<span>The function of the nephron is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine</span>
Sounds quite appealing as the molecules listed are relatively common. However, they are only reactive under precise environmental conditions, including energy, which are far from adequate to produce the progressively higher levels of complexity required for the levels of biochemical assembly needed for life.
The next higher levels also require sulfur and phosphorus for the formation of homochiral amino acids and sugars, which are elemental level molecules required for DNA construction, which is found in all living things. These ostensibly are the "organic molecules" but only function as homochiral versions.
The mixture is solids, liquids and gases, which makes a name of mythical primordial or prebiotic soup most likely.

Answer:
The correct option is A) sustainable use
Explanation:
Sustainable use of resources can be explained as using resources in such a way that they can be consumed by people today and even the next generations. If the usage of resources is not managed, then soon Earth will become depleted of useful resources and life on Earth will not be possible. One such threat is the usage of water. Many of the areas of Earth are already depleted of water. Hence, water management should be made sustainable.
In meiosis chromsomes come together and share genetic information between daughter cells in prophase one, where in mitosis instead of the ending sequence being four cell two of the cells are the same.
