Tatiana [17]

Answer:

2. Bacteria that have a zone of inhibition are considered susceptible to the tested drug.

3. Bacteria that lack a zone of inhibition are resistant to the tested drug.

4. This test determines if a bacterium is resistant to a specific antibacterial drug.

Explanation:

The Kirby-Bauer test is a technique used in laboratories to assess the sensitivity of bacteria to antibiotics. This is one of the most reliable sensitivity tests in the world and is used in several areas such as health, agriculture, zoology, among others.

The test is done by applying antibiotic discs to a petri dish containing culture medium and a growing bacterium. When the bacterium grows inside the plate, it is observed whether the antibiotic discs were able to cause zones of inhibition of this growth.

Bacteria that do not have zones of inhibition are considered resistant to antibiotics, whereas bacteria that have zones of inhibition are considered susceptible.

We can conclude that one of the main differences between a society based on caste versus one based on class is that:______.
olga_2 [115]

We might draw the conclusion that one of the key distinctions between societies based on caste and those based on class is the prevalence of social mobility in the latter.

<h3>What is caste based society?</h3>
  • Endogamy, the hereditary transfer of a way of life that frequently includes a profession, ritual rank in a hierarchy, customary social contact,
  • And exclusion based on cultural conceptions of purity and contamination are all characteristics of caste, a type of social stratification.
  • Due to the system, the top castes now have privileges over the lower castes, which were frequently suppressed by those in positions of power.
  • Inter-caste unions were outlawed for many years, and in villages, castes primarily lived apart and did not share facilities like wells.
  • However, there have historically been a variety of caste systems around the world, with Africa and Asia being the most noteworthy examples.
  • The caste systems of the Moors, Tuaregs, Somalis, Indians, Songbuns, and Koreans are a few examples.
