Hydrogen bonds are part of what important molecules in organisms?

Water!

Explanation:

Hydrogen bonds occur due to water molecules being polar (which results from the uneven distribution of their electrons), thus causing come charge to be remaining in the Oxygen and Hydrogens in water molecules. This causes Oxygens and Hydrogens from different water molecules to attract each other as well! Most importantly, however, hydrogen bonds allow water molecules to have its cohesive properties, which allows it to do many of things water is essential for. Hint: capillary action.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
