1. Which skin condition is characterized by patches of inflamed, reddened skin and is often triggered by allergens or stress?
- A. Eczema
- B. Psoriasis
- C. Acne
- D. Vitiligo
Correct answer: A
Rationale: The correct answer is A: Eczema. Eczema is a skin condition characterized by patches of inflamed, reddened skin that can be triggered by allergens or stress. It is a chronic condition that can cause itching and discomfort. Psoriasis (option B) is a different skin condition characterized by red, scaly patches on the skin. Acne (option C) is a common skin condition characterized by pimples and clogged pores. Vitiligo (option D) is a condition where the skin loses its pigment, resulting in white patches. Therefore, eczema best fits the description provided in the question.
2. According to the passage, learning from history can help us
- A. predict future events with complete certainty.
- B. avoid any possibility of making mistakes in the present.
- C. identify potential challenges and develop innovative solutions.
- D. directly replicate the successes of past societies in our own time.
Correct answer: C
Rationale: The passage emphasizes learning from both successes and failures, identifying potential obstacles, and using historical knowledge to create solutions for current problems.
3. Which of the following is evidence that the controlling process is effective?
- A. The things that were planned are done
- B. Physicians do not complain.
- C. Employees are contended
- D. There is an increase in customer satisfaction rate.
Correct answer: A
Rationale: The correct answer is A: 'The things that were planned are done.' This is evidence that the controlling process is effective because it indicates that the organization is able to execute its plans successfully. When planned tasks and activities are completed as intended, it shows that the controlling function is ensuring that operations are on track and that deviations are being corrected. The completion of planned tasks also demonstrates that resources are being effectively utilized and that performance is being monitored and controlled. The other options do not directly relate to the effectiveness of the controlling process. Physicians not complaining, employees being contented, and an increase in customer satisfaction rate could be influenced by various factors and may not necessarily be solely attributed to the effectiveness of the controlling process.
4. Dietary fiber, although not fully digested by the body, plays a crucial role in digestion. What is one of the main benefits of consuming sufficient dietary fiber?
- A. Provides a concentrated source of energy
- B. Aids in the absorption of vitamins and minerals
- C. Promotes satiety and gut health
- D. Breaks down complex carbohydrates
Correct answer: C
Rationale: Consuming sufficient dietary fiber promotes satiety and gut health. Fiber adds bulk to the diet, which helps you feel full and satisfied after meals, reducing overeating. Additionally, fiber helps regulate bowel movements by promoting healthy digestion and preventing constipation. It also feeds beneficial gut bacteria, supporting a healthy gut microbiome. While fiber does not provide energy like carbohydrates, it is essential for overall digestive health and can help prevent various chronic diseases.
5. In plant cells, what structure provides rigidity and support?
- A. Cell membrane
- B. Golgi apparatus
- C. Plastid
- D. Cell wall
Correct answer: D
Rationale: The correct answer is D: Cell wall. The cell wall is a rigid structure found in plant cells that provides support and protection. It is composed of cellulose and other materials, forming a tough outer layer that helps maintain the cell's shape and prevents it from bursting under pressure. The cell membrane (option A) is a semi-permeable barrier that surrounds the cell but does not provide rigidity. The Golgi apparatus (option B) is involved in sorting and packaging proteins. Plastids (option C) are organelles responsible for functions like photosynthesis and storage, but they do not provide rigidity and support like the cell wall does.
6. Which of the following is the smallest unit of matter?
- A. Molecule
- B. Atom
- C. Compound
- D. Element
Correct answer: B
Rationale: An atom is the fundamental building block of matter, while molecules are formed by the combination of atoms.
