Multiple Choice

Imagine that organisms consisted of 70–95% alcohol instead of 70–95% water. Alcohol's specific heat is about half that of water. How would living things be different?

Organisms would be able to live in a much wider range of temperatures.

Living organisms would have to be much smaller.

Warm-blooded organisms would require less insulation such as fur or feathers.

Systems for temperature regulation would have to be much more efficient.

Verified step by step guidance

Begin by understanding the concept of specific heat. Specific heat is the amount of heat required to change the temperature of a substance by a certain amount. Water has a high specific heat, meaning it can absorb a lot of heat without a significant change in temperature.

Consider the implications of alcohol having a specific heat that is about half that of water. This means alcohol would heat up and cool down more quickly than water when exposed to temperature changes.

Reflect on how organisms use water's high specific heat to maintain stable internal temperatures despite external temperature fluctuations. This stability is crucial for the proper functioning of biological processes.

Analyze how organisms composed of 70-95% alcohol would respond to temperature changes. With alcohol's lower specific heat, these organisms would experience more rapid temperature changes, requiring more efficient systems to regulate their internal temperature.

Conclude that systems for temperature regulation would have to be much more efficient in organisms composed primarily of alcohol. This is because they would need to quickly adapt to temperature changes to maintain homeostasis and ensure survival.
