Answer 2

Answer:

Some bacteria are able to grow in streptomycin containing medium due to “Natural Selection”.

Explanation:

• Charles Darwin put forth the term “Natural Selection” in the living population by Nature. Variation is always present in the population and the chances of mutation are less than 1% in a given population then also it does occur.
• It is a major process for evolution within a population.  A particular variation might exist phenotypically, but mutation or with any reason when this trait gets a reproductive advantage this creates Speciation in the population.
