Aspecies of plants that adapts to become more tolerant of toxic heavy metals produced as a result of human mining activities is an example of

a. stabilizing selection

b. disruptive selection

c. directional selection

d. mutation

C

Explanation:

This kind of selection favours the individuals on one end of an extreme trait in a population. In this case the extreme trait is a high tolerance for heavy metals. The individuals on this extreme end, therefore, survive more than the rest of the population and are able to pass their genes to the subsequent generations.With every generation, there are more and more individuals that  are tolerant of heavy metals leading to an evolution of the species towards tolerance to heavy metals.

substitution is the answer in this case

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

community
