Answer:
The first thing you need to know here is Darwin's theory, once you understand how the adaptation in evolution works, you can even know the right graphic to the growth of this beetles' population
Step-by-step explanation:
Darwin's theory works basically in the way that when a population cannot survive environment's conditions, natural or not, this population will either die, or adapt itself through mutations on its genes. In the case of these beetles, what happens is that the pesticide will kill most of the beetles, until one of them develops a gene with the right protection to this pesticide, and once this happens, the population will start growing normally again. It works in the same way for antibiotics and bacteria.
