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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
