Question

Mark the following statements as true or false concerning waters relevance to living systems. Water is the universal solvent in biological systems. Water bathes organs in fluid, which provides protection and support. The high specific heat of water means that we only lose a small amount of heat when the sweat on our skin evaporates. Water plays a major role in our bodies’ chemical reactions.

Answer 1

Water is the universal solvent in biological systems and plays a major role in our bodies' chemical reactions. It also bathes organs in fluid, providing protection and support. The high specific heat of water helps regulate body temperature.

Step-by-step explanation:

Water is the universal solvent in biological systems, meaning it can dissolve many substances necessary for life. Water also bathes organs in fluid, providing protection and support. Additionally, the high specific heat of water allows us to lose a small amount of heat when sweat on our skin evaporates, helping to regulate body temperature. Lastly, water plays a major role in our bodies' chemical reactions, as many biochemical processes occur in the watery contents of cells.

Answer 2

Water is the universal solvent in biological systems. - TRUE

Water bathes organs in fluid, which provides protection and support. - FALSE

The high specific heat of water means that we only lose a small amount of heat when the sweat on our skin evaporates. - FALSE

Water plays a major role in our bodies’ chemical reactions. - TRUE

Step-by-step explanation:

Water dissolves polar molecules hence critical solvent for energy molecules such as glucose and electrolytes such as sodium. Water also acts as a metabolite in reactions such as photolysis in photosynthesis and also in hydrolysis reactions. Water is a temperature buffer due to its high heat capacity (meaning it takes more energy to raise the temperature of water by one degree). This means it is good for the regulation of temperatures in the body.
