Step-by-step explanation:
The most likely result of removing an organ from an animal and keeping it alive in a laboratory is that the organ will remain alive and functional. While the organ may no longer be supported by the animal's body, it can still receive nutrients and oxygen in the laboratory setting, allowing it to continue functioning. Examples of this include keeping a heart beating outside of the body or maintaining kidney function in a laboratory setting.
