Which of the following best describes the primary focus of biology as a scientific discipline?

• A. The investigation of physical laws governing motion and energy
• B. The study of living organisms and their interactions with the environment
• C. The exploration of celestial bodies and the universe
• D. The analysis of chemical reactions in non-living matter

Answer: (B)

Verified step by step guidance

1. Understand the scope of biology as a scientific discipline. Biology is the study of living organisms, their structure, function, growth, evolution, and interactions with their environment.
2. Eliminate options that are unrelated to the study of living organisms. For example, the investigation of physical laws governing motion and energy is primarily the focus of physics, not biology.
3. Similarly, the exploration of celestial bodies and the universe falls under astronomy, which is not the focus of biology.
4. The analysis of chemical reactions in non-living matter is a focus of chemistry, not biology. Biology focuses on chemical processes within living organisms.
5. Conclude that the correct answer is: 'The study of living organisms and their interactions with the environment,' as this best describes the primary focus of biology.
