1. Where does fertilization typically occur in the female reproductive system?
- A. uterus
- B. fallopian tube
- C. endometrium
- D. ovary
Correct answer: B
Rationale: Fertilization typically occurs in the fallopian tube, specifically in the ampulla, which is the widest part of the tube. After ovulation, the released egg travels through the fallopian tube where it may encounter sperm for fertilization to take place. The fallopian tube provides the ideal environment for fertilization due to the presence of cilia that help move the egg and sperm towards each other. The uterus is where the fertilized egg will implant and develop into a fetus, not where fertilization occurs. The endometrium is the lining of the uterus that thickens to support a potential pregnancy but is not the site of fertilization. The ovary releases the egg during ovulation but is not where fertilization occurs.
2. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?
- A. 30,000 kg m/s
- B. 1500 kg m/s
- C. 20 kg m/s
- D. Momentum cannot be determined without knowing the direction of motion.
Correct answer: A
Rationale: The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the momentum of the car can be determined using the formula momentum = mass x velocity. Substituting the given values, momentum = 1500 kg x 20 m/s = 30,000 kg m/s. Therefore, the correct answer is A, 30,000 kg m/s. Choice B (1500 kg m/s) is incorrect because that value represents the mass of the car, not its momentum. Choice C (20 kg m/s) is incorrect as it only represents the speed of the car, not its momentum. Choice D (Momentum cannot be determined without knowing the direction of motion) is incorrect because momentum is a vector quantity and can be determined using magnitude and direction, but in this case, only the magnitude is required.
3. In which direction do the particles of the medium move in a transverse wave?
- A. Perpendicular to the direction of wave travel
- B. Parallel to the direction of wave travel
- C. In a circular motion
- D. Opposite to the direction of wave travel
Correct answer: A
Rationale: In a transverse wave, the particles of the medium move perpendicular to the direction of wave travel. This means that the particles move up and down or side to side as the wave passes through the medium. This motion creates crests and troughs in the wave, leading to the characteristic oscillation observed in transverse waves. Choice B is incorrect because in transverse waves, the particle movement is not parallel to the direction of wave travel. Choice C is incorrect as the particles do not move in a circular motion in a transverse wave. Choice D is incorrect as the particles do not move opposite to the direction of wave travel; they move perpendicular to it.
4. Which of the following are the abdominal quadrants?
- A. RUQ, RLQ, LLQ, LUQ
- B. RUQ, LUQ, RLQ, LLQ
- C. LUQ, RUQ, LLQ, RLQ
- D. LLQ, LUQ, RUQ, RLQ
Correct answer: B
Rationale: The correct answer is B: RUQ, LUQ, RLQ, LLQ. The four abdominal quadrants are named as follows: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), and Left Lower Quadrant (LLQ). These quadrants are used in healthcare to describe specific areas of the abdomen during assessments and discussions related to abdominal anatomy and pathology. Choices A, C, and D are incorrect because they do not follow the standard order of the abdominal quadrants.
5. What do large intestines absorb?
- A. Water, sodium, and potassium ions
- B. Proteins and carbohydrates
- C. Water, vitamin K, and bile salts
- D. Vitamins A, D, E, K
Correct answer: C
Rationale: The correct answer is C. The large intestine absorbs water, vitamin K, bile salts, sodium, and chloride ions. It helps in maintaining the body's water and electrolyte balance, and also plays a role in absorbing certain vitamins and nutrients such as vitamin K. Choices A, B, and D are incorrect because proteins, carbohydrates, vitamins A, D, E, and K are primarily absorbed in the small intestine, not the large intestine.
