What is one way that an antibiotic-resistant strain of bacteria can arise?

Answer 1

I'll state two ways.

One way is overusing antibiotics; another is not finishing the course of antibiotics you are prescribed, as this helps individuals with resistant strains to become a resistant strain population.

One way that an antibiotic-resistant strain of bacteria can arise is through the process of natural selection. When bacteria are exposed to antibiotics, those with genetic mutations that confer resistance to the antibiotic have a survival advantage. These resistant bacteria are then able to survive and reproduce, passing on their resistance genes to future generations. Over time, this can lead to the emergence of antibiotic-resistant strains of bacteria.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
