Question

A scientist shines ultraviolet light on a colony of blue colored bacteria. She then places colonies of the bacteria in separate Petri dishes. After allowing the bacteria to replicate for several generations, the scientist observes that some of the dishes now contain colonies with purple and red colored bacteria. What can be concluded from this observation?

A.
Asexual organisms will undergo genetic changes if placed in a Petri dish.
B.
Organisms undergo mutations to become better suited to their environment.
C.
Mutations lead to genetic variation in organisms that reproduce asexually.
D.
Genetic changes are always harmful to organisms that reproduce asexually.

Answer 1

The correct answer is option B.

Step-by-step explanation:

The ultraviolet light leads to a mutation in bacteria. It is a probability that UV light had an impact on a colony of blue-colored bacteria resulting in a mutation. The mutagen found in the ultraviolet light leads to a mutation in bacteria. It is known that mutation refers to a change in the genetic substance and can lead to more functionalities in a species.
