Answer:
Natural selection
Explanation:
Natural selection is a process where some organisms are able to reproduce more and survive better due to the presence of beneficial genetic traits in them. The other organisms of the same population that lack these traits are not able to survive and reproduce in the same way. The bacterial having drug resistance are able to survive in the presence of drugs in the surroundings. These bacteria will reproduce more and leave more progeny. Over the generations, the proportion of the bacteria with drug resistance will increase. This represents an example of natural selection.

For the answer to the question above, <span>If animals are related they share genes in common. The more genes they share on their DNA, the more alike they may be, like the rodents.
However, the behavior is caused not only by genes but by the environment plays an important part as well.</span>
Identify the biotic and abiotic factors that make up a real ecosystem. Observe the relationships between organisms and their environment. Understand that each part of the ecosystem performs an important function important for maintaining balance in such ecosystem!
