1. Which of the following properties is characteristic of water?

Correct answer: D

Rationale: The correct answer is D because water's polarity enables it to dissolve a wide variety of substances, making it a versatile solvent. This property is due to water's ability to form hydrogen bonds with other molecules, allowing it to break them apart and surround the solute particles, facilitating dissolution. Choices A, B, and C are incorrect as water having a neutral pH, a high specific heat capacity, and polar covalent bonds are also true properties of water. However, the most relevant property related to its versatility as a solvent is its dissolving capability.

2. Which mineral is essential for muscle function and nerve transmission?

Correct answer: D

Rationale: Potassium is the correct answer as it is essential for muscle function and nerve transmission. Potassium plays a crucial role in regulating muscle contractions, including the heart's beating, and is vital for transmitting electrical signals within the nervous system. Calcium (Choice A) is important for muscle contraction but is not the primary mineral for nerve transmission. Iron (Choice B) is important for oxygen transport in the blood. Sodium (Choice C) is important for fluid balance but is not primarily responsible for muscle function and nerve transmission.

3. Which lobe of the brain is primarily responsible for processing visual information?

Correct answer: D

Rationale: The occipital lobe, located at the back of the brain, is primarily responsible for processing visual information. It contains the primary visual cortex, which interprets visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, the parietal lobe in sensory processing and spatial awareness, and the temporal lobe in auditory processing and memory. Therefore, choices A, B, and C are incorrect as they are associated with functions different from visual processing.

4. What is a benefit of a taxonomic system?

Correct answer: D

Rationale: The correct answer is D. A taxonomic system allows scientists to classify living organisms based on their molecular and genetic traits. This classification helps in understanding the relationships and evolutionary history of different organisms, providing insights into their characteristics and behaviors. Choices A, B, and C do not directly relate to the primary purpose and benefit of a taxonomic system, which is the systematic classification of organisms.

5. What is the role of the large intestine in the digestive system?

Correct answer: B

Rationale: The correct answer is B. The large intestine plays a crucial role in absorbing water from indigestible food matter and forming feces for elimination. Choice A is incorrect because the breakdown of proteins primarily occurs in the stomach and small intestine. Choice C is incorrect as the digestion of fats primarily occurs in the small intestine. Choice D is incorrect as neutralizing stomach acid is mainly the function of the stomach lining and not the large intestine.
