Question

Resistant bacteria are more likely to survive a dose of antibiotics, and are therefore more likely to reproduce. The resistance allele will be more common in the next generation.

Answer 1

The question discusses the topic of antibiotic-resistant bacteria. These are bacteria that have developed a resistance to certain antibiotics due to a mutation in their genetic material. As a result of natural selection, these resistant bacteria survive antibiotic treatment and multiply, making them more common in subsequent generations.

Step-by-step explanation:

The subject of this question is Biology, specifically evolution and adaptation in bacteria. Resistant bacteria are those that have developed a mutation making them capable of surviving exposure to specific antibiotics. When these antibiotics are used, they kill non-resistant bacteria, but the resistant bacteria survive and multiply, increasing their presence in the bacterial population. This is an example of natural selection because the trait that provides resistance (the resistance allele) gives these bacteria a survival advantage, leading to an increase in its frequency in the next generation. This phenomenon is a significant concern in medicine, as it makes treating bacterial infections more difficult.
