Reading
1. The final sentence suggests that public discourse about AI should focus on
- A. Celebrating the achievements of AI and promoting its widespread adoption in all sectors.
- B. Criticizing the ethical shortcomings of existing AI systems and demanding stricter regulations.
- C. Engaging in open and informed discussions about the potential benefits, risks, and responsible development of AI.
- D. Focusing solely on the technical challenges of AI development and leaving ethical considerations to experts.
Correct answer: C
Rationale: The emphasis on "ongoing public discourse" and "the future of AI in society" suggests a call for open discussions and collective responsibility, aligning with C.
2. During normal breathing, which muscle is the primary driver of inhalation by contracting and flattening to increase the volume of the thoracic cavity?
- A. Diaphragm
- B. Intercostal muscles
- C. Abdominal muscles
- D. Pectoral muscles
Correct answer: A
Rationale: The diaphragm is the primary muscle responsible for inhalation during normal breathing. When the diaphragm contracts and flattens, it increases the volume of the thoracic cavity, creating a negative pressure that allows air to rush into the lungs. The intercostal muscles also play a role in expanding the ribcage to assist with inhalation. However, the diaphragm is the main driver of the breathing process by creating the necessary space for the lungs to expand and fill with air.
3. What is the term for a group of organisms that can interbreed and produce fertile offspring?
- A. Genus
- B. Phylum
- C. Kingdom
- D. Species
Correct answer: D
Rationale: Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. In contrast, a genus (option A) is a taxonomic rank that includes one or more species that are closely related, while a phylum (option B) and a kingdom (option C) are higher taxonomic ranks that encompass multiple species.
4. Identify the direct object in the following sentence: "She baked a delicious cake for the party."
- A. for the party
- B. delicious
- C. cake
- D. baked
Correct answer: C
Rationale: The direct object receives the action of the verb.
5. Lysosomes are known as "suicide bags" of the cell. What enzymes do they contain?
- A. Hydrolytic enzymes
- B. Ligases (bonding enzymes)
- C. Transferases (molecule transfer)
- D. Oxidoreductases (redox reactions)
Correct answer: A
Rationale: Lysosomes are membrane-bound organelles containing hydrolytic enzymes responsible for breaking down various macromolecules, cellular waste, and foreign substances. These enzymes perform hydrolysis, a process where water molecules are used to break down larger molecules into smaller components. This function earned lysosomes the nickname 'suicide bags' as they can initiate cell death (apoptosis) by releasing their enzymes when needed. Ligases, transferases, and oxidoreductases are enzymes with different functions such as forming bonds, transferring molecules, and catalyzing redox reactions, respectively, which are not typically found in lysosomes. Therefore, the correct answer is A: 'Hydrolytic enzymes.'
6. Which structure helps regulate body temperature by constricting or dilating in response to temperature changes?
- A. Sebaceous glands
- B. Hair follicles
- C. Sweat glands
- D. Langerhans cells
Correct answer: C
Rationale: The correct answer is C: Sweat glands. Sweat glands play a crucial role in regulating body temperature by producing sweat that evaporates from the skin surface, cooling the body when it's hot. Sweat glands can constrict to reduce sweating in cooler temperatures and dilate to increase sweating when the body needs to cool down. Sebaceous glands are responsible for producing oil to lubricate the skin and hair follicles help in hair growth. Langerhans cells are immune cells in the skin. Therefore, sweat glands are the structure specifically involved in regulating body temperature through constriction and dilation in response to temperature changes.
