• A. analysis of planetary motion
• B. study of the physical structure of atoms
• C. measurement of atmospheric pressure
• D. manipulation of living organisms or their components to produce useful products

Answer: (D)

Verified step by step guidance

1. Understand the definition of biotechnology: Biotechnology is a field of biology that involves the use of living organisms, cells, or biological systems to develop products or technologies that benefit humans.
2. Eliminate incorrect options: Analyze the given choices and identify which ones are unrelated to biotechnology. For example, planetary motion, the physical structure of atoms, and atmospheric pressure are topics from physics or astronomy, not biology.
3. Focus on the correct concept: Recognize that biotechnology specifically deals with manipulating living organisms or their components, such as DNA, enzymes, or cells, to create useful products like medicines, biofuels, or genetically modified crops.
4. Relate to real-world examples: Consider examples of biotechnology applications, such as genetic engineering, fermentation processes, or the development of vaccines, to reinforce understanding of the concept.
5. Conclude with the correct answer: Based on the analysis, the correct answer is 'manipulation of living organisms or their components to produce useful products,' as this aligns with the definition and applications of biotechnology.
