ATI TEAS 7
Reading
1. The author's attitude towards history seems to be
- A. indifferent and neutral, presenting it as an objective field of study.
- B. critical and dismissive, questioning its practical applicability in the present.
- C. enthusiastic and optimistic, highlighting its potential to guide the future.
- D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.
Correct answer: C
Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.
2. What is the relationship between work and the displacement of an object?
- A. Work depends only on the force applied, not displacement
- B. Work is directly proportional to displacement
- C. Work is inversely proportional to displacement
- D. Work is unrelated to displacement
Correct answer:
Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.
3. Maintaining good muscle strength and flexibility as we age becomes important to avoid:
- A. Headaches
- B. Falls
- C. Anxiety
- D. Common cold
Correct answer: B
Rationale: The correct answer is B: 'Falls.' Maintaining good muscle strength and flexibility as we age is crucial for preventing falls, which become more common with age and can lead to serious injuries such as fractures. Strong muscles and good flexibility help in maintaining balance and stability, reducing the risk of falls. Headaches, anxiety, and the common cold are not directly related to muscle strength and flexibility, making them less likely to be avoided by focusing on these aspects of physical health.
4. What term describes the phenomenon of two waves canceling each other out when they meet?
- A. Refraction
- B. Diffraction
- C. Destructive interference
- D. Constructive interference
Correct answer: C
Rationale: Destructive interference occurs when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction and diffraction are phenomena related to the bending of waves as they pass through different mediums or obstacles, respectively.
5. Which of the following is the main function of the pancreas?
- A. To store food and break it down into smaller pieces
- B. To absorb nutrients into the bloodstream
- C. To produce enzymes that help digest food
- D. To regulate blood sugar levels
Correct answer: C
Rationale: Rationale: The pancreas is a vital organ in the digestive system that produces digestive enzymes such as amylase, lipase, and proteases. These enzymes are released into the small intestine to help break down carbohydrates, fats, and proteins in food, aiding in the digestion and absorption of nutrients. Options A and B are incorrect because the pancreas is not involved in storing or absorbing nutrients. Option D is partially correct as the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, but its primary function is to produce digestive enzymes.
6. Muscles that work together to produce a specific movement are called
- A. Antagonistic muscles
- B. Agonistic muscles
- C. Synergistic muscles
- D. Flexors and extensors
Correct answer: C
Rationale: Synergistic muscles are the correct answer because they are muscles that work together to produce a specific movement. These muscles coordinate their actions to achieve a common goal, such as bending the elbow or extending the knee. Antagonistic muscles work in opposition to each other, while agonistic muscles are the primary movers in a particular movement. Flexors and extensors refer to specific muscle groups that perform opposing actions, rather than working together synergistically. Understanding the concept of synergistic muscles is essential in biomechanics and exercise science.
