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.
Bachiko congratulated her staff when the team received an industry award for their project, and also sent a companywide e-mail announcing it. here, Bachiko is using her <u>personalized</u> power.
In the example above, Bachiko is using his power. Personalized power is the power in which a person has a superiority complex and thinks that he is superior to others. Also, he made sure that people knew that he was someone else's boss.
The sources of management power are as follows:
Positional power
- strength because of the award/prize.
- power because you have a certain authority.
- power because of the punishment given.
Personal power
- power because you have certain knowledge and abilities.
- power because of your attractive personality.

The plasma membrane of the enveloped alga cell serves as the source of the apicoplast's second outermost membrane.
<h3>Where did all chloroplasts come from?</h3>
Chloroplasts were first established in eukaryotes through an endosymbiotic relationship with a cyanobacterium; they later spread through the evolution of eukaryotic hosts and the subsequent engulfment of eukaryotic algae by formerly nonphotosynthetic eukaryotes.
<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>
Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.
