TEAS Test 7 science

1. What does the term 'colligative property' refer to in solutions?

A. Properties that depend on the nature of the solute particles
B. Properties that depend on the concentration of solute particles
C. Properties that depend on the temperature of the solution
D. Properties that depend on the pressure of the solution

Correct answer: B

Rationale: Colligative properties are properties of a solution that depend on the concentration of solute particles, regardless of the identity of the solute. These properties include lowering the vapor pressure, elevation of boiling point, depression of freezing point, and osmotic pressure. The concentration of solute particles affects these properties, not the nature, temperature, or pressure of the solution. Therefore, choice B is the correct answer as it accurately reflects the definition of colligative properties. Choices A, C, and D are incorrect because colligative properties are not based on the nature, temperature, or pressure of the solute, but rather on the concentration of solute particles in the solution.

2. Which of the following words are synonyms for 'erroneously' as used in the passage? (select all that apply)

A. Incorrectly
B. Inconsequentially
C. Mistakenly
D. Extraneously

Correct answer: A, C

Rationale: 'Erroneously' means incorrectly or mistakenly, which aligns with the context provided in the passage. Therefore, 'Incorrectly' and 'Mistakenly' are synonyms for 'erroneously.' 'Inconsequentially' means not resulting in any significant consequence, which is not synonymous with 'erroneously.' 'Extraneously' means irrelevant or unnecessary, which is also not a synonym for 'erroneously.'

3. Which of the following sentences is spelled correctly?

A. He always adds insightful, relevant remarks to the conversation.
B. Her comments were relevant to the class discussion.
C. His remarks were not relevant to the current situation.
D. Her suggestion has no relevance to issues discussed at the conference.

Correct answer: A

Rationale: Choice A is the correct answer. The word 'relevant' is spelled correctly in this sentence, and the sentence is well-constructed. In Choices B, C, and D, the word 'relevant' is misspelled as 'revelant,' 'relevent,' and 'relavance' respectively. These incorrect spellings make Choices B, C, and D grammatically incorrect, thereby making Choice A the only correct option.

4. What is the building block of RNA?

A. Amino acid
B. Nucleotide
C. Protein
D. Fatty acid

Correct answer: B

Rationale: Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. A) Amino acid: Amino acids are the building blocks of proteins, not RNA. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

5. Which word is most closely synonymous with the word 'patronage' as it appears in the following statement? '...that I am sure he will need no charitable aid or condescending patronage.'

A. Auspices
B. Aberration
C. Acerbic
D. Adulation

Correct answer: A

Rationale: The correct answer is 'Auspices.' 'Auspices' is closely related to 'patronage' in the sense of support or sponsorship. In the context of the excerpt, it conveys the idea that the working man will not require condescending support or sponsorship but will actively participate and contribute to the Institute. The other choices are incorrect: 'Aberration' means a deviation from the norm, 'Acerbic' means sharp or bitter in tone, and 'Adulation' means excessive admiration or praise, none of which align with the meaning of 'patronage' in this context.
