Two mechanisms that affect the genetic diveristy of bacterial population
Horizontal gene transfer involves several mechanisms that can increase the genetic diversity of bacterial populations.
One of these mechanisms is bacterial conjugation in which a donor cell transfers genetic material to a recipient cell through a pili which function as a conduit.
Another mechanism of variability is through bacteriophages where genetic material is moved from one bacterium to another, this method is called transduction.
succession returns a disturbed
ecosystem to a more stable state. this is also classified into two (2) types:
primary succession and secondary succession. the primary succession arises when
a new land is transformed and a bare rock has been exposed providing an environment
that can be occupied for the first time. while, secondary succession occurs
when a previously occupied environment was disturbed that kills much of all its
