Reading
1. The passage implies that achieving energy sustainability requires...
- A. solely relying on renewable energy sources for electricity generation.
- B. a combination of advancements in renewable energy production and management technologies.
- C. prioritizing economic benefits over environmental concerns when making energy choices.
- D. focusing solely on reducing energy consumption without addressing production sources.
Correct answer: B
Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.
2. What is the term for the small air sacs in the lungs where gas exchange (oxygen and carbon dioxide) takes place?
- A. Bronchi
- B. Alveoli
- C. Trachea
- D. Bronchioles
Correct answer: B
Rationale: The correct answer is B: Alveoli. Alveoli are the small air sacs in the lungs where gas exchange occurs. Oxygen from the air we breathe diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. Bronchi (A) are the large airways that branch off the trachea (C) and lead into the lungs. Bronchioles (D) are smaller airways that branch off the bronchi. Understanding the structure and function of the respiratory system is important for comprehending how oxygen is taken in and carbon dioxide is removed from the body.
3. A news article claims a scientist has discovered a cure for cancer. How should you approach this information?
- A. Celebrate the breakthrough and immediately share the news with everyone.
- B. Remain skeptical and wait for independent verification and further research.
- C. Dismiss the claim as impossible without any further investigation.
- D. Accept the information as fact because it was published in a news article.
Correct answer: B
Rationale: Extraordinary claims require extraordinary evidence. It's essential to wait for scientific consensus and verification before accepting such groundbreaking claims.
4. A new drug successfully treats a disease in mice. This suggests the drug will also be effective in humans. True or False? False. Animal models don't always perfectly translate to humans due to biological differences. Further testing in humans is crucial before drawing conclusions about safety and efficacy. A conclusion based on scientific evidence should be:
- A. Unquestionable and accepted by all scientists.
- B. Open to revision and further testing as new evidence emerges.
- C. Based solely on expert opinions and authority figures.
- D. Always presented as absolute truth with no room for doubt.
Correct answer: B
Rationale: Scientific conclusions should always be open to revision and further testing as new evidence emerges. Science is a dynamic process that involves continuous questioning, testing, and refining of ideas based on the most current evidence available. It is essential to remain open-minded and willing to adjust conclusions in light of new information to ensure the most accurate and reliable understanding of the natural world.
5. The two main divisions of the skeletal system are:
- A. Upper and lower body bones
- B. Axial and appendicular skeleton
- C. Long and short bones
- D. Compact and spongy bone
Correct answer: B
Rationale: The correct answer is B: Axial and appendicular skeleton. The skeletal system is divided into two main parts: the axial skeleton, which includes the skull, rib cage, and vertebral column, and the appendicular skeleton, which includes the bones of the arms, legs, shoulders, and hips. This division is based on the location and function of the bones in the body. The other options are incorrect as they do not represent the main divisions of the skeletal system. Understanding these divisions is important for studying the structure and function of the human skeletal system.
6. What is a lifestyle practice that can benefit the lymphatic system?
- A. Consuming a high-sugar diet
- B. Maintaining a sedentary lifestyle
- C. Regularly engaging in moderate exercise
- D. Smoking cigarettes
Correct answer: C
Rationale: The correct answer is C: Regularly engaging in moderate exercise. Exercise can benefit the lymphatic system by promoting circulation and the movement of lymph fluid throughout the body. This helps to remove toxins and waste products, improving overall lymphatic function. Consuming a high-sugar diet (A) can have a negative impact on the lymphatic system by increasing inflammation and impairing immune function. Maintaining a sedentary lifestyle (B) can lead to poor lymphatic circulation and fluid retention. Smoking cigarettes (D) is harmful to the lymphatic system and overall health, as it can impair immune function and increase inflammation.
