TEAS Test 7 science quizlet

1. Why is warming up before exercise important?

Correct answer: B

Rationale: Warming up before exercise is crucial to prevent muscle soreness. It helps by increasing blood flow to the muscles, improving flexibility, and preparing the body for physical activity. Dehydration, increased heart rate, and low blood sugar are not directly prevented by warming up before exercise. Dehydration is prevented by proper hydration before and during exercise; increased heart rate is a normal physiological response to exercise; and low blood sugar is managed through proper nutrition and timing of meals before physical activity.

2. Which cavity contains all of the frontal cavities? Choose only ONE best answer.

Correct answer: D

Rationale: The correct answer is D: Ventral. The ventral cavity includes both the thoracic and abdominopelvic cavities. The frontal cavities are part of the ventral cavity, which is located towards the front of the body, while the dorsal cavity is towards the back. The dorsal cavity contains the cranial and vertebral cavities, not the frontal cavities. The thoracic cavity is part of the ventral cavity but does not encompass all the frontal cavities. The abdominopelvic cavity is also part of the ventral cavity, but it does not include all of the frontal cavities. Therefore, the ventral cavity is the correct choice as it encompasses all the frontal cavities.

3. Where is pseudostratified columnar epithelium primarily found?

Correct answer: C

Rationale: Pseudostratified columnar epithelium is a type of epithelial tissue found in the respiratory tract, including the lining of the trachea and bronchi. It is also found in the male reproductive system and parts of the auditory tube and external ear canal. Among the options provided, the external ears (option C) are the most relevant location for pseudostratified columnar epithelium. Skeletal muscle (option A) is primarily composed of muscle fibers, not epithelial tissue. The bony skeleton (option B) is composed of bone tissue. The bloodstream (option D) consists of blood cells and plasma, not epithelial tissue.

4. How does an increase in mass affect the force required to produce the same acceleration on an object?

Correct answer: A

Rationale: The correct answer is A, 'Increases force required.' According to Newton's second law of motion, force is directly proportional to mass and acceleration (F = ma). Therefore, an increase in mass will require an increase in force to produce the same acceleration on an object. Choice B is incorrect because an increase in mass does not decrease the force required; it increases it. Choice C is incorrect as increasing mass does affect the force required. Choice D is incorrect as the relationship between mass and force is predictable according to Newton's laws of motion.

5. Which factor most significantly affects the kinetic energy of an object?

Correct answer: B

Rationale: Kinetic energy is directly proportional to the square of an object's velocity. This means that changes in velocity have a greater impact on the kinetic energy of an object compared to changes in mass, displacement, or potential energy. The mass of an object affects its kinetic energy, but the effect is linear, not squared like velocity. Displacement does not directly affect kinetic energy, as it is a measure of the change in position, not related to motion. Potential energy is a different form of energy and is not directly related to the kinetic energy of an object. Therefore, the velocity of an object has the most significant effect on its kinetic energy.
