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.

Ian and Joanne have been married for ten years and have two children. Recently, a number of family-related problems have occurre

deff fn [24]

Answer: Stressor overload

Explanation: When two have been married for ten years as Ian and Joanne, then there are many problems that have not been resolved, not all, but there are many unresolved, and new ones always appear. All these problems arise from the large number of requests made each new day and require the reaction of the married couple in response. When these reactions are perceived as problems, sometimes for real reasons, sometimes for unrealistic ones, then these demanding reactions are experienced as problems, which become larger and cause new problems. The moment when the number of these problems becomes too large, it causes a certain breaking point in the physiological and psychological aspect of human beings, which is stressor overload. Then people become vulnerable to each and every problem due to the accumulated stress, and often cannot cope with problems that were once easily resolved.
