Ascientist 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.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
