Final answer:
Viruses are not used to clean up oil spills, but they are used in creating transgenic organisms, developing genetic diversity in flowers, and gene therapy.
Step-by-step explanation:
Out of the given options, cleaning up oil spills is not a beneficial way that viruses are used. Viruses are not typically used for cleaning up oil spills.
On the other hand, viruses are used in several other beneficial ways:
- Creating transgenic organisms: This involves incorporating genes from one species into another to produce desirable traits.
- Developing genetic diversity in flowers: Seeds can be treated with chemical mutagens or radiation to introduce favorable features and increase genetic diversity.
- Gene therapy: This technique involves transferring normal genes to human cells to treat or cure inheritable diseases.
