Answer: a

Explanation:

Recently, the Union Minister for Petroleum and Natural Gas launched E85 fuel at an IndianOil retail outlet in New Delhi. 

• It is a high-ethanol blended fuel comprising 80–85 per cent ethanol and 14–19 per cent petrol, specifically designed for use in flex-fuel vehicles.
• The initiative aims to facilitate the adoption of Flex-Fuel Vehicles (FFVs), which are capable of operating on ethanol blends from E20 to E100, without restricting consumers to a single blend.
• Benefits of E85 Fuel:
  • Lower Price: E85 is priced lower than conventional petrol to ensure that the economic benefits of domestically produced ethanol are passed on to consumers.
  • Reduce lifecycle Greenhouse gas: Flex-fuel vehicles operating on E85 can reduce lifecycle greenhouse gas emissions by around 61 per cent compared to conventional petrol vehicles.
  • Knock Resistance: With a Research Octane Number (RON) of about 108,  ethanol offers superior knock resistance that allows engines to operate at higher compression ratios and optimized ignition timing.
  • Cleaner Combustion: Higher ethanol blends promote cleaner and more complete combustion, resulting in near-zero particulate matter emissions contributing to improved urban air quality.

Hence only statement 1 is correct.

Answer: b

Explanation:

Recently, scientists at Agharkar Research Institute (ARI), Pune have discovered a new species of Foraminifera and named it as Portatrochammina bharatensis.

• It is a group of single-celled organisms that have inhabited the world’s oceans for over 500 million years.
• The shells have hundreds of tiny holes called foramen, the Latin word for window. 
• They are among the most abundant and ecologically important organisms in the ocean.
• Features of Foraminifera:
  • Size: They are generally sand-grain size, measuring between 500 and 50 µm.
  • Habitat: They live in the open ocean, along the coasts, and in estuaries.
  • Most have shells for protection and either float in the water column (planktonic) or live on the sea floor (benthic). 
  • They construct their intricate shells, called “tests,” from materials they scavenge from their surroundings (agglutinating mineral grains). 
  • The most of foraminifera” ‘crawl around’ using their pseudopodia.
  • They don’t have a wall around their cell membranes, they are extremely flexible and can change shape.
  • The organism pushes extensions of its cytoplasm called pseudopodia (or false feet) through these holes to gather food.
  • Diet: Foraminifera eat detritus on the sea floor and anything smaller than them: diatoms, bacteria, algae, and even small animals such as tiny copepods.
  • They build complex shells, consisting at their simplest of one chamber (like a vase or tube) to many chambers that coil in elaborate ways.

Hence only statements 1 and 2 are correct.

Answer: c

Explanation:

Researchers from the Indian Institute of Astrophysics (IIA) have used over 100 years of observations from the Kodaikanal solar observatory to investigate how large cellular structures known as supergranulations behave during different phases of the solar cycle.

• It describes an approximately 11-year cycle of solar activity driven by the sun’s magnetic field.
• It is indicated by the frequency and intensity of sunspots visible on the surface. 
• Every 11 years or so, the Sun’s magnetic field completely flips.
• This means that the Sun’s north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles to flip back again.
• The solar cycle affects activity on the surface of the Sun, such as sunspots, which are caused by the Sun’s magnetic fields.
• As the magnetic fields change, so does the amount of activity on the Sun’s surface.
• It can be tracked by counting the number of sunspots.
• Cycle Stages:
  • Solar minimum: It is the beginning of a solar cycle or when the Sun has the least sunspots.
  • Solar maximum: It is the middle of the solar cycle or when the Sun has the most sunspots.
  • As the cycle ends, it fades back to the solar minimum, and then a new cycle begins.
• Impact: The solar cycle has the potential to impact Earth’s climatic conditions through changes in solar radiation, cosmic rays, and ozone distribution.

What is Sun’s supergranulation?

• The Sun’s supergranulation refers to a physical pattern covering the surface of the quiet Sun with a typical horizontal scale of approximately 30,000 km and a lifetime of around 1.8 d.
• Supergranulation was discovered by Hart (1954) using Doppler images of the Sun.

Hence both statements are correct.
