Answer:
Most often, food is contaminated by infected food handlers. Food may also be contaminated if it is grown in or irrigated with water contaminated with norovirus, as has been shown with oysters, lettuce, and raspberries.
Explanation:
Answer: The FIRE SIZE should be taken into consideration when using a fire extinguisher.
Explanation:
Firefighting is defined as the steps followed to put off and prevent spread of unwanted fire. The particular technique and equipment that is used to put out fire will largely depend on the root cause of the fire and location of the fire itself.The fire may be caused by electricity or flammable liquids/ chemicals. There are different equipments that can be used to put out fire, these include:
--> Fire blanket: to extinguish fire on personal clothing or a small fire on the floor or bench.
--> Buckets of sand or dry soil (kept free of refuse): this is used to extinguish a free flowing liquid fire.
--> Buckets of water: to extinguish paper, fabric and wood fires. Water, however, must never be used to extinguish an electrical fire or one caused by a flammable chemical.
--> Dry powder chemical FIRE EXTINGUISHER: to extinguish electrical fires and fires caused by flammable liquids.
Generally FIRE EXTINGUISHER is an equipment used in emergency situations to put out SMALL fire to avoid it's spread. Prior to fighting any fire with a portable fire extinguisher, you must take into consideration the FIRE SIZE as not all fire can be extinguished using a portable fire extinguisher.
Many people put out SMALL FIRE quite safely using a portable fire extinguisher. However, death or serious injury can occur by tackling a fire which is beyond your capabilities. Only tackle a fire in its very early stages and always ensure you put your own and other peoples safety first.
The next step that should be taken by the nurse is the intravenous administration of Dopamine.
<h3>What is Dopamine?</h3>
The drug dopamine is a chemical that naturally exists in the body. It functions by strengthening the heart's pumping action and enhancing blood flow to the kidneys. When you are in shock, certain conditions can be treated with dopamine injection (Intropin).
Dopamine is indicated in following conditions:
- Poor cardiac output (when the heart doesn’t pump out enough blood)
- Poor blood flow to vital organs
- Some cases of septic shock
Dopamine contributes to how we experience pleasure. It plays a significant role in the exceptional ability of humans to think and plan. It encourages us to work hard, concentrate, and find things interesting.
Your body distributes it throughout the brain's four main circuits. You don't detect it (or perhaps even know about it), like with most other systems in the body, until there is a problem.

Taking into account the definition of molarity, the molar concentration of the table salt is 1.368 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Molar concentration of the table salt</h3>
In this case, you have:
- number of moles= 10 g×
= 0.171 moles [being 
the molar mass of NaCl] - volume= 125 mL= 0.125 L [being 1000 mL= 1 L]
Replacing in the definition of molarity:
Solving:
<u><em>molarity= 1.368 </em></u>
Finally, the molar concentration of the table salt is 1.368 .
