ATI TEAS 7
TEAS Test 7 science quizlet
1. What phenomenon occurs when light passes through a medium without changing direction, such as when passing through a window?
- A. Diffraction
- B. Reflection
- C. Dispersion
- D. Transmission
Correct answer: D
Rationale: The correct answer is 'Transmission.' Transmission refers to the phenomenon where light passes through a medium without changing direction, as observed when light passes through a window. Diffraction involves the bending of light waves around obstacles, reflection is the bouncing back of light waves from a surface, and dispersion is the separation of light into its different colors. In this case, the question specifically asks about the situation where light passes through a medium without changing direction, which aligns with the process of transmission.
2. Which of the following statements is true about Noble gases?
- A. They are non-reactive.
- B. They are highly reactive.
- C. They have 8 valence electrons.
- D. They have 7 valence electrons.
Correct answer: A
Rationale: The correct answer is A: Noble gases are non-reactive because they have a full valence shell with 8 electrons, making them stable and unlikely to form chemical bonds with other elements. Choice B is incorrect because Noble gases are known for their inertness and lack of reactivity. Choice C is incorrect because Noble gases have 8 valence electrons, which is a key characteristic that contributes to their stability. Choice D is incorrect because Noble gases have 8 valence electrons, not 7.
3. What breaks down into glucose to provide energy?
- A. Lipids
- B. Proteins
- C. Carbohydrates
- D. Nucleic acids
Correct answer: C
Rationale: Carbohydrates are broken down into glucose during digestion, providing energy for cellular processes through glycolysis and cellular respiration. Glucose is a primary source of energy for cells, and its breakdown is essential for powering various cellular activities. Lipids are broken down into fatty acids and glycerol, not glucose. Proteins are broken down into amino acids and are not a direct source of glucose. Nucleic acids are not broken down into glucose for energy production.
4. 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.
5. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?
- A. Wheezing
- B. Difficulty breathing
- C. Chest tightness
- D. Fever
Correct answer: D
Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.
