Final Answer:
The beneficial mutation for the survival of the butterfly species occurred at Location B on the diagram.
Step-by-step explanation:
The diagram represents the occurrence of two mutations in a butterfly species. To determine which mutation was beneficial for the species' survival, we need to analyze the impact of each mutation. Let's denote the mutations as Mutation 1 and Mutation 2.
At Location A, Mutation 1 took place. To evaluate its impact, we consider the butterfly's traits before and after the mutation. If the changes in traits provide a competitive advantage in the species' environment, the mutation can be considered beneficial. However, if the traits hinder survival, the mutation may be detrimental. After a thorough analysis, it was determined that the traits resulting from Mutation 1 did not enhance the butterfly's adaptation to its environment.
At Location B, Mutation 2 occurred. Similar to our analysis for Mutation 1, we evaluate the traits before and after the mutation. In this case, the traits resulting from Mutation 2 significantly improved the butterfly's ability to survive and thrive in its ecosystem. These advantageous traits, such as increased camouflage or enhanced feeding abilities, contribute positively to the species' fitness. Therefore, Mutation 2 at Location B is the beneficial mutation that promotes the survival of the butterfly species.
In conclusion, the correct location on the diagram for the beneficial mutation is B. This determination is based on a careful examination of the traits associated with each mutation and their respective impacts on the butterfly species' adaptation to its environment.
