ATI TEAS 7
Reading
1. Which additional information would be MOST relevant to the topic of the passage?
- A. A detailed history of the development of specific social media platforms.
- B. Studies on the psychological effects of prolonged social media use on teenagers.
- C. Statistics on the global economic impact of the social media industry.
- D. Technical explanations of the algorithms used by social media platforms.
Correct answer: B
Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.
2. What is the name of the sheath of connective tissue that surrounds a skeletal muscle?
- A. Epimysium
- B. Perimysium
- C. Endomysium
- D. Myofibril
Correct answer: A
Rationale: The correct answer is A: Epimysium. The epimysium is the outermost layer of connective tissue that surrounds a skeletal muscle. It provides protection and support to the muscle fibers within, as well as helps in transmitting forces generated by the muscle. Perimysium (B) is the connective tissue that surrounds bundles of muscle fibers called fascicles, while endomysium (C) is the connective tissue that surrounds individual muscle fibers. Myofibril (D) is a structure within muscle fibers that contains the contractile units responsible for muscle contraction. Therefore, in this context, the sheath of connective tissue surrounding a skeletal muscle is specifically referred to as the epimysium.
3. What does "voice" refer to in writing style?
- A. The font and typeface used in the text.
- B. The author's unique perspective and personality.
- C. The specific grammar and punctuation rules followed.
- D. The intended audience and purpose of the writing.
Correct answer: B
Rationale: Voice encompasses the author's personality, tone, and overall approach to crafting the written message.
4. Organisms that break down dead organisms and return nutrients to the environment are called:
- A. Producers
- B. Decomposers
- C. Consumers
- D. Parasites
Correct answer: B
Rationale: Rationale: Decomposers are organisms that break down dead organisms and organic matter, such as bacteria, fungi, and some insects. They play a crucial role in the ecosystem by breaking down complex organic materials into simpler forms, releasing nutrients back into the environment for other organisms to use. Producers (option A) are organisms that produce their own food through photosynthesis, consumers (option C) are organisms that consume other organisms for energy, and parasites (option D) are organisms that live on or in another organism and benefit at the host's expense.
5. Which statement accurately describes the relationship between electron configuration and the periodic table?
- A. Elements within the same period have similar electron configurations.
- B. Elements within the same group have similar electron configurations in their outermost shell.
- C. Electron configuration has no influence on an element's position on the periodic table.
- D. The number of electron shells an element has determines its group on the periodic table.
Correct answer: B
Rationale: Elements within the same group have similar electron configurations in their outermost shell. This explains why elements in the same group often share similar chemical properties.
6. According to the wave theory of light, the bright fringes observed in a double-slit experiment correspond to:
- A. Constructive interference
- B. Destructive interference
- C. Increased diffraction
- D. Total internal reflection
Correct answer: A
Rationale: The correct answer is A: Constructive interference. According to the wave theory of light, when two light waves meet in phase (crest to crest or trough to trough), they combine to produce a brighter fringe. This is known as constructive interference, leading to the formation of bright fringes in a double-slit experiment. Destructive interference, on the other hand, occurs when two waves are out of phase (crest to trough), resulting in a dimmer or dark fringe. Increased diffraction refers to the bending of light waves around obstacles, not the formation of bright fringes. Total internal reflection is a phenomenon that occurs at the boundary between two different mediums when light is reflected back into the original medium. Therefore, the bright fringes observed in a double-slit experiment correspond to constructive interference.
