Answer: i think is chemical is correct answer
I would say the stomach is most similar to the mitochondria. This is because the purpose of the mitochondria in a cell is to break down molecules, such as glucose, nucleic & fatty acids, etc., into ATP (cell energy) so it can be used productively. The purpose of the stomach is to break down molecules of whatever is being consumed, so it can later be absorbed by the large and small intestine, and what is absorbed goes into the cells to be used productively.
Put simply, the stomach is similar to the mitochondria because they both provide energy for the greater thing they function, cell or body.
Hope this helps, and hope I was the brainliest! :)
