Verified step by step guidance

1. Step 1: Begin by understanding the scope of biology as a scientific discipline. Biology is the study of life and living organisms, including their structure, function, growth, evolution, distribution, and interactions with their environment.
2. Step 2: Eliminate options that do not align with the focus of biology. For example, 'The analysis of chemical reactions in non-living matter' pertains to chemistry, not biology.
3. Step 3: Similarly, 'The exploration of celestial bodies and their movements' is the focus of astronomy, not biology.
4. Step 4: 'The study of economic systems and resource allocation' is related to economics, which is outside the scope of biology.
5. Step 5: Conclude that the correct description of biology is 'The study of living organisms and their interactions with the environment,' as this encompasses the primary focus of the discipline.
