Answer: d

Explanation:

Researchers at the University of Utah have found that freshwater saturates the rock and sediment beneath the Great Salt Lake to depths of up to 13,000 feet. 

• Location: It is a saline lake located in northern Utah, United States.
• It is the largest inland body of salt water in the Western Hemisphere and one of the most saline inland bodies of water in the world.
• Water Source: The lake is fed by the Bear, Weber, and Jordan rivers and has no outlet.
• The lake has fluctuated greatly in size, depending on the rates of evaporation and the flow of the rivers that feed it. 
  • Like the Dead Sea, the Great Salt Lake exists within an arid environment and has chemical characteristics similar to that of the oceans. 
• Formation and Salinity: It has a much greater salinity than the oceans, however, since natural evaporation exceeds the supply of water from the rivers feeding the lake.
• It is surrounded by great stretches of sand, salt land, and marsh, the Great Salt Lake remains eerily isolated from the nearby cities, towns, and other human habitations.
• Fauna: Some notable avian species that are found here include American avocet, Wilson’s phalarope, California gull, black-necked stilt, American white pelican, peregrine falcon, marbled godwit, etc.

Hence option (d) is the correct answer.

Answer: c

Explanation:

According to a new international study led by researchers at the University of Birmingham, Beavers can engineer riverbeds into promising ways to prevent carbon dioxide release into the air.

• The beaver, from the genus Castor, includes two amphibious rodent species.
• They are semi-aquatic species.
• Habitat: They live in streams, marshes, rivers, and ponds, and along the shorelines of large lakes
• Distribution: They are native to North America, Europe, and Asia.
• Characteristics of Beaver:
  • Beavers have long, orange, visible front teeth, called incisors. These teeth grow continuously throughout its life and are worn down through daily use. 
  • Lifespan: They typically live 10 to 12 years. 
  • Communication: One important communication signal among beavers is a tail slap on the surface of the water, indicating danger. Typically performed by an adult
  • They are known as “ecosystem engineers” because they construct dams of branches, stones, and mud in streams, rivers, marshes, and ponds.
  • These beaver ponds which the animals use as sources of food, as well as protection from predators.
• Conservation Status:
• IUCN Red List: Least Concern

Hence both statements are correct

Answer: b

Explanation:

India’s semiconductor and printed circuit board (PCB) industry is bracing for potential disruption in helium supplies after Iran’s attack on Qatar’s Ras Laffan LNG hub.

• It is an inert gas and does not react with other substances or combust.
• It was discovered in 1868 by Jules Janssen and Norman Lockyervia a yellow spectral line during a solar eclipse. 
• Named after the Greek word ‘Helios’, meaning Sun.
• Properties of Helium:
  • Its atomic number is 2, making it the second lightest element after hydrogen.
  • Helium also has a very low boiling point (-268.9° C), allowing it to remain a gas even in super-cold environments.
  • The gas is non-toxic, but cannot be breathed on its own, because it displaces the oxygen humans need for respiration.
  • It is the only element that cannot be solidified by sufficient cooling at normal atmospheric pressure.
• Largest global reserves: United States, Algeria, and Russia.
• India’s Rajmahal Volcanic Basin (Jharkhand) is a significant helium reservoir trapped for billions of years.
• Applications of Helium:
  • Pressurizing Fuel Tank: It is used to pressurize fuel tanks, ensuring fuel flows to the rocket’s engines without interruption.
  • Cooling systems: It is used in cooling systems of rockets.

Hence only statements 2 and 3 are correct.
