Why do Streptomycetes have ability to produce so many specialised molecules?

Various streptomycete soil bacteria have ability to produce a range of molecules called secondary metabolites.

See if you can relate a specialised molecule, or streptomycete general metabolic versatility, to one of the following aspects of streptomycete biology.

1. Habitat
2. Life-cycle
3. Cell fusion between different vegetative hyphae
4. Presence of conjugative plasmids
5. Nutrition and nutrient capture
   
6. Chromosomal structure
7. QS
8. Membrane physiology
9. Stress - UV exposure, dehydration
10. Aerial hyphae
11. Spore survival

Good luck.
