Why are vestigial structures are considered examples of homologous structures?

Vera_Pavlovna [14]

Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered the evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time.

An acidic solution of pH 5 has TIMES as many hydrogen ions (H+) as does a solution of pH 6.

Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

The concentration of hydrogen ions is inversely related to its pH
More hydrogen ions present, the lower the pH
The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,

=> 5 = -log (H+)

=> H+ = $10^{-5}$ (for pH = 5)

=> pH = -log(H+)

=> 6 = -log (H+)

=> H+ = $10^{-6}$ (for pH = 6)

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
