1. Differentiate between gene therapy and genetic engineering in the context of human intervention.
- A. Gene therapy aims to modify existing genes within body cells, while genetic engineering manipulates genes in embryos to be passed on to offspring.
- B. Gene therapy focuses on treating genetic diseases, while genetic engineering enhances desirable traits or eliminates undesirable ones.
- C. Both involve directly altering the DNA sequence, but gene therapy targets somatic cells and genetic engineering modifies germline cells.
- D. There is no fundamental difference; both terms are synonymous.
Correct answer: B
Rationale: Rationale: A) Incorrect. Gene therapy does aim to modify existing genes within body cells, but genetic engineering does not necessarily manipulate genes in embryos to be passed on to offspring. Genetic engineering can involve modifying genes in any type of cell, not just embryos. B) Correct. Gene therapy is a medical intervention that aims to treat genetic diseases by correcting or replacing faulty genes within an individual's body cells. On the other hand, genetic engineering involves modifying genes to enhance specific traits or eliminate undesirable ones, often in the context of agriculture or biotechnology. C) Incorrect. While both gene therapy and genetic engineering involve altering DNA sequences, the distinction lies in the target cells. Gene therapy targets somatic cells (non-reproductive cells), while genetic engineering typically involves modifying germline cells (reproductive cells that can pass on genetic changes to offspring). D) Incorrect. There is
2. What literary device is used in the phrase "the lion's roar thundered across the savanna"?
- A. Simile
- B. Metaphor
- C. Hyperbole
- D. Personification
Correct answer: A
Rationale: Option A compares the roar to thunder using "like" or "as," making it a simile.
3. What is the basic unit of heredity?
- A. Chromosome
- B. Cell
- C. Gene
- D. Organ
Correct answer: C
Rationale: Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.
4. He discusses the goal of the department. Which of the following statements is a goal?
- A. Increase the patient satisfaction rate
- B. Eliminate the incidence of delayed administration of medications
- C. Establish rapport with patients.
- D. Reduce response time to two minutes.
Correct answer: A
Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.
5. What is the main idea of the passage?
- A. Petra is a modern city built for tourism.
- B. Petra's historical significance lies in its architectural achievements.
- C. Petra's prosperity was linked to its strategic location on trade routes.
- D. Petra's obscurity remains a mystery despite its rediscovery.
Correct answer: C
Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.
6. 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.
