TEAS 7 science practice questions
1. Differentiate between epithelial and connective tissue.
- A. Epithelial tissue lines surfaces and glands, while connective tissue supports tendons.
- B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
- C. Epithelial tissue covers surfaces and connective tissue supports muscle contraction.
- D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.
Correct answer: B
Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ. Epithelial tissue acts as a barrier to protect underlying tissues and organs, while connective tissue connects, supports, and separates different types of tissues and organs in the body. Choice A is incorrect as connective tissue supports and binds other tissues, not just tendons. Choice C is incorrect because connective tissue does not support muscle contraction; it provides support to various structures in the body. Choice D is incorrect as the size of a tissue type does not define its function; epithelial tissue and connective tissue serve different purposes in the body.
2. What is the formula to calculate work?
- A. Work = Force × Distance
- B. Work = Mass × Velocity
- C. Work = Power × Time
- D. Work = Energy ÷ Time
Correct answer: A
Rationale: Work is defined as the product of the force applied to an object and the distance over which the force is applied. The formula to calculate work is represented by Work = Force × Distance, where force is the applied force on an object and distance is the displacement over which the force is applied. Therefore, the correct formula to calculate work is Work = Force × Distance. Choice B, 'Work = Mass × Velocity,' is incorrect because work involves force and distance, not mass and velocity. Choice C, 'Work = Power × Time,' is incorrect because work is not directly calculated using power and time. Choice D, 'Work = Energy ÷ Time,' is incorrect because work is not typically calculated by dividing energy by time; rather, it involves the product of force and distance.
3. What happens during expiration?
- A. The diaphragm contracts and the thoracic cavity expands.
- B. The diaphragm relaxes and the thoracic cavity contracts.
- C. The thoracic cavity expands, increasing pressure.
- D. The diaphragm relaxes and moves upward.
Correct answer: B
Rationale: The correct answer is B. During expiration, the diaphragm relaxes, causing the thoracic cavity to contract. As the thoracic cavity decreases in size, the pressure inside the lungs increases, leading to air flowing out of the lungs. This process helps to expel carbon dioxide-rich air from the body. Choices A, C, and D are incorrect. In choice A, the diaphragm contracting and the thoracic cavity expanding describes inspiration, not expiration. Choice C is incorrect because during expiration, the thoracic cavity actually decreases in size. Choice D is incorrect as the diaphragm moving upward is not a typical movement associated with expiration.
4. What does the author imply will happen if people do not follow his suggestions?
- A. The author implies we will run out of resources in the next 10 years.
- B. The author implies water and energy prices will rise sharply in the near future.
- C. The author implies global warming and the depletion of natural resources will continue.
- D. The author implies local farmers will lose their farms.
Correct answer: C
Rationale: The author implies that neglecting the recommended actions will lead to the continued degradation of the environment and depletion of resources. The passage emphasizes the importance of being proactive in conserving resources to combat global warming and the depletion of natural resources. Choice A is incorrect because the author doesn't specify a timeframe for running out of resources. Choice B is incorrect as the focus is on environmental impact rather than economic consequences. Choice D is incorrect as the passage does not specifically mention the impact on local farmers.
5. What is the square root of 1296?
- A. 24
- B. 36
- C. 31
- D. 12
Correct answer: B
Rationale: The square root of 1296 is 36 because 36 multiplied by 36 equals 1296. Therefore, the correct answer is 36. Choices A, C, and D are incorrect. A (24) is not the square root of 1296 because 24 multiplied by 24 is 576, not 1296. C (31) is also incorrect as 31 multiplied by 31 is 961, not 1296. D (12) is not the square root of 1296 as 12 multiplied by 12 equals 144, not 1296.
