Ответ:
The correct option is: A. nitrogen fixation
Explanation:
Nitrogen cycle is the circulation of nitrogen through the living and non-living components of the biosphere.
Nitrogen fixation is the first step of the nitrogen cycle. It involves the conversion of free atmospheric nitrogen in the atmosphere into biologically usable ammonia in the soil, by the nitrogenase enzyme. This enzyme is produced by nitrogen-fixing bacteria present in the soil.
Ответ:
B. Add more water to decrease the concentration.
Explanation:
If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.
Concentration is the amount of solute in a solution. Conductivity deals with the ability of a solution to allow the passage of current.Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.
Adding more water increases the amount of solvent and the concentration reduces.
