Question

how do properties of water that result from its polarity and hydrogen bonding affect its biological function?

Answer 1

Answer:

The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).

Answer 2

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Explanation:

• The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
• A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.

• Surface tension forms because of water's cohesive property which results from hydrogen bonding and water's polarity.
• In cohesion, water molecules bond together and require a substantial amount of energy to break thus creating high surface tension.
• The effects on water biological functions are:
• The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances.
• Water's polarity allows it to dissolve other polar substances very easily.
