Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...

Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

The yeast proteins Sro7 and Sro77, and their metazoan relatives Lgl and tomosyn, interact with plasma membrane SNARE proteins and control cell polarity. Recently, the crystal structure of yeast ...

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...
