Bioremediation is used when microorganisms are put into a polluted area and do what?
- A.
Destroy the pollutants to purify the air, water or soil!
- B.
Turn dangerous hydrocarbons into smaller harmless by-products!
- C.
Create CO2 and Inorganic Salts!
- D.
All Of The Above
Correct Answer
D. All Of The AboveExplanation
Bioremediation is a process where microorganisms are introduced into a polluted area to break down and remove pollutants. These microorganisms can destroy pollutants, such as harmful chemicals or hydrocarbons, and convert them into smaller, harmless by-products. Additionally, during bioremediation, microorganisms can also produce CO2 and inorganic salts as part of their metabolic processes. Therefore, all of the given options are correct, as bioremediation can help purify the air, water, and soil by destroying pollutants, converting dangerous hydrocarbons, and producing CO2 and inorganic salts.Rate this question:

Okay that last one was easy...let's get a little more in depth!What did people use to treat water several hundreds of years ago?
- A.
Used bioremediation to allow microorganisms to purify their water
- B.
Nothing!
- C.
Used intricate waterway systems to purify it at a common location such as the common sewage plant
- D.
Used chlorine to purify their water
Correct Answer
B. Nothing!Explanation
The Correct answer is B! It was not until the 1800s that sewage systems were introduced, and not until the 1960s till bioremediation was introduced!Rate this question:

Ok...here's where it gets toughWhat does the term UVGI stand for?
- A.
Ultra Versatile Gaseous Irrigation
- B.
Ultraviolet Gaseous Irrigation
- C.
Underwater Vehicle for Gaseous Interpretation
- D.
Ultraviolet Germ Irritator
- E.
Ultraviolet Germicidal Irradiation
Correct Answer
E. Ultraviolet Germicidal IrradiationExplanation
UVGI stands for Ultraviolet Germicidal Irradiation. This term refers to the use of ultraviolet (UV) light to kill or inactivate microorganisms, such as bacteria, viruses, and molds. UVGI is commonly used in air purification systems, water treatment, and surface disinfection to reduce the spread of infectious diseases. The UV light damages the genetic material of microorganisms, preventing them from reproducing and causing harm. Therefore, Ultraviolet Germicidal Irradiation is the correct answer as it accurately describes the process and purpose of using UV light for germicidal purposes.Rate this question:

Let's Try something different! Fill in the blank for the following questions...__ _______ soil treatment is the process of removing soil from the ground and treating it at an outside location, such as a bioreactor.
Correct Answer
Ex SituExplanation
Ex Situ soil treatment refers to the process of removing soil from its original location and treating it at a different site, such as a bioreactor. This method is used when the contaminated soil cannot be effectively treated in situ, or in its original place. Ex Situ treatment allows for better control and management of the treatment process, as well as the ability to treat larger volumes of soil. It can involve various techniques such as bioremediation, thermal desorption, or soil washing, depending on the specific contaminants present in the soil.Rate this question:

A ___________ is a system that lets dirty or waste air in, and allows microorganisms to grow in a pool of water that is being constantly moved around by oxygen being pushed in from below.
Correct Answer
biofilter
bioscrubberExplanation
A biofilter or bioscrubber is a system that allows dirty or waste air to enter and facilitates the growth of microorganisms in a pool of water. These microorganisms break down pollutants present in the air, purifying it. The water in the system is constantly moved around by oxygen being pushed in from below, creating an optimal environment for the microorganisms to thrive and efficiently remove pollutants from the air. Both biofilters and bioscrubbers serve the same purpose of air purification through biological processes.Rate this question:

______________ is a possible byproduct of bioremediation, when the microorganisms break the harmful materials down!
Correct Answer
CO2
Smaller hydrocarbon chains
inorganic saltsExplanation
During bioremediation, microorganisms break down harmful materials. This process can result in the production of CO2, smaller hydrocarbon chains, and inorganic salts as byproducts.Rate this question:

Alright back to some multiple choice! Just to keep you on your toes!What would be the least expensive, but more time consuming way to purify a field where petroleum has leaked in to the soil?
- A.
Ex Situ Soil Treatment
- B.
Bioscrubbers
- C.
In Situ Soil Treatment
- D.
Biofilters
- E.
None Of The Above
Correct Answer
C. In Situ Soil TreatmentExplanation
In situ soil treatment refers to the process of treating contaminated soil without removing it from its original location. This method is considered the least expensive because it eliminates the need for excavation and transportation of soil. However, it is more time-consuming compared to ex situ soil treatment methods. In situ soil treatment involves the use of various techniques such as bioremediation, phytoremediation, or chemical oxidation to break down or remove the contaminants in the soil over time. This allows for natural degradation or transformation of the pollutants, reducing the overall cost but requiring a longer duration for complete purification.Rate this question:

What are some of the effects of living in an area where air is not or minimally purified?
- A.
Shorter Life Expectancy
- B.
Better Quality Of Life
- C.
Higher Disease And Sickness Raye
- D.
All Of The Above
- E.
Just A and C
Correct Answer
E. Just A and CExplanation
Living in an area where air is not or minimally purified can have several negative effects on health. Shorter life expectancy is one of these effects, as exposure to pollutants in the air can lead to respiratory problems and other illnesses that can shorten one's lifespan. Additionally, higher disease and sickness rates are another consequence, as the presence of pollutants in the air can weaken the immune system and make individuals more susceptible to infections and diseases. Therefore, the correct answer is "Just A and C" because both shorter life expectancy and higher disease and sickness rates are effects of living in an area with poor air quality.Rate this question:

Which bodies of water, contain bioremediated waste water?
- A.
Just Lakes
- B.
Just Oceans
- C.
Just Rivers
- D.
All Of The Above
- E.
Just A and B
Correct Answer
D. All Of The AboveExplanation
The correct answer is "All Of The Above" because bioremediation is a process that uses microorganisms to break down and remove pollutants from water. This process can be applied to various bodies of water, including lakes, oceans, and rivers. Therefore, all of these bodies of water have the potential to contain bioremediated waste water.Rate this question:
