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. Mutations lead to genetic variation in organisms that reproduce asexually.

C. Genetic changes are always harmful to organisms that reproduce asexually.

D. Organisms undergo mutations to become better suited to their environment.

Answer 1

I am going for B. because the ultraviolet light could cause mutation to occur. This is a type of mutagen called mutagen in the environment (its also called a UV light)

A mutation is a change in the nucleotide sequence that can create a new function in the organism and in this case the mutaion may have caused the color to seperate from the light. Hope this helps:)

Answer 2

Answer:

For PLATO itś a   ´´ Mutations lead to genetic variation in organisms that reproduce asexually. ´´
