Which description best defines biotechnology?

• A. The study of fossils
• B. The production of electricity from microbes
• C. The manipulation of living organisms to create useful products
• D. The analysis of atmospheric gases

Answer: (C)

Biotechnology is about using living organisms or their components to create products and processes that benefit people. The description that best fits captures this practical focus: manipulating living organisms to create useful products. It reflects how biotech applies biology to make things like medicines, agricultural improvements, industrial enzymes, and other tangible outputs.

The other ideas miss that broader, applied aspect. Studying fossils is about ancient life and evolution, not using living systems to produce goods. Analyzing atmospheric gases is environmental/analytical work, not about engineering or applying biology to create products. Producing electricity from microbes is a potential application within biotechnology, but it’s a specific use rather than the defining idea of the field.
