They are not individual organisms.
That is apiculture
Apiculture or beekeeping.
Mitochondria is the only possible way in clinical studies.
Considering that most eukaryotic cells have mitochondria and that dinosaurs are eukaryotes like all other animals that ever lived, it is certain that they did have mitochondria in their cells. In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
BY ripping it apart
tissue culturing
The past participle form of "culture" is "cultured," and the present participle form is "culturing."
Mitochondria are organelles. They are much smaller than the cell they are in. Several mitochondria can easily fit in a cell without affecting the other organelles. In fact, they make life possible. Not because they produce ATP, but because they reside in the cells and communicate with the force.
Some cells only grow in culture.
Bacteremia is diagnosed by culturing the blood for bacteria
The requirements in culturing bacteria is the right temperature, gas, pH and moisture to assure proper growth of bacteria.
culturing cells to find out which took the gene of interest.
