55 is the answer
!!!!!!!!!!!!!!!!!!!!!!!!!!
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.
Answer:
<h2>Coevolution</h2>
Explanation:
Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.
In coevolution , two or more species reciprocally affect evolution of each other by natural selection.
Coevolution Examples:
There are lots of examples of coevolution, some are here
i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.
ii) coevolution of Herbivores and plants,
iii) coevolution of Acacia ants and Acacias and
iii) coevolution of Flowering Plants and Pollinators and many others.

Answer:
Carbon Dioxide / Gas
Explanation:
When carbon is in the atmosphere it is usually in the form of molecules of carbon dioxide that is released by living organisms such as humans, plants, animals etc and it is a gas.
I hope this answer helps.
