Approximately what percentage of a typical organism's body is composed of water?

• A. 60-70%
• B. 80-90%
• C. 30-40%
• D. 10-20%

Answer: (A)

Verified step by step guidance

1. Understand that water is a major component of living organisms, playing crucial roles in biological processes such as nutrient transport, temperature regulation, and chemical reactions.
2. Recognize that the percentage of water in an organism's body can vary depending on the species and its environment, but there is a typical range for most organisms.
3. Consider the options provided: 60-70%, 80-90%, 30-40%, and 10-20%. Reflect on the fact that water is essential for life and typically constitutes a significant portion of an organism's body.
4. Recall that for most organisms, especially humans and other mammals, the body is composed of a substantial amount of water, often cited in biology textbooks as around 60-70%.
5. Conclude that the typical percentage of water in an organism's body is most likely within the range of 60-70%, based on common biological knowledge and the options provided.
