The term "Nikkomycin," recently seen in the news, is associated with: A new vaccine developed to prevent viral infections in humans. A herbicide developed to control weed growth in agricultural fields. A chitin synthesis inhibitor used in developing antifungal treatments. A protein supplement aimed at improving muscle growth in athletes. Explanation:Relevance: A team of scientists have used a chitin synthesis fungicide, Nikkomycin, produced by the bacterial Streptomyces spp. to develop Nikkomycin loaded polymeric nanoparticles.Nikkomycin is a chitin synthesis inhibitor produced by Streptomyces bacteria. Scientists have used Nikkomycin to develop a nanoparticle-based delivery system targeting fungal infections. Since chitin is a key component of fungal cell walls and is absent in the human body, this makes it an ideal target for antifungal drugs. The nanoparticle delivery system helps disrupt fungal growth by targeting the chitin in the fungal cell walls.Therefore, option (c) is the correct answer.Subject: Current Affairs | S&TLevel of Difficulty: Easy | Factual 2 / 5 Q2. With reference to different generations of biofuels, consider the following statements:1) First-generation biofuels are produced from non-food crops like algae and cyanobacteria.2) Second-generation biofuels are derived from high-value food crops like corn and sugarcane.3) Third-generation biofuels are obtained from algae and cyanobacteria.4) Fourth-generation biofuels are produced from combining genetically modified crops.How many of the above statements are correct? Only one Only two Only three All four Explanation:Relevance: The Government is promoting 2nd-generation (2G) Ethanol, which is derived from surplus biomass, agricultural waste, and industrial waste using advanced biofuel technology.Biofuel is any fuel that is derived from biomass—that is, plant or algae or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas. First-generation biofuel: They are produced from food crops. (Hence, statement 1 is not correct)Second-generation biofuel: They are derived from low-value biomass that possesses a high cellulose content, including wood chips, crop residues, rice & wheat straw/corn cobs & Stover/bagasse, woody biomass, municipal waste etc. (Hence, statement 2 is not correct)Third-generation biofuel: They are obtained by the use of algae and cyanobacteria. Some estimates state that algae and cyanobacteria could yield between 10 and 100 times more fuel per unit area than second-generation biofuels. (Hence, statement 3 is correct)Fourth-generation biofuel: Fourth-generation technology combines genetically optimized feedstocks, which are designed to capture large amounts of carbon, with genomically synthesized microbes, which are made to efficiently make fuels. (Hence, statement 4 is correct)Key to the process is the capture and sequestration of CO2, a process that renders fourth-generation biofuels a carbon negative source of fuel. Plant-based biofuels in principle make little net contribution to global warming and climate change; the carbon dioxide (a major greenhouse gas) that enters the air during combustion will have been removed from the air earlier as growing plants engage in photosynthesis. Such a material is said to be “carbon neutral.” So, only two of the statements given above are correct.Therefore, option (b) is the correct answer.Subject: Current Affairs | EnvironmentLevel of Difficulty: Medium | Factual 3 / 5 Q3. With reference to the land features as defined by the United Nations Convention on the Law of the Sea (UNCLOS), consider the following statements:1) An island must be able to sustain human habitation or economic life and is entitled to a 200 nautical mile exclusive economic zone (EEZ).2) Rocks, which cannot support life, can claim a 200 nautical mile exclusive economic zone but not territorial waters.3) Low tide elevations, which are above water at low tide but submerged at high tide, cannot claim an exclusive economic zone (EEZ) or territorial waters.Which of the statements given above are correct? 1 and 3 only 1 and 2 only 2 and 3 only 1, 2, and 3 Explanation:Relevance: China's bullying tactics in the South China Sea are endangering regional stability and harming the livelihoods of Filipino fishermen.According to the United Nations Convention on the Law of the Sea (UNCLOS), an island must be able to sustain human habitation or economic life to be entitled to a 200 nautical mile exclusive economic zone (EEZ). (Hence, statement 1 is correct)Rocks, which cannot support life, are entitled to only 12 nautical miles of surrounding territorial waters, not a 200 nautical mile EEZ. (Hence, statement 2 is not correct)Low tide elevations are naturally formed areas that are above water at low tide but submerged at high tide. These features cannot claim either an EEZ or territorial waters, according to UNCLOS, because they do not meet the criteria for generating such maritime zones. (Hence, statement 3 is correct)Therefore, option (a) is the correct answer.Subject: Current Affairs | IRLevel of Difficulty: Medium | Factual 4 / 5 Q4. The "waggle dance" is a behavior associated with which of the following species? Ants, as a form of communication to find food sources. Butterflies, as a mating ritual to attract potential partners. Honeybees, to communicate the direction and distance of food sources to other members of the colony. Termites, to coordinate the construction of their mounds. Explanation:Relevance: Honeybees use dance moves for directions to efficiently guide their colony members to the most rewarding food sources.The "waggle dance" is a unique behavior exhibited by honeybees. This dance is performed by forager bees to inform other members of the hive about the direction and distance of food sources relative to the sun. The dance involves a figure-eight pattern, and the angle and duration of the waggle part of the dance communicate precise information about where the food source is located. This sophisticated form of communication is crucial for the efficiency of the hive in gathering resources.Therefore, option (c) is the correct answer.Subject: Current Affairs | S&TLevel of Difficulty: Easy | Factual 5 / 5 Q5. With reference to international relations, the term "Global South" refers to: The group of economically developed countries primarily located in the southern hemisphere. Nations that are part of the European Union and situated in the southern part of Europe. Countries that are economically disadvantaged and primarily located in Africa, Latin America, and Asia. The collective of countries that are members of the Southern Hemisphere Climate Pact. Explanation:Relevance: The third Voice of Global South Summit was recently hosted by India in the virtual format.The term "Global South" is used in international relations to refer to countries that are generally economically disadvantaged or developing, primarily located in Africa, Latin America, and Asia. This term contrasts with the "Global North," which typically includes wealthier, industrialized nations like those in North America and Europe. The Global South encompasses a wide range of countries that often face challenges such as poverty, underdevelopment, and inequality.Therefore, option (c) is the correct answer.Subject: Current Affairs | IRLevel of Difficulty: Easy | Factual Your score is 0% Restart quiz
