Reading

1. The main idea of the passage is that

Correct answer: B

Rationale: Choice B accurately captures the passage's emphasis on history's multifaceted impact, providing insights into the present and potential visions for the future.

2. What is the process of converting light energy into chemical energy called?

Correct answer: C

Rationale: Rationale: - Respiration (Option A) is the process by which cells break down glucose to release energy. - Fermentation (Option B) is an anaerobic process that also involves the breakdown of glucose to release energy. - Hydrolysis (Option D) is a chemical process that involves the breakdown of molecules by adding water. Photosynthesis (Option C) is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is essential for the survival of plants and ultimately sustains life on Earth by providing oxygen for other organisms to breathe and serving as a source of energy in the food chain.

3. Which structure, located between the pons and the spinal cord, plays a crucial role in coordinating movements, maintaining balance, and posture?

Correct answer: c

Rationale: The correct answer is C: Cerebellum. The cerebellum is the structure located between the pons and the spinal cord that plays a crucial role in coordinating movements, maintaining balance, and posture. It receives information from sensory systems and integrates this input to fine-tune motor activity. The thalamus (A) is a relay station for sensory information, the medulla oblongata (B) is involved in vital functions like heartbeat and breathing, and the hypothalamus (D) regulates various metabolic processes and homeostasis. Therefore, the cerebellum is the most appropriate choice for a structure responsible for movement coordination and balance.

4. Which term describes the functional unit of a skeletal muscle responsible for muscle contraction?

Correct answer: b

Rationale: The correct answer is B: Sarcomere. A sarcomere is the functional unit of a skeletal muscle responsible for muscle contraction. It is made up of overlapping filaments of actin and myosin proteins. Myofibrils are long, cylindrical structures within muscle cells that contain sarcomeres. Tendons are tough bands of fibrous connective tissue that connect muscles to bones and facilitate movement. Myoglobin is a protein found in muscle cells that stores oxygen for muscle use during exercise. Therefore, the sarcomere is specifically responsible for muscle contraction, making it the correct answer in this question.

5. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

Correct answer: C

Rationale: Work is defined as force multiplied by distance, and as long as the force remains constant, the work done increases proportionally to the distance moved, even if the box slows down due to friction.

6. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table.
