1. Which of the following is the main function of the lungs?
- A. To transport oxygen and nutrients throughout the body
- B. To coordinate movement and sensory information
- C. To filter waste products from the blood
- D. To exchange oxygen and carbon dioxide between the body and the environment
Correct answer: D
Rationale: Rationale: A) To transport oxygen and nutrients throughout the body - While the lungs do play a role in transporting oxygen, their primary function is to exchange oxygen and carbon dioxide between the body and the environment. The transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, specifically the blood vessels. B) To coordinate movement and sensory information - This function is primarily carried out by the nervous system, specifically the brain and spinal cord. C) To filter waste products from the blood - The kidneys are responsible for filtering waste products from the blood, not the lungs. The lungs primarily function in gas exchange.
2. Which of the following is a pair of nerves that originates from the brain?
- A. Spinal nerves
- B. Olfactory nerves
- C. Sciatic nerve
- D. Optic nerve
Correct answer: B
Rationale: The correct answer is B, Olfactory nerves, because they are a pair of cranial nerves that originate from the brain and are responsible for the sense of smell. Spinal nerves (option A) originate from the spinal cord, not the brain. The sciatic nerve (option C) is a large nerve that runs from the lower back down the back of each leg and also originates from the spinal cord, not the brain. The optic nerve (option D) is a cranial nerve that connects the eye to the brain, but it is not a pair of nerves that originates from the brain. Therefore, the olfactory nerves are the only pair of nerves listed that specifically originate from the brain.
3. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.
- A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer
- B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional
- C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals
- D. Ionic bonds form discrete molecules, while metallic bonds form extended structures
Correct answer: D
Rationale: Ionic bonds involve complete electron transfer between atoms, creating strong, non-directional electrostatic attraction. Metallic bonds involve a delocalized "sea" of electrons shared across all metal atoms, resulting in a strong, extended structure.
4. What is the tone of the following sentence: "The presentation was informative and engaging."
- A. Sarcastic
- B. Neutral
- C. Angry
- D. Confused
Correct answer: B
Rationale: The sentence objectively describes the presentation without expressing any specific emotions.
5. How do you spell the past participle of the verb "lie" (to recline)?
- A. lied
- B. lain
- C. lay
- D. lying
Correct answer: B
Rationale: The past participle of "lie" (to recline) is "lain," not "lied," which is the past tense.
6. What is the formula to calculate gravitational potential energy near the Earth's surface?
- A. Potential Energy=Mass×Acceleration
- B. Potential Energy=Force×Distance
- C. Potential Energy=Mass×Height×Gravity
- D. Potential Energy=Mass×Acceleration due to gravity×Height
Correct answer: d
Rationale: Gravitational potential energy near the Earth's surface is given by the formula PE = � × � × ℎ PE=m×g×h, where � m is mass, � g is acceleration due to gravity, and ℎ h is heigh
