The answer is <span>-Only the few bacteria that were immune to the antibiotic survived and reproduced, making all their offspring immune to it as well.
Bacteria (or any other organism) are not able to make changes to their DNA in order to protect themselves or to learn to remove the receptors on their cell surfaces. If they were able to produce toxins against the antibiotics, they would all survive.
These leave the second choice as the correct answer. This is the real situation, and is a good example of natural selection.</span>

The scientists can predict that the finches on the island are mostly insectivores.
This is a generalization because the scientist have taken 12 finches as a sample population and predicted the food habits of the Entire population of finches living on the island.
Explanation:
- Generalization refers to deriving a conclusion about anything by observing any sample of it.
- Usually generalizations are done while studying large populations.
- We can define generalization as an act in which broad inferences are drawn by small observation.
- It makes the qualitative evaluation easy when it is very difficult to study each an every individual of population.
- In this experiment the scientists have observed only 12 out of many finches living on the island.
- They observed only these 12 finches and inferred about the eating habits of all the finches in the island.
- So, here a small observation of only 12 finches was used to give a broader inference about all the finches. Thus, it is a generalization.
