English Grammar

1. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."

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?

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?

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:

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?

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"?

Correct answer: B

Rationale: "Meticulous" implies carefulness and attention to detail, making "precise" its closest synonym.
