Reading
1. The author's attitude towards history seems to be
- A. indifferent and neutral, presenting it as an objective field of study.
- B. critical and dismissive, questioning its practical applicability in the present.
- C. enthusiastic and optimistic, highlighting its potential to guide the future.
- D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.
Correct answer: C
Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.
2. A solution is considered saturated when...
- A. More solute can be dissolved
- B. The solvent starts to evaporate
- C. The solution becomes cloudy
- D. It reaches a specific temperature
Correct answer: B
Rationale: The correct answer is B: 'The solvent starts to evaporate.' A solution is considered saturated when the solvent can no longer dissolve any more solute at a given temperature. When the solvent starts to evaporate, it means that the solution is becoming more concentrated and reaching its saturation point. This is a key indicator of a saturated solution. The other options do not accurately describe the concept of a saturated solution, making them incorrect choices.
3. Which type of cell is responsible for carrying oxygen throughout the body?
- A. Nerve cell
- B. Muscle cell
- C. Skin cell
- D. Red blood cell
Correct answer: D
Rationale: The correct answer is D: Red blood cell. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues and organs. Nerve cells (option A) transmit electrical signals, muscle cells (option B) are involved in movement, and skin cells (option C) form the outer layer of the skin and provide protection.
4. The process by which a cell divides to produce two daughter cells is called:
- A. Mitosis
- B. Meiosis
- C. Differentiation
- D. Transformation
Correct answer: A
Rationale: The correct answer is A: "Mitosis." Mitosis is the process of cell division in which a cell duplicates its chromosomes and divides into two identical daughter cells. This is a crucial mechanism for growth, repair, and maintenance of multicellular organisms. Meiosis (option B) is a different type of cell division that produces gametes with half the number of chromosomes. Differentiation (option C) refers to the process by which cells become specialized for specific functions. Transformation (option D) is a term used in molecular biology to describe the uptake of foreign DNA by a cell. In this question, the specific process of cell division leading to the production of two daughter cells aligns with mitosis.
5. What is the relationship between genetic drift and the founder effect?
- A. Founder effect is a cause of genetic drift within a small population
- B. Genetic drift is a cause of the founder effect in new populations
- C. They are the same phenomenon with different names
- D. They are unrelated concepts.
Correct answer: A
Rationale: Rationale: - The founder effect is a specific type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation. - Genetic drift, on the other hand, is a broader concept that refers to random changes in allele frequencies in a population over time due to chance events. - Therefore, the founder effect is a specific scenario within the broader concept of genetic drift, where the establishment of a new population by a small number of individuals leads to genetic changes in the population.
6. Which sentence uses the gerund (-ing) form correctly?
- A. My favorite activity is playing tennis.
- B. He enjoys to travel to new places.
- C. Reading a good book is relaxing.
- D. Writing is her passion.
Correct answer: A
Rationale: Option A uses the gerund as the direct object of "is," while the other options lack a clear function for the -ing form.
