Daily Current Affairs MCQ- December 11, 2023 - UPSC MCQ

Recently, researchers from the Indian Institute of Science’s (IISc.) molecular biophysics unit in a study have identified that peptides (short protein) produced from Budgett’s frog can combat enzymes of disease causing pathogens.

• Budgett’s frogs are highly intelligent and very aggressive.
• When frightened, they inflate themselves, stand up on their short legs and if this doesn’t deter the potential predator, they lunge at them with an open huge mouth followed up by a shrill shriek.
• During the dry season, Budgett’s frogs remain in burrows they dig in the bottoms of pools of water.
• While in the burrow, they will shed several layers of skin from which to form a waterproof cocoon that will keep the frog moist.
• They use their exceptional night vision and their sensitivity to movement when hunting food.
• Habitat/range: They are found near or in permanent or seasonal bodies of water in Paraguay, Argentina and Bolivia.
• Conservation Status

IUCN Red List: Least Concern

Hence both statements are correct.

Recently, the Ministry of Electronics and IT has said that the program- 'YUVAi- Youth for Unnati and Vikas with AI’ will be featured at the Global Partnership on Artificial Intelligence (GPAI) Summit.

• This programme, designed to equip the youth with essential Artificial Intelligence skills, has garnered attention for its innovative approach and commitment to enabling a future-ready workforce.
• It is aimed to foster a deeper understanding of AI, to enable school students from class 8 to 12 across the nation with AI skills and empower them to become human-centric designers and users of AI.
• Key Updates and Features of YUVAi Programme:
• Progressing in three phases, the YUVAi programme is being implemented in multiple cohorts to ensure that maximum students stand a chance to become future-ready. It introduces students to several social themes to direct their AI knowledge towards solving real-world problems.
• In the first Cohort, more than 8,500 students registered, post which, they attended online orientation sessions to learn fundamental concepts of AI. Teachers also enrolled into the program and underwent orientation sessions. Students then submitted innovative AI-based ideas under one of the eight core themes of the programme.
• In phase 2, Top 200 AI-based ideas were shortlisted. Shortlisted students attended online deep dive AI training and mentorship sessions with certified Intel AI coaches and experts – helping students enhance their solutions. Students then submitted their AI projects to be evaluated for Phase 3.
• In Phase 3, top 50 students were shortlisted and they were invited to attend a four-day face-to-face rapid modeling workshop – receiving one-on-one mentorship, apprenticeship and guidance from industry experts to fine-tune their projects and develop them into prototypes.
• An on-spot project presentation was conducted by a multiple jury panel to shortlist Top 10 students.

Hence only statement 2 is correct.

Recently, marine biologists said that a huge clam that was on the verge of extinction has made a comeback, with a surge in numbers in waters off Croatia.

• Pinna nobilis is a large species of Mediterranean clam, a marine bivalve mollusca in the family Pinnidae.
• The clams, whose shells can grow as much as 1.2 m across, play an important ecological role by filtering sea water and allowing other organisms to flourish.
• It attaches itself to rocks using a strong byssus composed of many silk-like threads which used to be made into cloth.
• The animal secretes these fibres from its byssus gland; they consist of keratin and other proteins and may be as long as 6 cm (2.4 in). The inside of the shell is lined with brilliant mother-of-pearl.
• As with other members of its genus, Pinna nobilis hosts symbiotic shrimp which live inside its shell.
• It is believed that when it sees a threat, the shrimp warns the host, perhaps by retracting its claws or even by pinching. The clam then closes shut.
• It has been demonstrated that the shrimp has a similar filter-feeding diet to its host and the relationship is likely mutualistic.
• Distribution: This species is endemic to the Mediterranean Sea. 
• Threats: It is relatively fragile to pollution and shell damage.
• The clam, known as the noble pen shell or pinna nobilis, started dying out as a deadly pathogen spread in parts of the Mediterranean around 2016.
• Conservation status
• IUCN: Critically endangered

Hence option (a) is the correct answer.

• The climate protection performance is assessed in four categories: GHG Emissions, Renewable Energy, Energy Use and Climate Policy.

Hence option (b) is the correct answer.
