1. How does polarization affect the intensity of light passing through a polarizing filter?
- A. All light passes through regardless of polarization.
- B. Light with the same polarization as the filter passes through, while others are blocked
- C. Light with higher intensity passes through, while weaker light is blocked.
- D. The intensity is reduced for all light, regardless of polarization.
Correct answer: B
Rationale: A polarizing filter only allows light waves with a specific polarization direction to pass through, reducing the intensity of waves with different orientations.
2. What is the measure of the total amount of space occupied by an object?
- A. Mass
- B. Density
- C. Weight
- D. Volume
Correct answer: d
Rationale: Volume is the measure of the total amount of space occupied by an object and is typically measured in cubic units such as cubic meters or liters.
3. The number of protons in an atom is determined by its:
- A. Atomic mass
- B. Electron configuration
- C. Chemical properties
- D. Atomic number
Correct answer: C
Rationale: Atomic number is a fundamental property of an element and is independent of its mass, electron configuration, or chemical behavior.
4. The muscular tube that carries urine from the kidneys to the bladder is called the:
- A. Nephron
- B. Ureter
- C. Urethra
- D. Glomerulus
Correct answer: B
Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.
5. Histamine, released during an allergic reaction, causes symptoms like:
- A. Fever and fatigue
- B. Runny nose and itchiness
- C. Muscle aches and joint pain
- D. Cough and shortness of breath
Correct answer: B
Rationale: The correct answer is B: 'Runny nose and itchiness.' Histamine is a chemical released by the body during an allergic reaction. It causes various symptoms such as itching, sneezing, runny nose, and watery eyes. These symptoms are commonly associated with allergic reactions like hay fever or hives. Fever and fatigue (option A) are not directly caused by histamine release. Muscle aches and joint pain (option C) are not typical symptoms of histamine release during an allergic reaction. Cough and shortness of breath (option D) are more commonly associated with asthma or respiratory allergies rather than histamine release.
6. What is the term for a solution that contains the maximum amount of solute that can dissolve at a specific temperature and pressure?
- A. Saturated solution
- B. Unsaturated solution
- C. Dilute solution
- D. Concentrated solution
Correct answer: A
Rationale: A saturated solution is one in which the maximum amount of solute has dissolved under specific conditions. The other choices do not accurately describe a saturated solution.
