1. What is the significance of cell division?
- A. Growth and repair of tissues
- B. Sexual reproduction
- C. Genetic diversity
- D. All of the above
Correct answer: D
Rationale: Cell division is a fundamental process that serves multiple critical functions in living organisms. It is essential for the growth and repair of tissues by enabling the formation of new cells to replace old or damaged ones. Moreover, cell division plays a pivotal role in sexual reproduction as it is involved in the production of gametes necessary for fertilization. Additionally, cell division contributes to genetic diversity through processes like meiosis, which leads to the formation of genetically distinct gametes. Therefore, the correct answer is D, 'All of the above,' as cell division is significant for growth, repair, sexual reproduction, and genetic diversity. Choices A, B, and C are incorrect because they each represent only one aspect of the significance of cell division, whereas the correct answer encompasses all the essential roles that cell division plays in living organisms.
2. Which of the following best describes the statement 'This flower is dead; someone must have forgotten to water it'?
- A. A classification
- B. An observation
- C. An inference
- D. A collection
Correct answer: C
Rationale: The correct answer is 'C: An inference.' An inference is a conclusion reached based on evidence and reasoning. In this statement, the conclusion that someone must have forgotten to water the flower is drawn from the evidence that the flower is dead. Choice A, 'A classification,' is incorrect because the statement does not involve categorizing or grouping. Choice B, 'An observation,' is incorrect as the statement goes beyond just stating a fact and makes a conclusion. Choice D, 'A collection,' is unrelated to the process of drawing a conclusion based on the given evidence.
3. Which of the following statements is true about Noble gases?
- A. They are non-reactive.
- B. They are highly reactive.
- C. They have 8 valence electrons.
- D. They have 7 valence electrons.
Correct answer: A
Rationale: The correct answer is A: Noble gases are non-reactive because they have a full valence shell with 8 electrons, making them stable and unlikely to form chemical bonds with other elements. Choice B is incorrect because Noble gases are known for their inertness and lack of reactivity. Choice C is incorrect because Noble gases have 8 valence electrons, which is a key characteristic that contributes to their stability. Choice D is incorrect because Noble gases have 8 valence electrons, not 7.
4. The Minimum Inhibitory Concentration (MIC) of an antibiotic refers to:
- A. The lowest concentration that kills bacteria
- B. The dose required for 50% bacterial inhibition
- C. The time it takes for an antibiotic to work
- D. The spectrum of bacteria the antibiotic targets
Correct answer: B
Rationale: A) The lowest concentration that kills bacteria is known as the Minimum Bactericidal Concentration (MBC), not the Minimum Inhibitory Concentration (MIC). MIC is the lowest concentration of an antibiotic that inhibits visible growth of bacteria. B) The MIC of an antibiotic is the concentration at which bacterial growth is inhibited by 50%. This concentration is used to determine the effectiveness of an antibiotic against a specific bacterium. C) The time it takes for an antibiotic to work is not described by the MIC. MIC is a measure of concentration, not time. D) The spectrum of bacteria the antibiotic targets is not defined by the MIC. The MIC value is specific to a particular antibiotic and bacterium, regardless of the spectrum of activity of the antibiotic.
5. 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.
