Caravan is just a parade in a different font
Prokaryotes are usually smaller than eukaryotes. They also don’t have a nucleus so DNA is in the cytoplasm. They also have no organelle membranes where as eukaryotes do. Domains of prokaryotes include Bacteria and Archaea, and all eukaryotes are in the domain Eukarya. Both can be free living, but only eukaryotes can be multicellular. Prokaryotes first appeared on earth about 3.5 billions then eukaryotes appeared about a billion years later. Etc....
You could extrapolate from this article that if you eliminated mutations in mitochondria, you could eliminate disease.
Answer: Option C
<u>Explanation:</u>
Mitochondria are found all over our body except in red blood cells. This mitochondria aids in the process of ATP synthesis. Sometimes mutation occurs in the mitochondrial DNA which causes disease in the mitochondria and hence is the root cause of various diseases.
In most cells the mutated mitochondria are removed by the mitophagy which is a natural phenomenon found in all the cells. The mtDNA mutations caused are actually inherited from the mother. Now scientists have developed ways to eliminate the mutated mitochondria from the mother either before or after fertilization. Hence by altering the mutated mitochondria we can eliminate various diseases.
Protein act as buffers. Buffers are resistant to pH changes. So when too much acidic components are present in the blood, proteins bind to them so that it does not change the net pH of the blood. Example of this is the hemoglobin or the red blood cells.
