1. What is the primary function of the large intestine?
- A. To digest food
- B. To absorb water and form feces
- C. To absorb proteins
- D. To regulate blood pressure
Correct answer: B
Rationale: The correct answer is B. The primary function of the large intestine is to absorb water from digested food and form feces for elimination. It does not primarily digest food, absorb proteins, or regulate blood pressure. Choice A is incorrect because the large intestine does not digest food but rather absorbs nutrients and water. Choice C is incorrect as the absorption of proteins primarily occurs in the small intestine. Choice D is incorrect as the regulation of blood pressure is not a primary function of the large intestine.
2. What is the term for a solution that has exactly the same concentration of solute as another solution?
- A. Saturated solution
- B. Unsaturated solution
- C. Isotonic solution
- D. Concentrated solution
Correct answer: C
Rationale: An isotonic solution is a solution that has the same concentration of solute as another solution. When cells are placed in an isotonic solution, there is no net movement of water across the cell membrane, maintaining equilibrium. Choice A, a saturated solution, refers to a solution that contains the maximum amount of solute that can be dissolved at a given temperature. Choice B, an unsaturated solution, is a solution that contains less solute than a saturated solution under the same conditions. Choice D, a concentrated solution, is a solution with a high amount of solute compared to the solvent.
3. Which form of energy is associated with the motion of an object?
- A. Kinetic energy
- B. Potential energy
- C. Thermal energy
- D. Electrical energy
Correct answer: A
Rationale: Kinetic energy is the form of energy associated with the motion of an object. When an object is in motion, it possesses kinetic energy due to its movement. Potential energy, on the other hand, is stored energy that an object has due to its position or condition. Thermal energy is related to heat, while electrical energy is associated with the flow of electric charge. In this case, the correct answer is kinetic energy as it directly correlates with the motion of an object.
4. How is work defined in terms of force and displacement?
- A. Work is the product of force and displacement in any direction
- B. Work is done only when the displacement is vertical
- C. Work is done only when the force and displacement are perpendicular
- D. Work is the product of force and displacement in the direction of the force
Correct answer: D
Rationale: Work is defined as the product of the force applied on an object and the displacement of the object in the direction of the force. This means that work is only done when the force and displacement are in the same direction. If the force and displacement are not in the same direction, only the component of the force in the direction of the displacement contributes to the work done. Therefore, choice D correctly defines work in terms of force and displacement. Choices A, B, and C are incorrect because work is specifically calculated based on the force and displacement in the direction of the force, not in any direction, only when the displacement is vertical, or when the force and displacement are perpendicular.
5. Which of the following organs is NOT directly involved in urine production?
- A. Kidneys
- B. Urethra
- C. Lungs
- D. Bladder
Correct answer: B
Rationale: The correct answer is B, Urethra. The urethra is not directly involved in urine production. It is a tube that carries urine from the bladder to the outside of the body. The kidneys are responsible for filtering waste and excess substances from the blood to produce urine. The bladder stores urine until it is expelled from the body. The lungs are not involved in urine production; they are responsible for gas exchange during respiration. Choice A, Kidneys, is directly involved in urine production by filtering the blood to form urine. Choice C, Lungs, plays a role in respiration and oxygen exchange but is not directly involved in urine production. Choice D, Bladder, stores urine before it is excreted from the body and is directly involved in the final stages of urine elimination, unlike the urethra.
