Reading
1. Based on the passage, the author most likely believes that
- A. Individual actions are insignificant in addressing climate change, and only large-scale initiatives matter.
- B. Adaptation to the changing climate is impossible, and societal collapse is inevitable.
- C. Transitioning to renewable energy and sustainable practices offers hope for mitigating climate change.
- D. The scientific evidence for climate change is unreliable, and further research is needed before taking action.
Correct answer: C
Rationale: The focus on global efforts, renewable energy, and sustainable practices suggests an optimistic outlook on mitigating climate change, aligning with C.
2. Which of the following is NOT a function of the integumentary system?
- A. Regulation of body temperature
- B. Protection from pathogens
- C. Synthesis of vitamin D
- D. Production of digestive enzymes
Correct answer: D
Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.
3. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?
- A. Both potential and kinetic energy are zero.
- B. Potential energy is maximum and kinetic energy is minimum.
- C. Potential energy is minimum and kinetic energy is maximum.
- D. Both potential and kinetic energy remain constant.
Correct answer: B
Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.
4. Myelin sheath, a fatty substance, insulates nerve fibers. What type of tissue is the myelin sheath derived from?
- A. Epithelial tissue
- B. Muscle tissue
- C. Nervous tissue (glial cells)
- D. Connective tissue
Correct answer: C
Rationale: The myelin sheath is derived from nervous tissue, specifically from glial cells, which are non-neuronal cells that support and protect neurons in the nervous system. Glial cells, such as Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, produce the myelin sheath to insulate nerve fibers and enhance the speed of nerve impulse conduction. Epithelial tissue forms the protective covering of internal and external surfaces, muscle tissue is responsible for movement, and connective tissue provides support and structure to the body. Therefore, the correct answer is C: Nervous tissue (glial cells).
5. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?
- A. Gravitational force
- B. Normal force from the ground
- C. Air resistance
- D. The force of throwing
Correct answer: C
Rationale: Gravitational force acts downwards, normal force is perpendicular to motion at the launch point, and the throwing force is gone after release. Only air resistance acts continuously to oppose horizontal motion.
6. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty
- A. Formal
- B. Informal
- C. Staff
- D. Line
Correct answer: B
Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.
