1.
Ecotourism means:
Correct Answer
D. Travel
Explanation
Ecotourism refers to a form of responsible travel that focuses on exploring natural environments while minimizing the negative impact on the environment and supporting local communities. It involves activities such as wildlife observation, hiking, and visiting protected areas. This type of tourism aims to promote conservation, educate visitors about the importance of environmental sustainability, and provide economic benefits to local communities.

2.
Mechanical turbulence means:
Correct Answer
A. Irregular Motion
Explanation
Mechanical turbulence refers to the irregular and chaotic motion of air caused by the interaction of wind with obstacles such as buildings, trees, or mountains. This turbulence can result in unpredictable wind patterns, gusts, and eddies, which can have significant impacts on airflow and can affect the stability of aircraft, buildings, and other structures. Therefore, the correct answer is "Irregular Motion."
3.
Methane means:
Correct Answer
D. Flammable Gas
Explanation
Methane is a colorless and odorless gas that is highly flammable. It is the main component of natural gas and is commonly used as a fuel source. Methane is produced by natural processes such as the decomposition of organic matter and is also released during the extraction and transportation of fossil fuels. Due to its flammable nature, methane is used as a fuel for heating, cooking, and electricity generation. Therefore, the correct answer for this question is "Flammable Gas."
4.
Backwashing means:
Correct Answer
A. Reversing Flow
Explanation
Backwashing refers to the process of reversing the flow of water or other fluid through a filter or a similar system in order to clean or remove accumulated debris or contaminants. It is commonly used in water treatment systems or in swimming pool filters to maintain their effectiveness. By reversing the flow, any trapped particles or impurities are dislodged and flushed out, ensuring the system operates efficiently. Therefore, "Reversing Flow" is the correct answer as it accurately defines the term "backwashing".
5.
Glovebag means:
Correct Answer
A. Protective Enclosure
Explanation
Glovebag refers to a protective enclosure used to contain hazardous materials or substances. It is designed to provide a barrier between the user and the potentially harmful materials, ensuring safety during handling or transportation. The term "glovebag" suggests the use of gloves to handle the enclosed materials, further emphasizing its protective nature.
6.
Ozone hole means:
Correct Answer
C. Break In Stratosphere
Explanation
The correct answer is "Break In Stratosphere." Ozone hole refers to the thinning or depletion of the ozone layer in the Earth's stratosphere. This depletion allows more ultraviolet (UV) radiation from the sun to reach the Earth's surface, which can have harmful effects on human health and the environment.
7.
Digit means:
Correct Answer
B. Finger
8.
Air curtain means:
Correct Answer
D. Oil Spill Containment
Explanation
An air curtain is a device used to create a barrier of air that separates two different environments. In the context of oil spill containment, an air curtain can be used to prevent the spread of oil by creating a barrier of air that stops the oil from spreading further. This is achieved by blowing a high-velocity stream of air across the surface of the water, creating a barrier that prevents the oil from moving beyond a certain point. This helps to contain the oil spill and minimize its impact on the surrounding environment.
9.
Kinetic energy means:
Correct Answer
C. Motion
Explanation
Kinetic energy refers to the energy possessed by an object due to its motion. It is the energy that an object possesses when it is in motion and is directly proportional to its mass and the square of its velocity. Therefore, the correct answer is "Motion" as it accurately represents the concept of kinetic energy.
10.
Methoxychlor means:
Correct Answer
A. Pesticide
Explanation
Methoxychlor is a term that refers to a pesticide. Pesticides are substances used to control or eliminate pests, such as insects, weeds, or rodents, that can cause damage to crops, livestock, or human health. Methoxychlor is a specific type of pesticide that was commonly used in the past for its insecticidal properties. It was primarily used to control pests in agriculture and as a treatment for lice and scabies in humans and animals. However, due to its harmful effects on the environment and potential health risks, its use has been heavily regulated or banned in many countries.
11.
Intra means:
Correct Answer
D. Within
Explanation
The prefix "intra-" means "within" or "inside." It is commonly used in medical terms to indicate something that is located or occurring within a particular organ or structure. For example, "intravenous" means "within a vein" and "intracranial" means "within the skull." Therefore, the correct answer is "within."
12.
Municipal means:
Correct Answer
B. From A Community
Explanation
The term "municipal" refers to something related to a city or a local community. It is used to describe things that are associated with the governing body or administration of a specific locality or community. Therefore, the correct answer is "From A Community".
13.
Sediment means:
Correct Answer
D. Topsoil Particles
Explanation
Sediment refers to the particles of soil or rock that are carried and deposited by wind, water, or ice. These particles settle at the bottom of bodies of water or accumulate on land, forming layers of topsoil. Therefore, the correct answer is "Topsoil Particles."
14.
Point source means:
Correct Answer
A. Fixed Location
Explanation
Point source refers to a fixed location from which a specific phenomenon or substance originates. It implies that the source is stationary and does not move. In the context of the given options, "Fixed Location" best describes point source as it aligns with the concept of a specific location being the origin of something. "Release" could also be a possible answer, but it is not as precise as "Fixed Location" in conveying the stationary nature of the source. "Dense Fog" and "Tissue Reaction" are unrelated and do not define point source.
15.
Hybrid means:
Correct Answer
A. Cross-Bred
Explanation
Hybrid refers to the process of cross-breeding two different species or varieties to create a new offspring with desirable traits from both parents. This term is commonly used in the field of genetics and agriculture to describe the breeding of plants or animals with specific characteristics. Therefore, "Cross-Bred" is an appropriate explanation for the term "Hybrid" as it accurately describes the process of combining different genetic material to create a new hybrid offspring.
