Reading
1. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?
- A. It is the only viable solution to the problem and should be prioritized.
- B. It is a promising approach but requires further research and development.
- C. It is less effective than traditional methods and poses environmental risks.
- D. It is irrelevant to the problem and will not make a significant impact.
Correct answer: B
Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.
2. What is the main function of lysosomes?
- A. Breaking down and recycling cellular waste
- B. Storing carbohydrates
- C. Synthesizing lipids
- D. Transcribing DNA into mRNA
Correct answer: A
Rationale: The main function of lysosomes is to break down and recycle cellular waste. Lysosomes contain digestive enzymes that help break down old or damaged organelles, foreign substances, and cellular debris. This process, known as autophagy, helps maintain cellular health and proper functioning. Storing carbohydrates (option B) is not a function of lysosomes; carbohydrates are typically stored in the form of glycogen in the cytoplasm or as starch in plant cells. Synthesizing lipids (option C) is primarily done by the endoplasmic reticulum and not by lysosomes. Transcribing DNA into mRNA (option D) is a function of the nucleus and not the lysosomes. Therefore, the correct answer is A: breaking down and recycling cellular waste.
3. Which additional information would be MOST relevant to the topic of the passage?
- A. A detailed history of the development of specific social media platforms.
- B. Studies on the psychological effects of prolonged social media use on teenagers.
- C. Statistics on the global economic impact of the social media industry.
- D. Technical explanations of the algorithms used by social media platforms.
Correct answer: B
Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.
4. Where does fertilization, the fusion of sperm and egg, typically occur in the human body?
- A. Ovary
- B. Uterus
- C. Fallopian tube
- D. Vagina
Correct answer: C
Rationale: The correct answer is C: Fallopian tube. Fertilization, the fusion of sperm and egg, typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it may encounter sperm for fertilization. The fertilized egg then moves to the uterus for implantation and development. The ovary releases the egg but fertilization occurs in the fallopian tube, making it the correct answer.
5. Neurons, the functional units of the nervous system, belong to which tissue type?
- A. Epithelial tissue
- B. Connective tissue
- C. Muscle tissue
- D. Nervous tissue
Correct answer: D
Rationale: The correct answer is D: Nervous tissue. Neurons are specialized cells that transmit nerve impulses and are the primary components of the nervous system. Nervous tissue is made up of neurons and supporting cells called neuroglia. Neurons are responsible for processing and transmitting information throughout the body, making them a crucial part of the nervous system. Epithelial tissue (A) is primarily involved in covering and lining surfaces, connective tissue (B) supports and connects other tissues, and muscle tissue (C) is responsible for movement. Therefore, neurons belong to nervous tissue, which is specialized for communication and coordination within the body.
6. Identify the pronoun in the following sentence: She quickly finished her homework before dinner.
- A. quickly
- B. finished
- C. her
- D. before
Correct answer: C
Rationale: Pronouns take the place of nouns. "Her" replaces a specific female person's name.
