ATI TEAS 7
English Grammar
1. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."
- A. extreme
- B. great
- C. utter
- D. remarkable
Correct answer: C
Rationale: Option C emphasizes the absolute and complete accuracy of the experiment.
2. What tool helps scientists identify and classify organisms based on their shared characteristics?
- A. Binomial nomenclature
- B. Cladistics
- C. Dichotomous key
- D. Domain-based classification
Correct answer: C
Rationale: Rationale: A) Binomial nomenclature is a system used to give each organism a two-part scientific name (genus and species) but does not help in identifying or classifying organisms based on shared characteristics. B) Cladistics is a method of classification based on evolutionary relationships and shared characteristics, but it is not a tool used for identifying organisms. C) Dichotomous key is a tool that helps scientists identify and classify organisms based on their shared characteristics by presenting a series of choices leading the user to the correct identification. D) Domain-based classification is a system of classification that groups organisms into three domains (Bacteria, Archaea, Eukarya) based on molecular and genetic similarities, but it is not a tool used for identifying organisms based on shared characteristics.
3. Which technique best helps maintain consistency in writing style?
- A. Writing freely without a clear outline or structure.
- B. Using different vocabulary and sentence structures in each paragraph.
- C. Establishing a style guide with agreed-upon terminology and formatting.
- D. Relying on thesaurus suggestions for varied word choices.
Correct answer: C
Rationale: A style guide ensures consistency in tone, terminology, and formatting across different pieces of writing.
4. The term "barn" is a unit commonly used in nuclear physics to quantify:
- A. Energy (Electron volts are the standard unit for energy in nuclear physics)
- B. Radioactivity
- C. Nuclear cross-section
- D. Half-life
Correct answer: C
Rationale: The term 'barn' is a unit of measurement used in nuclear physics to quantify nuclear cross-section. Nuclear cross-section refers to the measure of the probability of a specific interaction occurring between particles during a nuclear reaction. The term 'barn' was coined based on its relation to the physical size of a nucleus, as it is a small unit of area used to describe the likelihood of a particle interacting with a nucleus. It is not used to quantify energy, radioactivity, or half-life, making options A, B, and D incorrect in this context.
5. What kind of bond links amino acids together?
- A. Hydrogen bond
- B. Ionic bond
- C. Disulfide bond
- D. Covalent bond
Correct answer: D
Rationale: Rationale: Amino acids are linked together by covalent bonds to form proteins. A covalent bond is a strong chemical bond formed by the sharing of electrons between atoms. In the case of amino acids, the covalent bond that links them together is called a peptide bond. This bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, resulting in the formation of a peptide chain. Hydrogen bonds, ionic bonds, and disulfide bonds can also play roles in protein structure and stability, but the primary bond linking amino acids together in a protein chain is the covalent peptide bond.
6. hich word is most closely associated with the adjective "meticulous"?
- A. careless
- B. precise
- C. indifferent
- D. enthusiastic
Correct answer: B
Rationale: "Meticulous" implies carefulness and attention to detail, making "precise" its closest synonym.
