With reference to the protein p47, recently in news, consider the following statements:
- p47 functions only as a cofactor of p97, assisting in protein degradation.
- Recent research has shown that p47 acts as a mechanical chaperone, stabilising proteins under force.
- p47 enhances the efficiency of extracting proteins from the endoplasmic reticulum (ER) lumen into the cytoplasm.
Which of the above statements is/are correct?

Which of the above statements is/are correct?
2.
Assertion (A): Proteins inside cells often unfold or misfold due to mechanical stress. Reason (R): Cellular mechanical forces arise during processes like transport, degradation, and cytoskeletal changes.
3.
With reference to the Wangchhu Hydroelectric Project, consider the following statements:
- It is located in Bhutan’s Chukha District on the Wangchhu River, a tributary of the Brahmaputra.
- The project is being developed jointly by Adani Power and Bhutan’s Druk Green Power Corporation (DGPC).
- It is based on the Build, Own, Operate, Transfer (BOOT) model.

With reference to India’s first port-based green hydrogen project, consider the following statements:
- It is located at V.O. Chidambaranar (VOC) Port in Tamil Nadu.
- The pilot facility produces 10 Nm³ per hour of green hydrogen.
- The hydrogen generated is used to power streetlights and an EV charging station inside the port colony.
- The project was established at a cost of ₹35.34 crore.
Which of the above statements is/are correct?
6.
Assertion (A): The Green Methanol Bunkering Facility at VOC Port will strengthen South India’s role in sustainable shipping. Reason (R): The facility will have a capacity of 750 m³ and will be the first methanol production unit in India.
7.
With reference to Bhubaneswar’s Integrated Heat and Cooling Action Plan (IHCAP), consider the following statements:
- Bhubaneswar is the first Indian city to launch such a plan.
- The plan unifies India’s Cooling Action Plan and Heat Action Plan.
- Urban growth between 2018–2024 led to a 10% loss in vegetation and a 75% loss in water bodies.
- Household air-conditioning usage increased from 6% in 2021 to 25% in 2023.
Which of the above statements are correct?
8.
Assertion (A): The urban heat island effect makes Bhubaneswar hotter than the surrounding rural areas. Reason (R): Rapid urbanisation reduced vegetation and water bodies, increasing heat retention.
9.
With reference to the Emerging Science, Technology and Innovation Conclave (ESTIC), consider the following statements:
- It is being organised by the Department of Science and Technology (DST) in November 2025.
- The conclave will be held at Bharat Mandapam in New Delhi.
