2. Water Table Depletion

3. Riverbed Degradation

How many of the above environmental damages are caused by illegal sand mining?

(a) Only one

(b) Only two

(c) all three

(d) none

Explanation

– Illegal Sand Mining Causes Environmental Damage Such As Riverbed Degradation, Loss of Aquatic Habitat, Increased Turbidity, Water Table Depletion, Soil Erosion, Flooding, Infrastructure Damage, Loss of Fertile Land, Negative Impact On Local Ecosytms, Decreased water quality, and a risk to the ecological Balance of the Riverine Regime.

Therefore, option (c) is the correct answer.

Question 2

With reference to the fluoride content in the groundwater, consider the following statements:

1. Tamil nadu has the maximum fluoride content in groundwater.

2. Fluoride Contamination Over 1.50mg/Litre is deemed unfit for drinking purposes.

Which of the statements give above is/are correct?

(a) 1 Only

(b) 2 Only

(c) Both 1 and 2

(d) neater 1 nor 2

Explanation

– Excess Fluoride Increases the risks of disease conditions like skeletal fluorosis, accelerates of the rate of decay and can cause others Human Health Hazards, especically among children.

– Even thought fluoride is Among the many minerals found naturally in the groundwater, the nationally permissible limit is 1.50 milligrams/litre. Contamination over 1.50mg/litre is deemed unfit for drinking purposes. Hence, Statement 2 is Correct.

-Fluoride is discharged and mixed with the groundwater as a result of the leaching and dissolving of fluoriding minerals in the host water aquifers.

– The average fluoride concentration in the groundwater was greater in dry, western indian area. Rajasthan Toopped the charts, with pre-minsoon concentrations of 1.41mg/litre and post-minsoon concentrations of 1.44mg/litre, bot Hence, Statement 1 is not correct.

Therefore, option (b) is the correct answer.

Question 3

With reference to the primates, consider the following statements:

1. Female dominance in many primate groups development through reproductive control rather than physical prowess.

2. Male dominance is common in primate social.

Which of the statements give above is/are correct?

(a) 1 Only

(b) 2 Only

(c) Both 1 and 2

(d) neater 1 nor 2

Explanation

– A new study semes to suggest that Male Dominance is rare In primate socialies, as most species have females holding equal or more power. Hence, Statement 2 is not correct.

-The study, ‘The evolution of Male-Female Dominance Relationships in Primate Societies’, semes to break long-standing assets about gender roles. Published in the proceedings of the National Academy of Science (PNAS), The groundbreaking study has changed our understanding of gender and power dynamics in the animal kingdom.

– Overall, the Researchers discovered that Male Dominance Occurred in Only 25 of 151 Groups, With Males Winning More than 90% of Bouts Against the Other Sex. Only 16 Communities Had Female Domination, While the remaining 70% of tribes had no dominant sex or only minor dominance.

– The study also calls into question the idea that force is always the foundation of power. Female dominance in many primate communities arises from reproductive control rather than physical prowess. Hence, Statement 1 is Correct.

– Male dominance can be evident in terrestrial species (where Strength is Important), sexually dimorphic species (Groups with Larger, Stronger Men), and Polygyn Societies (bless maals compette).

Therefore, option (a) is the correct answer.

Question 4

Which of the following species can withstand temperatures up to 100 degrees Celsius?

1. Thermophiles

2. Tardigrades

3. Pompeii worm

Select the Correct Answer Using the Codes Given Below:

(a) 1 and 2 only

(b) 2 Only

(c) 1, 2 and 3

(d) 3 only

Explanation

Pompeii worm

-Found hanging around deep-sea hydrothermal vents, The pompeii worm doesnch at flinch at boiling water. It lives in the people where the temperature can go up to 105 ° C.

– These things have bading on their backs, acting as a heat shield. It’s a strange but genius partnership: The Bacteria help the worm survive, and in return, they get a cosy home.

Tardigrades

– If there was a “Toughest creature alive” contest, tardigrades would probably win. These microscopic animals can survive Nearly anything – Freezing Cold, Extreme Heat (up to 150 ° C), Radiation, Dehydration, and Even Oouter Space, According to Scientific Experiments.

Heat-loving microbes (thermophiles)

– Some of them thrive in boiling geysers or hot springs at over 120 ° C. One Particular Species, Nicknamed “Strain 121,” Survives at Autoclave temperatures (121 ° C).

Therefore, option (c) is the correct answer.

Question 5

Rat-hole mining is prevalent in:

(a) sikkim

(b) Jammu and Kashmir

(c) kerala

(d) meghalaya

Explanation

-Rat-hole mining, a method of extraction coal from narrow, horizontal seams, is Common in meghalaya. The term “rat hole” refers to narrow pits dug into the ground, usulaly large enough for one person to descend and extract coal.

– After digging the pits, miners use ropes or bamboo ladders to descend to the coal seams. The coal is then physically removed with rudimentary instruments like pickaxes, shovels, and baskets.

– Rat hole mining causes severe safety and environmental risks. Mines are of unregulated, with no safety measures sufficient ventilation, structural support, or worker protective equipment. Furthermore, the mining process can result in land degradation, deforestation, and water contamination.

Therefore, option (d) is the correct answer.

Question 6

With reference to biofuel, consider the following statements:

1. Sugarcane-Based Ethanol Results in Overall Negative Greenhouse Gas (GHG) Emissions.

2. The use of maize for biofuel has turned India from an import to surplus production and exporter of the feed grain.

Which of the above give statements is/are true?

(a) 1 Only

(b) 2 Only

(c) Both 1 and 2

(d) neater 1 nor 2

Explanation

– Bioethanol can be easy generated from sugarcane, beet juice, rice, maize, and other grains. Notably, the use of maize for biofuel has turned from a surplus product and exporter to an important grain. At the same time, debates are on allowing imports of genetically modified maize for Ethanol Production.

– The us is the largest producer of Ethanol, with more than 16 billion gallons produced in 2024. This is followed by brazil. While Ethanol produced in the us is primarily produced from corn, Brazil mainly produces its ethanol from sugarcane. In 2022, India also reached a record landmark of production more than one billion gallons of ethanol and now contributing around 5 per cent to the total global Ethanol Production.

– Compared to the us, Ethanol Produced in Brazil has a low environment impact due to integrated processing: Waste bagasse from Sugarcane is used to Generate Power for Distileres; Molasses are used for cattle feed; Surplus bagasse is pressed with binder to Produce Boards and Construction Material; And boiler ash services as a source of phosphate.

Therefore, option (a) is the correct answer.
