Most prokaryotes, I think, have the best ability to live in extreme conditions. If you take this into consideration, what kind of organisms are most likely to be prokaryotes—more specifically, extremophiles?
Antibiotics added to livestock feed have been found to increase their growth rate, reduce incidence of infection, reduces mortality and improve feed conversion ratio or feed efficiency.
The cell cycle is the replication of reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in many different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called binary fission, allows for them to live on by dividing into two new daughter cells.

Learned behavior or learned trait. It’s something they develop, not something they already have.
