Question

mrsa (methicillin - resistant staphylococcus aureus) is a type of bacteria that has developed resistance to many antibiotics, making it difficult to treat. mrsa infections can occur in wounds, the bloodstream, or the lungs. because it is resistant to common medicines, doctors must use stronger or less common antibiotics to fight it.
the human body works to maintain homeostasis, or stable internal conditions, when infected with mrsa. for example, the immune system increases white blood cell activity to attack the bacteria, and the body may raise its temperature (fever) to slow bacterial growth. if the infection spreads too much, however, it can disrupt homeostasis by causing dangerous changes in blood pressure, temperature, and organ function.
mrsa shows how both bacteria and humans adapt: bacteria evolve resistance to survive, while the human body responds with defense mechanisms to maintain balance.
why is mrsa difficult to treat?
it grows very slowly.
it resists many antibiotics.
it does not cause infection.
it produces oxygen.

Explanation:

The text explicitly states “MRSA (Methicillin - Resistant Staphylococcus aureus) is a type of bacteria that has developed resistance to many antibiotics, making it difficult to treat.” This directly links MRSA's difficulty in treatment to its resistance against multiple antibiotics.

Answer:

It resists many antibiotics.
