Does anyone know the definition of an OPPORTUNISTIC POPULATION? I have looked all over the internet and i cant find anything.

Opportunistic species are those that colonise an unstable or periodically extreme environment.They can colonise quickly, although they are often‘out competed’ by other organisms once the environment becomes stable. They are prevalent where man or nature has created a disturbance where the stable species have been killed or moved. This could be a landslie, fire, flood, logging, mining etc. An OPPORTUNISTIC POPULATION is just a given number of such a species living within the disturbed area.

can someone please help me with these questions?:
1. Some prokaryotes are capable of reproducing once every half-hour.
Suppose you placed a single bacterium in a suitable culture medium and it (and its descendants) proceeded to reproduce at this rate. How many cells would be present after 2 hours? After 12 hours? What factors determine how long this kind of increase can continue?

2. Why can prokaryotes quickly reinfect a patient if they were not wiped out? How might this result in evolution of drug resistant pathogens?
