Question 36

Water helps keep temperature stable.

Water plays a crucial role in regulating the temperature of living organisms, primarily by absorbing and releasing heat slowly. This property of water allows it to maintain a stable internal environment, which is vital for the proper functioning of biological processes.

A) Water increases temperature.

This option is incorrect because while water can absorb heat, it does not inherently increase the temperature of living organisms. Instead, its high specific heat capacity allows for temperature moderation rather than elevation.

B) Water helps keep temperature stable.

This option is correct as water's ability to absorb and retain heat helps to buffer temperature changes in living organisms. This stabilization is essential for maintaining homeostasis, enabling biochemical reactions to occur efficiently.

C) Water decreases temperature.

This statement is misleading. While water can absorb heat and cause a cooling effect in certain contexts, such as sweating in humans, it does not inherently decrease the temperature of living organisms. Instead, it serves to regulate and stabilize temperatures.

D) Water does not affect temperature.

This option is incorrect because water significantly impacts temperature regulation in living things. Without water's thermal properties, organisms would struggle to maintain their internal temperatures, leading to potential physiological stress.

Conclusion

The correct answer, "Water helps keep temperature stable," highlights water's essential role in thermoregulation within living organisms. Other options either misrepresent the influence of water on temperature or overlook its critical function in maintaining a stable internal environment, which is vital for life processes.
