TEAS 7 English Practice Test
1. If the word antibacterial describes a substance that kills bacteria, you can infer that the prefix anti-means:
- A. Original to
- B. Against
- C. Before
- D. Under
Correct answer: B
Rationale: The correct answer is 'B: Against.' The prefix 'anti-' means 'against,' as seen in the word 'antibacterial,' which denotes something that acts against bacteria. Choice A, 'Original to,' is incorrect as the prefix 'anti-' does not imply 'original to.' Choice C, 'Before,' is incorrect as 'anti-' does not signify 'before' but rather 'against.' Choice D, 'Under,' is also incorrect as 'anti-' does not convey the idea of being 'under' but rather 'against' in this context.
2. A student hypothesizes that higher sugar consumption negatively impacts test scores. To investigate this, the student recruits participants to consume varying amounts of sugar, wait for one hour, and then complete an aptitude test. The student will record both the amount of sugar consumed and the test scores to analyze the relationship. What is the best experimental approach?
- A. Conduct one round of testing where each participant consumes a different amount of sugar.
- B. Conduct two rounds of testing: In the first round, participants consume varying amounts of sugar; in the second round, they consume the same amount of sugar as they did in the first round.
- C. Conduct two rounds of testing: In the first round, participants consume varying amounts of sugar; in the second round, participants consume no sugar.
- D. Conduct one round of testing where all participants consume the same amount of sugar.
Correct answer: C
Rationale: Option C provides the most thorough experimental design by including a control group. In the first round, varying sugar intake levels help explore the relationship between sugar consumption and test scores. In the second round, by having participants consume no sugar, the student can compare results to observe any changes due to sugar intake. This approach enhances the validity of the findings by accounting for potential confounding factors and better identifying causal relationships. Choice A is not ideal as it lacks a control group and does not compare the impact of sugar consumption. Choice B does not explore the effects of sugar consumption adequately as it does not include a group without sugar. Choice D does not allow for comparison between different sugar consumption levels, limiting the ability to draw meaningful conclusions.
3. What is the role of the pancreas in the digestive system?
- A. To store bile
- B. To secrete digestive enzymes
- C. To digest proteins
- D. To absorb nutrients
Correct answer: B
Rationale: The correct answer is B: 'To secrete digestive enzymes.' The pancreas plays a crucial role in the digestive system by secreting digestive enzymes that aid in breaking down food in the small intestine. These enzymes help in the digestion of carbohydrates, fats, and proteins, facilitating the absorption of nutrients from the digested food. Choice A is incorrect because the pancreas is not responsible for storing bile; the gallbladder stores bile. Choice C is incorrect because the pancreas secretes enzymes for protein digestion but does not digest proteins itself. Choice D is incorrect as the absorption of nutrients primarily occurs in the small intestine, not in the pancreas.
4. The plane ride was terrible, and they got home three hours late: _______ they never made it to the wedding.
- A. although
- B. conversely
- C. unless
- D. consequently
Correct answer: D
Rationale: The correct answer is 'consequently.' In this sentence, 'consequently' is used to show the result of their late arrival, leading to them missing the wedding. 'Although' (choice A) is incorrect because it suggests a contrast rather than a cause-effect relationship. 'Conversely' (choice B) is also incorrect as it indicates a contrasting idea. 'Unless' (choice C) introduces a condition, which doesn't fit the context of the sentence. Therefore, 'consequently' best connects the delay to missing the wedding.
5. Which of the following is an example of stabilizing selection?
- A. Selection that favors extreme traits in a population
- B. Selection that removes individuals with extreme traits
- C. Selection that maintains the current average trait in a population
- D. Selection that favors one specific trait over all others
Correct answer: C
Rationale: - Stabilizing selection is a type of natural selection that favors the intermediate variants in a population, while selecting against the extreme traits. This results in the maintenance of the current average trait in the population. - Option A is incorrect because stabilizing selection does not favor extreme traits; instead, it favors the average trait. - Option B is incorrect because stabilizing selection does not remove individuals with extreme traits; it acts against extreme traits by favoring the intermediate variants. - Option D is incorrect because stabilizing selection does not favor one specific trait over all others; it favors the average trait by selecting against extreme traits.
