TEAS 7 science quizlet
1. Which types of waves are capable of interference and diffraction?
- A. Longitudinal waves only
- B. Transverse waves only
- C. Electromagnetic waves only
- D. Both longitudinal and transverse waves
Correct answer: D
Rationale: Both longitudinal and transverse waves are capable of interference and diffraction. Interference occurs when two or more waves overlap and combine, either constructively (increasing amplitude) or destructively (decreasing amplitude). Diffraction is the bending of waves around obstacles or through openings, which can occur with both longitudinal and transverse waves. Choice A is incorrect because only stating longitudinal waves can undergo interference and diffraction is inaccurate. Choice B is also incorrect as transverse waves, not just longitudinal waves, can exhibit these phenomena. Choice C is incorrect because electromagnetic waves are a broad category that includes both longitudinal and transverse waves, so it is not exclusive to either type. The correct answer is D because both longitudinal and transverse waves can demonstrate interference and diffraction.
2. What is the role of surfactant in the respiratory system?
- A. To trap dust particles
- B. To increase lung compliance
- C. To produce mucus
- D. To generate oxygen during respiration
Correct answer: B
Rationale: The correct answer is B: To increase lung compliance. Surfactant is a substance produced by type II alveolar cells in the lungs that reduces surface tension in the alveoli. This reduction in surface tension helps to increase lung compliance, making it easier for the lungs to expand and contract during breathing. Improved lung compliance is essential for efficient gas exchange in the respiratory system, facilitating oxygen uptake and carbon dioxide removal. Choices A, C, and D are incorrect because surfactant does not trap dust particles, produce mucus, or generate oxygen during respiration. Instead, its primary function lies in reducing surface tension to prevent alveolar collapse and improve lung compliance for optimal gas exchange.
3. Which word(s) in the following sentence should be capitalized? 'She asked, Do you like Indian food?'
- A. She and do
- B. Do and Indian
- C. She and Indian
- D. She, do, and Indian
Correct answer: D
Rationale: In the given sentence, the words that should be capitalized are 'She,' 'do,' and 'Indian.' 'She' needs to be capitalized as it is the pronoun referring to a person, 'do' should be capitalized as it is the beginning of a question, and 'Indian' should be capitalized as it refers to a specific nationality or culture. Choice A is incorrect as 'do' is missing. Choice B is incorrect as 'Indian' is not capitalized. Choice C is incorrect as 'Indian' is not capitalized. Therefore, the correct answer is D.
4. What best describes Samuel's sample size?
- A. The sample is biased because it has firsthand experience.
- B. The sample contains too few members to draw meaningful conclusions.
- C. The sample contains too many members to make specific claims.
- D. The sample is unbiased and of appropriate size.
Correct answer: B
Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.
5. Given the style of writing for the passage, which of the following magazines would be the best fit for this article?
- A. Scientific Spelunking
- B. Family Fun Days
- C. Adventures for Men
- D. Mud Magazine
Correct answer: B
Rationale: The article's style is light-hearted and aimed at families looking for outdoor adventures. It suggests activities suitable for families with children, making Family Fun Days the best fit among the given magazine options. 'Scientific Spelunking' may focus more on the scientific aspects rather than family-friendly fun. 'Adventures for Men' may cater to a male audience rather than families. 'Mud Magazine' seems more focused on mud-related content, which doesn't align with the family-friendly, outdoor adventure theme of the article.
