  Sore throat and nausea
- B.

Explanation
Food poisoning is caused by consuming contaminated food or water, leading to the growth of bacteria, viruses, or parasites in the digestive system. Vomiting and diarrhea are common symptoms of food poisoning as the body tries to expel the harmful substances. These symptoms occur due to the body's natural defense mechanism to get rid of the toxins. Other symptoms like sore throat, headache, and itching may also be present in some cases, but vomiting and diarrhea are the most typical indicators of food poisoning.

Explanation

Symptoms such as diarrhea, nausea, vomiting, and stomach cramps may occur during this time. It is important to note that the duration of the illness can vary depending on the specific bacteria involved, the individual's immune system, and other factors.

Correct Answer
C. Food moisture, warmth and time

Explanation
Bacteria need food, moisture, warmth, and time in order to multiply. Food provides the necessary nutrients for bacteria to grow and reproduce. Moisture is important for the metabolic processes of bacteria. Warmth helps to facilitate the enzymatic reactions required for bacterial growth. Time allows for the bacteria to undergo cell division and multiply. Therefore, all these factors are essential for bacterial multiplication.

- A.
  
  20 minutes
- B.
  
  2 days
- C.
  
  14 days
- D.
  
  28 days
Correct Answer
B. 2 days

Explanation
Food-borne illnesses caused by bacteria typically last for a duration of 2 days. This is because bacteria can multiply rapidly in food, leading to the production of toxins that can cause illness when consumed. The symptoms of food poisoning, such as nausea, vomiting, diarrhea, and abdominal pain, usually appear within a few hours to a few days after consuming contaminated food. In most cases, these symptoms resolve within a couple of days as the body's immune system fights off the bacteria and eliminates the toxins. However, the duration of illness can vary depending on the specific bacteria involved and the individual's immune response.
