RPSC - RAS
This subtopic covers diverse scientific concepts including biodiversity, biotechnology, environmental science, and technology. It is crucial for the RPSC exam as it tests foundational knowledge and application in various scientific domains.
Key Concepts
Biodiversity Threats
Human activities, pollution, and habitat destruction reduce biodiversity.
Bio-fertilizers
Organic substances that enhance soil fertility and plant growth.
Greenhouse Gases
Gases contributing to the greenhouse effect and global warming.
Nanoparticles
Particles with at least one dimension less than 10^-7 meters.
Carbon Footprint
Total greenhouse gas emissions from human activities.
Quantum Dots
Semiconductor nanostructures with unique optical properties.
IoT Layers
Perception layer enables wireless communication in IoT devices.
Micro-minerals
Essential minerals required in small quantities in the body.
Trisomy 21
Genetic disorder caused by presence of an extra chromosome 21.
Non-renewable Resources
Resources that cannot be replenished within a human timescale.
