1. What is the tough, fibrous tissue that connects bones at joints called?
- A. Cartilage
- B. Ligaments
- C. Tendons
- D. Fascia
Correct answer: B
Rationale: The correct answer is B: Ligaments. Ligaments are the tough, fibrous tissue that connects bones at joints. They provide stability and support to the joints, preventing excessive movement that could result in injury. Cartilage is a smooth, rubbery tissue that covers the ends of bones and cushions joints. Tendons are fibrous cords that attach muscles to bones, allowing for movement. Fascia is a connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, providing support and protection. Therefore, in this case, the term that specifically refers to the tissue connecting bones at joints is ligaments.
2. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 → 2NH3?
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer: a
Rationale: The coefficient of N2 is 1 in the balanced equation
3. A guitar string vibrates at a fundamental frequency of 440 Hz. What is the frequency of the second harmonic (first overtone)?
- A. 220 Hz
- B. 440 Hz
- C. 880 Hz
- D. 1760 Hz
Correct answer: C
Rationale: Harmonics have frequencies that are multiples of the fundamental frequency. The second harmonic has a frequency twice the fundamental, so it's 440 Hz * 2 = 880 Hz.
4. Which sentence uses the modal verb "should" correctly?
- A. You should have studied harder for the exam.
- B. I should be going now.
- C. She said she should have taken a different route.
- D. They should be arriving any minute now.
Correct answer: B
Rationale: Option B conveys an intention or expectation regarding the present or near future.
5. What is the process of breaking down fatty acids into acetyl-CoA, a key molecule in cellular respiration, called?
- A. Beta-oxidation
- B. Lipolysis
- C. Carbohydrate catabolism
- D. Nucleic acid catabolism
Correct answer: A
Rationale: Rationale: A) Beta-oxidation is the process of breaking down fatty acids into acetyl-CoA molecules. This process occurs in the mitochondria and is a crucial step in fatty acid metabolism for energy production. B) Lipolysis is the breakdown of fats into fatty acids and glycerol, but it does not specifically refer to the conversion of fatty acids into acetyl-CoA. C) Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production and is not directly related to the conversion of fatty acids into acetyl-CoA. D) Nucleic acid catabolism refers to the breakdown of nucleic acids into nucleotides and does not involve the conversion of fatty acids into acetyl-CoA.
6. Which additional information would be MOST relevant to the topic of the passage?
- A. A detailed history of the development of specific social media platforms.
- B. Studies on the psychological effects of prolonged social media use on teenagers.
- C. Statistics on the global economic impact of the social media industry.
- D. Technical explanations of the algorithms used by social media platforms.
Correct answer: B
Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.
