What does the biodiversity on Earth indicate about its organisms?
mixas84 [53]

A high biodiversity tally may indicate that some of its organisms may be able to survive drastic environmental changes. If there weren't at least a few organisms that contribute to biodiversity, most of the biotic Earth would be gone by now.

For example, woolly mammoths were unable to adapt to the up-and-coming warmth of the poles. Because they lacked biodiversity among their species, all of them died out and weren't able to adapt to the heat.

I hope I helped!

The hydrogen ion concentration of a solution is indicated by its<br> ___ value.
rosijanka [135]

The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.

Explanation:

  • A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
  • Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
  • The pH is then equal to minus the logarithm of the concentration value.
  • Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
  • The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
  • Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.
