Answer:
The correct option is : a. diameter
Explanation:
The Kirby–Bauer test or the disk diffusion test, is a method to determine the antibiotic sensitivity of the given bacteria. This test involves the use of antibiotic discs to determine the effect of antibiotics on the bacteria.
In this test, the wafers having antibiotics and the bacteria are placed on the agar plate and incubated. If the antibiotics present stops the growth of the bacteria, there will be an area around wafer with no bacterial growth, such an area is known as the zone of inhibition.
<u>The </u><u>diameter of this zone of inhibition</u><u> is measured to determine the </u><u>antibiotic sensitivity of the given bacteria</u><u>.</u>
The answer is : b. Theoretically, noise pollution could be so great that it could kill a person. Noise pollution affect our sense of hearing... leading to hearing loss. It also disturb our sleep which could lead to fatigue. Long-term noise above a certain level can have a harmful influence on our health. Research shows that road traffic and aircraft noise increase the risk of high blood pressure. Noise pollution also affects wildlife, where animals depend wholly on their hearing for hunting.
