The settled and floating materials are removed by this treatment method.
-
Primary treatment
-
Secondary treatment
-
Tertiary treatment
-
Peripheral treatment
Correct Answer
A. Primary treatmentExplanation
Primary treatment is the initial step in wastewater treatment where settled and floating materials are removed. This process involves physical methods such as screening, sedimentation, and flotation to separate solid particles and debris from the wastewater. The primary treatment helps to reduce the organic load and remove large solids, which improves the efficiency of subsequent treatment processes.Rate this question:

Which is a non-renewable resource?
-
Coal
-
Petroleum
-
Natural gas
-
All the above
Correct Answer
A. All the aboveExplanation
Coal, petroleum, and natural gas are all examples of non-renewable resources. Non-renewable resources are finite and cannot be replenished within a human lifespan. These resources are formed over millions of years through geological processes and their extraction and consumption rates far exceed their natural replenishment rate. As a result, these resources are being depleted faster than they can be replaced. Once these resources are exhausted, they cannot be easily replaced, making them non-renewable.Rate this question:

----------- is the chief component of natural gas.
-
Ethane
-
Methane
-
Propane
-
Butane
Correct Answer
A. MethaneExplanation
Methane is the chief component of natural gas. Natural gas is primarily composed of methane, with smaller amounts of other hydrocarbon gases such as ethane, propane, and butane. Methane is the main component because it is the simplest hydrocarbon, consisting of a single carbon atom bonded to four hydrogen atoms. It is highly flammable and is commonly used as a fuel for heating and cooking purposes.Rate this question:

Odd one out. bio alcohol, green diesel, bio ethers, petroleum
-
Bio alcohol
-
Green diesel
-
Bio ethers
-
Petroleum
Correct Answer
A. PetroleumExplanation
The odd one out in this group is petroleum. The other three options (bio alcohol, green diesel, bio ethers) are all forms of renewable or alternative fuels, while petroleum is a fossil fuel.Rate this question:

Odd one out. cholera, typhoid, scabies, dysentery
-
Cholera
-
Typhoid
-
Scabies
-
Dysentery
Correct Answer
A. ScabiesExplanation
The odd one out in this list is scabies because it is the only condition that is caused by a parasitic mite infestation, while the other three options are all infectious diseases caused by bacteria (cholera and typhoid) or a parasite (dysentery).Rate this question:

Pick out the suitable appliances to conserve the electric energy. Florescent bulbs, copper choke, electric water heater, tungsten bulbs
-
Florescent bulbs
-
Copper choke
-
Electric water heater
-
Tungsten bulbs
Correct Answer
A. Florescent bulbsExplanation
Fluorescent bulbs are a suitable appliance to conserve electric energy because they are more energy-efficient compared to tungsten bulbs. Fluorescent bulbs use less electricity to produce the same amount of light as tungsten bulbs, resulting in lower energy consumption and reduced electricity bills. Additionally, fluorescent bulbs have a longer lifespan, reducing the frequency of replacements and further saving energy. Copper choke and electric water heaters are not directly related to conserving electric energy, while tungsten bulbs are known for their high energy consumption.Rate this question:
