What is the greenhouse effect, and how does human activity contribute to it?
Answer: The greenhouse effect is a natural process where atmospheric gases trap heat; human activity enhances it by increasing greenhouse gas concentrations through burning fossil fuels
The greenhouse effect is natural, but human activities — particularly burning fossil fuels — release extra CO₂ and methane, intensifying warming beyond natural levels.
What is CRISPR technology primarily used for in science?
Answer: Editing or modifying genes in living organisms with high precision
CRISPR-Cas9 is a gene-editing tool that allows scientists to precisely modify DNA sequences in living organisms.
How does social media affect the spread of information in modern society?
Answer: Social media enables rapid, widespread sharing of information, but also accelerates the spread of misinformation and disinformation
Social media is a powerful information distribution tool, but its algorithms can amplify false or misleading content as rapidly as factual information.
What is the primary goal of renewable energy technology development?
Answer: To replace fossil fuels with energy sources that are sustainable and produce fewer greenhouse gas emissions
Renewable energy technologies aim to meet energy needs using sustainable sources — like solar, wind, and hydro — while reducing greenhouse gas emissions.
What ethical concern is most commonly associated with artificial intelligence (AI) in the workplace?
Answer: AI displacing human workers from jobs, raising questions about economic inequality and the future of work
A major ethical concern about AI is automation-driven job displacement, which could increase economic inequality and require major social adjustments.
What is biodiversity, and why is it important?
Answer: Biodiversity is the variety of life on Earth — including genes, species, and ecosystems — and is crucial for ecosystem stability, food security, and medicine
Biodiversity encompasses all living organisms and their interactions; it underpins ecosystem health, agricultural resilience, medical discovery, and clean air and water.
