Septic tank means:
- A.
  
  Combustion Chamber
- B.
  
  Underground Storage Tank
- C.
  
  Heavy Particles
- D.
  
  Oil Drum
Correct Answer
B. Underground Storage Tank

Explanation
Septic tank refers to an underground storage tank used for the treatment and disposal of sewage and wastewater. It is designed to separate and decompose solid waste, allowing the liquid effluent to be discharged into the soil for further filtration and purification. This system is commonly used in residential and rural areas where there is no access to a centralized sewage system. The septic tank provides an efficient and environmentally friendly method of managing wastewater, ensuring the protection of public health and the environment.

- B.
  
  Jet Stream
- C.
  
  Riverbed
- D.
  
  Reduced Pollutants
Correct Answer
D. Reduced Pollutants

Explanation
Pretreatment refers to the process of reducing or removing pollutants from a substance or environment before it undergoes further treatment or enters a system.

River basin means:
- A.
  
  Less Than
- B.
  
  Land Exposed By River
- C.
  
  Solid Waste
- D.
  
  Drought
Correct Answer
B. Land Exposed By River

Explanation
River basin refers to the land area that is drained by a river and its tributaries. It includes all the land that is exposed and affected by the river's flow and water drainage. This land is often lower in elevation and slopes towards the river, allowing water to flow into it. The river basin acts as a natural boundary for the river's water flow and plays a crucial role in the water cycle, as it collects and channels water from precipitation and runoff.

Correct Answer
C. Copy

Explanation
The word "clone" refers to creating an identical or nearly identical copy of something. It is commonly used in the context of biology and technology to describe the replication of organisms or objects with the same genetic or functional characteristics. In this case, "copy" is the best synonym for "clone" as it accurately captures the concept of making a duplicate or reproduction of something.

Protoplast means:
- A.
  
  Will Not Burn
- B.
  
  Plant Cells
- C.
  
  Disease Causing
- D.
  
  Salt Removal
Correct Answer
B. Plant Cells

Explanation
The term "protoplast" refers to the living part of a plant cell that includes the plasma membrane and its contents, such as the cytoplasm and organelles. Protoplasts are commonly used in plant research and biotechnology to study cell biology, genetic engineering, and cell fusion. They are isolated by removing the cell wall, leaving behind the protoplast. Therefore, the correct answer for this question is "Plant Cells."

Axis means:
- A.
  
  Capacity
- B.
  
  Depth
- C.
  
  Vibration
- D.
  
  Center Of Motion
Correct Answer
D. Center Of Motion

Explanation
Axis means the center of motion around which an object rotates or revolves. It is a fixed point or line that acts as a reference for the movement of an object. In physics and mechanics, the axis is an essential concept to understand the rotational motion of objects. It helps determine the direction and orientation of the object as it moves around the axis.

Codon means:
- A.
  
  Cleaning Agent
- B.
  
  Three Nucleotides
- C.
  
  Community
- D.
  
  Salt Residue
Correct Answer
B. Three Nucleotides

Explanation
A codon is a sequence of three nucleotides that corresponds to a specific amino acid or serves as a start or stop signal for protein synthesis. In genetics, codons are the basic units of the genetic code, and they determine the order of amino acids in a protein. Each codon represents a specific amino acid or a signal to start or stop protein synthesis. Therefore, the correct answer is "Three Nucleotides."

Halon means:
- A.
  
  Animal Population
- B.
  
  Pesticide
- C.
  
  Caught For Sport
- D.
  
  Ozone Depletor
Correct Answer
D. Ozone Depletor

Explanation
Halon is a term that refers to a group of chemicals known as halocarbons, which were commonly used in fire extinguishers and fire suppression systems. These chemicals have the ability to deplete the ozone layer in the Earth's atmosphere. Therefore, the correct answer for this question is "Ozone Depletor."

Germplasm means:
- A.
  
  Genetic Material
- B.
  
  Will Not Burn
- C.
  
  Fruit Eating
- D.
  
  Climate Change
Correct Answer
A. Genetic Material

Explanation
Germplasm refers to the genetic material of an organism, including its DNA and genes. It encompasses the heritable traits and characteristics that can be passed on to future generations. This term is commonly used in the field of agriculture and plant breeding, where germplasm is collected and preserved for the purpose of maintaining biodiversity and improving crop varieties. Germplasm serves as a valuable resource for scientists and breeders to study and manipulate genes, ultimately contributing to the development of new and improved plant varieties.

Stabilization pond means:
- A.
  
  Gravity
- B.
  
  Lagoon
- C.
  
  Smokestack
- D.
  
  Carbon
Correct Answer
B. Lagoon

Explanation
A stabilization pond refers to a lagoon. This is a human-made body of water that is used for the treatment of wastewater. The wastewater is allowed to flow into the lagoon, where natural processes such as sunlight, oxygen, and bacteria help to break down and remove pollutants. The lagoon provides a controlled environment for this treatment process, allowing the water to gradually become cleaner before it is released back into the environment.

Isotope means:
- A.
  
  Sulfur
- B.
  
  Toxic Agent
- C.
  
  Varied Element
- D.
  
  Radiation
Correct Answer
C. Varied Element

Explanation
Isotope means a varied element. Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons. This results in isotopes having different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon, with carbon-12 having 6 neutrons and carbon-14 having 8 neutrons. Isotopes can have different physical and chemical properties due to their varying atomic masses, but they still belong to the same element.

Correct Answer
D. Expels Active Ingredient

Explanation
Propellant refers to a substance used in aerosol cans or similar devices to expel the active ingredient. It is responsible for creating pressure within the container, which forces the active ingredient out when the can is activated. The propellant does not have any therapeutic or medicinal properties itself, but it plays a crucial role in delivering the active ingredient to the desired target.

- D.
  
  Milkweed
Correct Answer
B. Bog

Explanation
Pocosin refers to a bog, which is a type of wetland characterized by acidic, waterlogged soil. Bogs are typically found in areas with high rainfall and low nutrient levels, resulting in the accumulation of decomposed plant material over time. Pocosins are important ecosystems that support unique plant and animal species adapted to the harsh conditions of the bog environment. Therefore, the correct answer is "Bog".
