Answer:
Antibiotic X could be used to identify mitochondria in living cells.
Step-by-step explanation:
As you already know, antibiotics are products that can interfere with the bacterial growth or cause the death of these beings. However, as shown in the question above, one researcher eventually discovered another utility for antibiotic X. The researcher noted that when placed on a dish containing a cell culture, antibiotic x was highly concentrated in the mitochondria of these cells. This means that in addition to performing the previously known function, this antibiotic could be used to identify mitochondria in living cells.
