The hydrogen bonds in a water molecule make water a good ____.

A Surface for small particles and living organisms to move across

The hydrogen bonds between water molecules cause water molecules to attract each other (negative pole to positive pole. and “stick” together. This gives water a high surface tension, which allows small living organisms, such as water striders, to move across its surface. Since water is a polar molecule, it readily dissolves other polar and ionic molecules such as carbohydrates and amino acids. Polarity alone is not sufficient to make something soluble in water, however; for example, cellulose is polar but its molecular weight is so large that it is not soluble in water.
