1. It belongs to the family Sisoridae and subfamily Glyptosterninae.
2. It was discovered in the hill streams of Chandel district in Manipur, which forms part of the Chindwin-Irrawaddy river drainage system.
3. It is adapted to stagnant freshwater habitats through specialized morphological features.
4. It is considered a bio-indicator of freshwater ecosystem health.

Which of the statements given above are correct?

2. With reference to CNGC13 and systemic alarm signalling in plants, consider the following statements:

1. CNGC13 is a cyclic nucleotide-gated calcium ion channel located in the plasma membrane of plant cells.
2. It facilitates the movement of calcium ions, enabling long-distance transmission of defence signals from damaged leaves to undamaged leaves.
3. Glutamate released by damaged plant cells plays a role in activating the CNGC13-mediated signalling pathway.
4. The activation of this pathway inhibits the production of defence-related phytohormones such as Jasmonic Acid.

Which of the statements given above are correct?

3. With reference to Jupiter's bow shock and plasma wave activity, consider the following statements:

1. Jupiter's bow shock is formed due to the interaction between the solar wind and Jupiter's magnetosphere.
2. Intermediate shocklets and layered transition regions help decelerate the incoming solar wind at Jupiter's bow shock.
3. The Juno spacecraft has observed strong harmonic plasma wave structures and intense particle heating across Jupiter's bow shock.
4. Jupiter's bow shock does not undergo periodic self-reformation under intense solar wind pressure.

Which of the statements given above are correct?

3. With reference to Overseas Citizen of India (OCI) cardholders and their rights in India, consider the following statements:

4. With reference to NASA's Neil Gehrels Swift Observatory, consider the following statements:

1. It was launched in 2004 primarily to study gamma-ray bursts and other high-energy astronomical phenomena.
2. Increased solar activity can accelerate the orbital decay of low-Earth orbit satellites by increasing atmospheric drag.
3. The Swift Observatory was successfully shifted to a higher orbit through NASA's robotic rescue mission named Link.
4. The observatory is expected to undergo atmospheric re-entry, during which most of its structure is likely to burn up.

Which of the statements given above are correct?

5. With reference to the recently discovered 4,000-year-old defensive structure at Oued Beht, consider the following statements:

1. The structure was discovered in northwestern Morocco, near the Oued Beht river valley.
2. Radiocarbon dating suggests that its original construction dates back to the second millennium BCE.
3. The discovery represents the oldest known large-scale fortified system in North Africa outside the Nile Valley.
4. Archaeological evidence suggests that the structure was primarily constructed to defend against foreign invasions from ancient Egypt.
