium ions must travel through ion channels to enter the cell.
Correct answer: D
Rationale: The correct answer is D because selective permeability is demonstrated by the fact that specific ions, such as sodium, require ion channels to cross the cell membrane. This process allows the cell to control what substances can enter or exit, highlighting the selective nature of the cell membrane. Choices A, B, and C do not directly relate to the concept of selective permeability of the cell membrane. Receptors on a cell's surface (Choice A) are involved in cell signaling rather than selective permeability. Cell communication through signals (Choice B) and environmental changes affecting cell size (Choice C) are not directly related to the selective permeability of the cell membrane, which specifically refers to the regulation of substances passing through the membrane.
5. Which of the following is not a biological macromolecule?
- A. Glycoproteins
- B. DNA
- C. Phospholipid
- D. Glucose
Correct answer: D
Rationale: Glucose is a monosaccharide, which is a simple sugar and not a macromolecule. Glycoproteins, DNA, and phospholipids are all examples of biological macromolecules. Glycoproteins are proteins covalently bonded to carbohydrates, DNA is a nucleic acid, and phospholipids are lipids that contain a phosphate group.
