Answer:
<u>A. Antibiotic Y</u>
Explanation:
Kirby-Bauer assay is used to determine the susceptibility of an organism to the given antibiotics. It determines susceptibility by the diameter of zone of inhibition around antibiotic disks. Since the zone of inhibition of Antibiotic Y is greater than the Antibiotic X so Antibiotic is better or more powerful in killing this particular microorganism.
Because gas particles are very far from each other so the amount of space between them can easily change therefore doesn’t have a fixed shape and since the particles are always in motion and try to fill there container gas doesn’t have a fixed volume either

The contamination cleanup strategy called bioremediation—using naturally occurring or genetically modified microbes to clean up our messes—is gaining steam, as scientists devise new ways to use bugs against mercury, oil spills, radioactive waste and more.
