Answer:

The correct answer is C. Kirby-Bauer test

Explanation:

Kirby-Bauer test is used to check the sensitivity of a particular bacteria towards an antimicrobial drug. So in this test, a pure culture of bacteria is isolated and its lawn is prepared on a suitable agar medium with the presence of discs of antibiotics that have known antibiotic amount.

Then the agar plate is incubated for appropriate time so that the bacteria can grow in the agar plate. After incubation, if the microbe is susceptible to antibiotic then a zone of inhibition will be seen where antibiotic growth is absent. More the zone of inhibition more will be the susceptibility of the bacteria towards that antibiotic.  

So this test involves measuring and evaluating the zone of inhibition around antibiotic disc therefore the correct answer is C.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
djverab [1.8K]

Answer:

<u>C</u>

Explanation:

✨ plant-like algae bloom in polluted waters and create oxygen-depleted dead zones.✨

✨Water pollution that alters a plant’s surrounding pH level, such as acid rain, can harm or kill the plant. Acid rain forms because of atmospheric sulfur dioxide and nitrogen dioxide, which are emitted from natural and human-made sources. These include volcanic activity and burning fossil fuels.✨
