TEAS Test 7 science quizlet

1. Why is warming up before exercise important?

A. To prevent dehydration
B. To prevent muscle soreness
C. To prevent increased heart rate
D. To prevent low blood sugar

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. What is the function of the alveoli in the lungs?

A. To exchange carbon dioxide for oxygen
B. To transport air to the lungs
C. To filter blood
D. To produce mucus

Correct answer: A

Rationale: The corrected answer is A: 'To exchange carbon dioxide for oxygen.' The alveoli in the lungs are responsible for facilitating gas exchange, where oxygen from inhaled air diffuses into the bloodstream, and carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. This process is vital for respiration and maintaining proper oxygen levels in the body. Choices B, C, and D are incorrect. Choice B is incorrect because the alveoli are not involved in transporting air to the lungs; they are primarily responsible for gas exchange. Choice C is incorrect because the alveoli do not filter blood; their main function is gas exchange. Choice D is incorrect because alveoli do not produce mucus; mucus is produced by other specialized cells in the respiratory system.

4. Which of the following words, as used in the timeline, indicates the chronology of events in Barton's life?

A. Front
B. First
C. After
D. Through

Correct answer: C

Rationale: 'After' is used to indicate that one event happened following another in time. In the context of a timeline, 'After' signifies the sequence of events, showing what occurred subsequent to a particular point in time. In the provided extract, events unfold in a specific order, with each event happening 'after' the previous one. Choices A, B, and D do not inherently convey the idea of chronological order and are not suitable for indicating the sequence of events in a timeline.

5. Which of the following events occurred fourth on the timeline?

A. Helped found the National Geographic Society
B. Developed a metal detector
C. Moved to Canada
D. Started a school for the deaf

Correct answer: D

Rationale: The event that occurred fourth on the timeline was starting a school for the deaf. Looking at the provided extract, we can see that the order is significant when discussing a timeline. Out of the given events, founding a school for the deaf would come fourth in chronological order. 'Helped found National Geographic Society,' 'Developed a metal detector,' and 'Moved to Canada' would precede starting a school for the deaf in a chronological timeline, making them incorrect choices.
