Chemistry

1. What is the product of the complete combustion of propane (C3H8)?

Correct answer: a

Rationale: Complete combustion of hydrocarbons produces carbon dioxide (CO2) and water.

2. Which structure in the respiratory system is responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream?

Correct answer: C

Rationale: The correct answer is C, Alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from the air we breathe diffuses into the bloodstream through the alveoli walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. The trachea and bronchi are responsible for carrying air to and from the lungs, while bronchioles are small air passages within the lungs that branch off from the bronchi. However, the actual gas exchange occurs in the alveoli, making them crucial for the respiratory system's function.

3. What is the principle behind optical fibers used in communication?

Correct answer: C

Rationale: Optical fibers used in communication rely on the principle of total internal reflection guiding light through the fiber core. When light enters the fiber at a certain angle, it reflects off the boundary between the core and cladding, ensuring that the light remains trapped within the core and travels along the fiber without significant loss of signal. This total internal reflection allows for efficient transmission of light signals over long distances in optical communication systems.

4. Which type of wave requires a medium to travel through?

Correct answer: d

Rationale: Both mechanical waves (such as sound waves) and electromagnetic waves (like light) have different requirements for propagation, but both can travel through a medium.

5. Which part of the brain controls balance and coordination?

Correct answer: A

Rationale: Rationale: The cerebellum is the part of the brain responsible for coordinating voluntary movements, balance, and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate motor movements. The hypothalamus is involved in regulating various bodily functions such as temperature, hunger, and thirst. The occipital lobe is primarily responsible for processing visual information. The corpus callosum is a structure that connects the two hemispheres of the brain and facilitates communication between them.

6. What is the main point of the passage?

Correct answer: C

Rationale: The passage clearly identifies human activities as the cause of climate change and emphasizes the need for global action, aligning with C.
