Final answer:
Multiple nuclei may arise in biology through nuclear fission and genome fusion by endosymbiosis.
Step-by-step explanation:
The concept of multiple nuclei can apply to different areas in biology, so I will provide two possibilities:
- In the context of nuclear fission, multiple nuclei may arise when heavier nucleoids split into two smaller, more stable nucleoids. This process releases a large amount of energy.
- In the context of eukaryotic cells, multiple nuclei may arise through genome fusion by endosymbiosis, where archaeal and bacterial species combine to form cells with two lipid bilayer membranes.
