ATI TEAS 7

TEAS Reading Practice Test

1. The speaker addresses his audience as 'My Good Friends.' What kind of credibility does this salutation give to the speaker?

A. The speaker's salutation is one from an employer to his employees, aiming to bridge the gap between them.
B. The speaker's salutation is one from an entertainer to his audience, using friendly language to connect before a serious speech.
C. The salutation gives the serious speech that follows a somber tone, as it is used ironically.
D. The speech is from a politician to the public, using the salutation to grab the audience's attention.

Correct answer: B

Rationale: The salutation 'My Good Friends' used by Charles Dickens in his speech to the working men and their families in Birmingham shows that he is addressing them as an entertainer, aiming to connect with them before delivering a serious message. This friendly language establishes a personal connection with the audience, setting a tone of camaraderie and warmth. The salutation is not meant to bridge a gap between an employer and employees (Choice A), create irony (Choice C), or grab attention like a politician (Choice D). Instead, it is a genuine and warm address to engage the audience before conveying his earnest hope about the Institute's principles.

2. Why is the electrical conductivity of a strong acid solution higher than that of a weak acid solution?

A. Strong acids are more concentrated.
B. Strong acids release more hydrogen ions.
C. Weak acids are better at dissolving salts.
D. Strong acids have a lower pH.

Correct answer: B

Rationale: The correct answer is B because strong acids release more hydrogen ions compared to weak acids. This higher concentration of ions in the solution leads to a higher electrical conductivity. Strong acids ionize completely in solution, producing a higher concentration of ions that can conduct electricity, whereas weak acids only partially ionize, resulting in a lower concentration of ions and lower electrical conductivity. Choice A is incorrect because the concentration of the acid does not directly determine its electrical conductivity. Choice C is incorrect as the ability to dissolve salts is not directly related to electrical conductivity. Choice D is incorrect because the pH of the solution, although related to acidity, does not directly determine the electrical conductivity.

3. How do organisms maintain homeostasis?

A. By increasing their body temperature, blood pH, and fluid balance.
B. By undergoing biochemical processes and absorbing energy to increase entropy.
C. By undergoing biochemical processes to maintain the order of their external environment.
D. By using free energy and matter via biochemical processes to work against entropy.

Correct answer: D

Rationale: Organisms maintain homeostasis by utilizing free energy and matter through biochemical processes to counteract entropy, which helps in preserving internal stability. This process involves maintaining a balance within the organism's internal environment despite external changes, ensuring proper functioning and survival. Choice A is incorrect because increasing body temperature, blood pH, and fluid balance alone do not define the comprehensive process of maintaining homeostasis. Choice B is incorrect as absorbing energy to increase entropy goes against the concept of maintaining internal stability. Choice C is incorrect as maintaining the order of the external environment does not directly contribute to the organism's internal stability and balance.

4. The scatter plot below shows the relationship between the students' exam scores and their heights. Which type of correlation is depicted in the scatter plot?

A. Positive
B. Positive and Negative
C. Negative
D. No correlation

Correct answer: D

Rationale: The scatter plot illustrates the relationship between students' exam scores and heights. There is no correlation between these variables, as height is not expected to have a direct impact on exam scores. Therefore, choice D, 'No correlation,' is the correct answer. Choices A, 'Positive,' and C, 'Negative,' are incorrect because the scatter plot does not indicate a positive or negative correlation between exam scores and heights. Choice B, 'Positive and Negative,' is also incorrect because the scatter plot does not exhibit both positive and negative correlations simultaneously.

5. What is 0.2 mg converted to mcg?

A. 200 mcg
B. 20 mcg
C. 2000 mcg
D. 2 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.2 mg * 1000 = 200 mcg. This is the correct conversion. Choice B (20 mcg) is incorrect because it does not account for multiplying by 1000. Choice C (2000 mcg) is incorrect as it mistakenly multiplies by 10 instead of 1000. Choice D (2 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.
