What is the function of ground water?

  1. underground water that is held in the soil and in pervious rocks

  2. a segment of DNA that is involved in producing a polypeptide chain

  3. a monosaccharide sugar that has several forms

  4. a muscular sac attached to the liver that secretes bile and stores it until needed for digestion

The correct answer is: underground water that is held in the soil and in pervious rocks

Ground water plays a crucial role in the Earth's hydrological cycle and is indeed defined as underground water that is held in the soil and in pervious rocks. This water is essential as it recharges aquifers, supports plant growth, and provides water for drinking and irrigation. Ground water is a significant component of our freshwater resources, influencing both ecosystems and human activities. The other options provided address entirely different subjects: the second option relates to genetics and the role of DNA in polypeptide synthesis, the third option refers to carbohydrate chemistry, specifically monosaccharides, and the fourth option pertains to the digestive system and the function of the gallbladder. Each of these options is unrelated to the concept of ground water.
