What are the key applications and benefits of biotechnology in environmental science, agriculture, and medicine?

Here are the answers to your questions:

15. b) Detecting pollutants through genetic responses. Explanation: Molecular markers can identify specific genetic changes or expressions in bioindicator organisms that signal the presence of pollutants or environmental stress, providing a sensitive way to monitor environmental health.

16. b) Are based on living organisms or natural compounds. Explanation: Biofertilizers use beneficial microorganisms to improve soil fertility, and biopesticides use natural substances or living organisms to control pests, distinguishing them from synthetic chemical products.

17. b) Are cheaper, safer alternatives to existing biologic drugs. Explanation: Biosimilars offer a more affordable option to expensive original biologic drugs, increasing patient access to critical treatments, while demonstrating comparable safety and efficacy.

18. c) Production of biofuels from renewable biomass. Explanation: Producing biofuels from renewable biomass directly contributes to climate change mitigation by reducing reliance on fossil fuels and lowering greenhouse gas emissions.

19. b) Transparent science communication and biosafety oversight. Explanation: Openly communicating the science behind GMOs, along with robust regulatory oversight and safety assessments, helps build public trust and address skepticism.

20. c) Integration of AI, genomics, and global cooperation. Explanation: The future of biotechnology will heavily depend on leveraging artificial intelligence for data analysis, genomics for understanding biological systems, and global collaboration for shared knowledge and resources to drive innovation.
