1, 2, 4 and 5
1,3 and 4 only
2, 3 and 5 only
1, 2, 3, 4 and 5
The question asks to identify the correct statements regarding "The Climate Group" and its initiatives, specifically EP100, and the role of the International Energy Agency (IEA). We need to evaluate each statement individually based on factual knowledge about these organizations and initiatives.
B) 1, 3 and 4 only
Based on the evaluation, statements 1, 3, and 4 are correct, while statements 2 and 5 are incorrect.
The question uses an analogy comparing wetlands to the kidneys of the Earth. Kidneys in the human body are responsible for filtering waste products from the blood. We need to identify which function of wetlands best matches this filtering and cleansing role.
Correct Option: D) Aquatic plants absorb heavy metals and excess nutrients.
This function directly parallels the role of kidneys in filtering out waste products and maintaining the purity of bodily fluids. Wetlands act as natural filters, removing pollutants and excess nutrients from water as it flows through them, thus purifying the water.
In the context of WHO Air Quality Guidelines. consider following the statements:
1. The 24-hour mean of PM2.5 should not exceed 15 µg/m3 and the annual mean of PM2.5 should not exceed 5 µg/m3
2. In a year, the highest levels of ozone pollution occur during periods of inclement weather.
3. PM10 can penetrate the lung barrier and enter the bloodstream.
4. Excessive ozone in the air can trigger asthma.
Which of the statements given above are correct?
The question asks us to identify the correct statements regarding WHO Air Quality Guidelines and the effects of air pollutants. We need to evaluate each statement based on current scientific understanding and WHO recommendations.
Based on the evaluation, statements 1 and 4 are correct.
Correct Option: B) 1 and 4 only
With reference to "Gucchi" sometimes mentioned in the news, consider the following statements:
1. It is a fungus.
2. It grows in some Himalayan forest areas.
3. It is commercially cultivated in the Himalayan foothills of north-eastern India.
Which of the statements given above is/are correct?
The question asks to identify the correct statements about "Gucchi", a term sometimes mentioned in the news. We need to evaluate each statement based on general knowledge about Gucchi mushrooms.
Statement 1: It is a fungus. Gucchi (Morchella esculenta) is indeed a type of mushroom, which belongs to the kingdom Fungi. It is a highly prized edible fungus. So, statement 1 is correct.
Statement 2: It grows in some Himalayan forest areas. Gucchi mushrooms are known to grow in the temperate forests of the Himalayas, particularly in regions like Jammu and Kashmir, Himachal Pradesh, and Uttarakhand. They thrive in specific environmental conditions found in these high-altitude areas. So, statement 2 is correct.
Statement 3: It is commercially cultivated in the Himalayan foothills of north-eastern India. Gucchi mushrooms are wild mushrooms that are extremely difficult to cultivate commercially. Despite extensive research, large-scale commercial cultivation has not been successful due to their complex growth requirements and symbiotic relationships. They are primarily collected from the wild. Therefore, statement 3 is incorrect.
Based on the evaluation, statements 1 and 2 are correct, while statement 3 is incorrect.
Correct Option: C) 1 and 2
With reference to polyethylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements:
1. Its fibers can be blended with wool and cotton fibers to reinforce their properties.
2. Containers made of it can be used to store any alcoholic beverage.
3. Bottles made of it can be recycled into other products.
4. Articles made of it can be easily disposed of by incineration without causing greenhouse gas emissions.
Which of the statements given above are correct?
The question asks us to identify the correct statements regarding polyethylene terephthalate (PET). We need to evaluate each statement based on the known properties and uses of PET.
Based on the analysis, statements 1 and 3 are correct.
Correct Option: A) 1 and 3
The question asks to identify which of the given options is NOT a bird. This requires knowledge of the classification of the animals listed in the options.
Correct Option: A) Golden Mahseer is a species of fish, not a bird.
Which of the following are nitrogen-fixing plants?
1. Alfalfa
2. Amaranth
3. Chickpea
4. Clover
5. Purslane (Kulfa)
6. Spinach
Select the correct answer using the code given below:
1, 3 and 4 only
1, 3, 5 and 6 only
2, 4, 5 and 6 only
1, 2, 4, 5 and 6
The question asks to identify nitrogen-fixing plants from a given list. Nitrogen fixation is a process by which atmospheric nitrogen is converted into ammonia or other nitrogenous compounds, primarily by microorganisms in the soil or associated with plant roots. Leguminous plants are well-known for their symbiotic relationship with nitrogen-fixing bacteria (Rhizobia).
Correct Option: A) 1, 3 and 4 only
The question asks about the application of "Biorock technology". To answer this, one needs to know what Biorock technology is primarily used for.
Correct Option: A) Restoration of damaged coral reefs
Biorock technology is specifically designed for marine ecosystem restoration, with a significant focus on coral reefs. It involves placing metal structures in the ocean and running a small electrical current through them. This causes minerals dissolved in the seawater to precipitate and form a limestone-like material on the structures. This material provides an ideal substrate for corals to attach and grow much faster than they would naturally, aiding in the recovery of damaged reefs.
The question asks about the well-known application of the "Miyawaki method." This requires knowledge of environmental and ecological techniques, specifically the Miyawaki method, which is a popular technique for afforestation.
Correct Option: C) The Miyawaki method is renowned for its application in creating mini forests in urban areas. It involves planting native species densely to foster rapid forest growth, enhancing biodiversity and ecological benefits in confined spaces.
