Well with the ph above 7 that means the water is more of a base due to the salt within the water. the decrease in the ph is due to gloabal warming and the melting of ice which is somewhat diluting the water more. the wildlife within the ocean has been there since you or i so some creatures have developed a very specific habbitat and less salt withing the water could have effects on them. one such instace is if the organism needs a lot of salt. a decrease in salt would mean that their cells would bloat with water until they explode. this would obviously hurt the species as a whole and in turn effect the whole food chain.
Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. <span>
