Name 2 reasons why bacteria are resistant to antibiotics?

Answer:

Antibiotic resistance is accelerated when the presence of antibiotics pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antibiotic-resistant germs survive and multiply.

Read the scenario.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.

The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.

Which question most closely relates to the biologist's observations and collected data?

Are the golden frogs succumbing to a fungal infection?

Did the golden frogs migrate to a new habitat?

Why was a copper mine built so close to the stream?

Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?
