    What's the other term for regurgitation? - ProProfs

    What's the other term for regurgitation?

    • Reflux

    • Flood

    • Relapse

    • Explosion

    Correct Answer
    A. Reflux
    Explanation
    Regurgitation refers to the backward flow of stomach contents into the esophagus. The term "reflux" is synonymous with regurgitation and is commonly used to describe this condition. Reflux occurs when the lower esophageal sphincter, a muscular ring that separates the stomach from the esophagus, weakens or relaxes, allowing stomach acid and partially digested food to flow back up into the esophagus. Therefore, reflux is the other term for regurgitation.

    What's the other term for potable water? - ProProfs

    What's the other term for potable water?

    • Tap water

    • Bottled water

    • Drinking water

    • Rain water

    Correct Answer
    A. Drinking water
    Explanation
    The other term for potable water is drinking water. Potable water refers to water that is safe and suitable for consumption by humans. It is treated and purified to remove impurities and contaminants, making it suitable for drinking. Tap water, bottled water, and rainwater can all fall under the category of drinking water if they meet the necessary quality standards.

    What represents category 5 into the risk of water contamination? - ProProfs

    What represents category 5 into the risk of water contamination?

    • Boiling water

    • Salty water

    • Serious health risk.

    • Muddy water

    Correct Answer
    A. Serious health risk.
    Explanation
    Category 5 represents a serious health risk in terms of water contamination. This means that the water is highly contaminated and poses a significant threat to human health. It may contain harmful bacteria, viruses, chemicals, or other contaminants that can cause severe illness or even death if consumed. Therefore, it is important to avoid drinking or using this water without proper treatment or filtration.

    What's the other term for fire sprinkler? - ProProfs

    What's the other term for fire sprinkler?

    • Alarm

    • Fire detector

    • Sprinkler head

    • Alert

    Correct Answer
    A. Sprinkler head
    Explanation
    The other term for fire sprinkler is "Sprinkler head." A fire sprinkler system consists of a network of pipes with sprinkler heads attached to them. When a fire is detected, the heat activates the sprinkler head, causing it to release water and suppress the fire. The term "Sprinkler head" refers specifically to the part of the sprinkler system that discharges water.

    What is a back siphonage? - ProProfs

    What is a back siphonage?

    • It's the result of supply pressure being lowered below that of the system.

    • It's the result of pressure being lowered.

    • It's the result of supply pressure being increased above that of the system.

    • It's the result of pressure being lowered below water.

    Correct Answer
    A. It's the result of supply pressure being lowered below that of the system.
    Explanation
    Back siphonage occurs when the supply pressure of a system is reduced below that of the system itself. This can happen when there is a sudden drop in pressure in the supply line, causing a reverse flow of water or other fluids. This can be problematic as it can lead to contamination of the water supply, especially if there are cross-connections between potable and non-potable water sources. To prevent back siphonage, backflow prevention devices are installed in plumbing systems to ensure that the supply pressure remains higher than the system pressure.

    What's an air gap in plumbing? - ProProfs

    What's an air gap in plumbing?

    • It's the unobstructed horizontal space between the water outlet and the flood level of a fixture.

    • It's the obstructed vertical space between the water outlet and the flood level of a fixture.

    • It's the unobstructed vertical space between the water outlet and the flood level of a fixture.

    • It's the obstructed horizontal space between the water outlet and the flood level of a fixture.

    Correct Answer
    A. It's the unobstructed vertical space between the water outlet and the flood level of a fixture.
    Explanation
    An air gap in plumbing refers to the unobstructed vertical space between the water outlet and the flood level of a fixture. This means that there is a gap between the water outlet and the highest point that water can reach in the fixture, ensuring that there is no direct connection between the water supply and any potential contaminants or pollutants. The air gap acts as a protective barrier, preventing backflow of contaminated water into the clean water supply.

    What's regurgitation? - ProProfs

    What's regurgitation?

    • It's flooding.

    • It's throwing up.

    • It's blood flow in the opposite direction from normal.

    • It's the formation of waves in the ocean.

    Correct Answer
    A. It's throwing up.
    Explanation
    Regurgitation refers to the backward flow of contents from the stomach back into the mouth, often referred to as throwing up or vomiting. This can happen involuntarily due to various causes such as illness, indigestion, or the presence of a foreign body. Regurgitation is a natural bodily response to expel harmful substances or relieve digestive discomfort. It differs from reflux, which involves stomach contents moving back into the esophagus without expulsion.

    What's the other term for a check valve?

    • Water valve

    • Valve

    • Clerk valve

    • Clack valve

    Correct Answer
    A. Clack valve
    Explanation
    The other term for a check valve is a clack valve. A check valve is a type of valve that allows fluid to flow in only one direction, preventing backflow. The term "clack valve" is commonly used to refer to this type of valve, as it describes the sound that the valve makes when it opens and closes.
