In artificial selection, breeders select parent organisms with desired characteristics, in the hopes that when they are crossed, the desired variations will appear in the offspring. ... If the organism is "fit" it does survive and reproduce, thus possibly passing its traits to future generations.
The correct answer is option A, that is, a solution with a pH of 1.
pH refers to the unit of measure utilized to articulate the extent of acidity of a substance. The pH scale varies from 0 to 14. A pH of 0 means a very high acid activity, the hydrochloric acid, and nitric acid are very strong with pH values of 0, while the stomach acid exhibits a pH of 1.
Technically, the scale of pH, in reality, depicts the amount of positively charged H+ ions and negatively charged OH- ions in a solution. The pH scale is a logarithmic one, that is, each unit of pH exhibits 10 times as more ions of hydrogens in comparison to the unit above it.
Therefore, in a solution of pH 1, there are 10^9 times more hydrogen ions in comparison to the solution at pH 10.
