Which of the following is NOT a common heavy metal found in contaminated environments?

  1. Lead

  2. Mercury

  3. Chromium

  4. Aluminum


Correct Option: D
Explanation:

Aluminum is not typically considered a heavy metal due to its low toxicity and abundance in the Earth's crust.

What is the primary mechanism by which plants accumulate heavy metals from the soil?

  1. Active transport

  2. Passive transport

  3. Chelation

  4. Ion exchange


Correct Option: B
Explanation:

Plants primarily accumulate heavy metals through passive transport, where metals enter the plant's roots along with water and nutrients.

Which of the following is NOT a common type of bacteria used in bioremediation of heavy metals?

  1. Pseudomonas

  2. Bacillus

  3. Escherichia coli

  4. Rhizobium


Correct Option: C
Explanation:

Escherichia coli is not typically used in bioremediation of heavy metals due to its limited ability to tolerate and accumulate metals.

What is the process by which microorganisms convert toxic heavy metals into less harmful forms?

  1. Bioaccumulation

  2. Biotransformation

  3. Biodegradation

  4. Bioremediation


Correct Option: B
Explanation:

Biotransformation is the process by which microorganisms convert toxic heavy metals into less harmful forms through enzymatic reactions.

Which of the following is NOT a common technique used in bioremediation of heavy metals?

  1. Phytoremediation

  2. Bioaugmentation

  3. Biosorption

  4. Bioventing


Correct Option: D
Explanation:

Bioventing is a technique used to remediate volatile organic compounds, not heavy metals.

What is the term used to describe the ability of certain plants to accumulate and tolerate high levels of heavy metals?

  1. Hyperaccumulation

  2. Phytoextraction

  3. Phytoremediation

  4. Bioremediation


Correct Option: A
Explanation:

Hyperaccumulation is the ability of certain plants to accumulate and tolerate high levels of heavy metals in their tissues.

Which of the following is NOT a common type of fungus used in bioremediation of heavy metals?

  1. Aspergillus

  2. Penicillium

  3. Trichoderma

  4. Saccharomyces


Correct Option: D
Explanation:

Saccharomyces is a type of yeast, not a fungus, and is not typically used in bioremediation of heavy metals.

What is the term used to describe the process of using microorganisms to remove heavy metals from contaminated water?

  1. Bioremediation

  2. Phytoremediation

  3. Bioaugmentation

  4. Biosorption


Correct Option: A
Explanation:

Bioremediation is the process of using microorganisms to remove contaminants, including heavy metals, from the environment.

Which of the following is NOT a common type of algae used in bioremediation of heavy metals?

  1. Chlorella

  2. Spirulina

  3. Scenedesmus

  4. Euglena


Correct Option: D
Explanation:

Euglena is a type of protozoan, not an algae, and is not typically used in bioremediation of heavy metals.

What is the term used to describe the process of using plants to remove heavy metals from contaminated soil?

  1. Phytoremediation

  2. Bioremediation

  3. Bioaugmentation

  4. Biosorption


Correct Option: A
Explanation:

Phytoremediation is the process of using plants to remove contaminants, including heavy metals, from the soil.

Which of the following is NOT a common type of bacteria used in bioremediation of heavy metals?

  1. Pseudomonas

  2. Bacillus

  3. Escherichia coli

  4. Rhizobium


Correct Option: C
Explanation:

Escherichia coli is not typically used in bioremediation of heavy metals due to its limited ability to tolerate and accumulate metals.

Which of the following is NOT a common type of fungus used in bioremediation of heavy metals?

  1. Aspergillus

  2. Penicillium

  3. Trichoderma

  4. Saccharomyces


Correct Option: D
Explanation:

Saccharomyces is a type of yeast, not a fungus, and is not typically used in bioremediation of heavy metals.
