Anatomy
1. Cystitis is an inflammation of the:
- A. Kidneys
- B. Bladder
- C. Ureters
- D. Urethra
Correct answer: B
Rationale: The correct answer is B: Bladder. Cystitis is an inflammation of the bladder, typically caused by a bacterial infection. Symptoms include frequent and urgent urination, along with pain or discomfort in the pelvic area. The kidneys (option A) are responsible for filtering blood and producing urine, but they are not the site of inflammation in cystitis. The ureters (option C) are the tubes that connect the kidneys to the bladder and are not typically affected by cystitis. The urethra (option D) is the tube that carries urine from the bladder out of the body, but it is not where the inflammation occurs in cystitis.
2. Antibiotic resistance in bacteria is an example of:
- A. Convergent evolution
- B. Divergent evolution
- C. Microevolution
- D. Macroevolution
Correct answer: C
Rationale: Rationale: - Convergent evolution (option A) refers to the process by which different species evolve similar traits independently in response to similar environmental pressures. Antibiotic resistance in bacteria does not involve different species evolving similar traits. - Divergent evolution (option B) refers to the process by which two or more related species become more dissimilar over time. Antibiotic resistance in bacteria does not involve related species becoming more dissimilar. - Microevolution (option C) refers to changes in allele frequencies within a population over a relatively short period of time. Antibiotic resistance in bacteria is a classic example of microevolution, where bacteria evolve resistance to antibiotics through the natural selection of pre-existing resistant strains. - Macroevolution (option D) refers to large-scale evolutionary changes that result in the formation of new species or higher taxonomic groups. Antibiotic resistance in bacteria does not involve
3. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?
- A. Limiting high-sodium foods in the diet
- B. Consuming adequate amounts of cranberry juice
- C. Holding urine in the bladder for long periods
- D. Getting regular moderate-intensity exercise
Correct answer: C
Rationale: The correct answer is C: Holding urine in the bladder for long periods. This is not recommended for optimal urinary system health because it can increase the risk of urinary tract infections and bladder problems. It is important to empty the bladder regularly to prevent bacteria from multiplying and causing infections. Limiting high-sodium foods in the diet helps maintain kidney health by reducing the risk of kidney stones and high blood pressure. Consuming cranberry juice can help prevent urinary tract infections due to its antibacterial properties. Regular moderate-intensity exercise promotes overall health, including good circulation to the kidneys and bladder.
4. According to the Law of Conservation of Energy, the total amount of energy in a closed system:
- A. Increases over time.
- B. Decreases over time.
- C. Remains constant.
- D. Depends on the temperature of the system.
Correct answer: C
Rationale: Rationale: According to the Law of Conservation of Energy, the total amount of energy in a closed system remains constant. This means that energy cannot be created or destroyed within the system, but can only be transformed from one form to another. As a result, the total energy within the system is conserved and does not change over time. This principle is fundamental in understanding energy transformations and interactions within physical systems.
5. What is the meaning of the idiom "to cross that bridge when we come to it"?
- A. To deal with a problem immediately
- B. To plan for the future in detail
- C. To worry about potential problems prematurely
- D. To avoid difficult situations
Correct answer: C
Rationale: The idiom suggests dealing with challenges as they arise, not before.
6. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?
- A. 0.5 m/s²
- B. 1 m/s²
- C. 2 m/s²
- D. 10 m/s²
Correct answer: C
Rationale: Use Newton's second law, F = ma, where F is the net force, m is the mass, and a is the acceleration. Since there is no friction, the net force equals the applied force (20 N). Therefore, a = F/m = 20 N / 10 kg ≈ 2 m/s².
