Doubly ionized lithium li2+ (z = 3) and triply ionized beryllium be3+ (z = 4) each emit a line spectrum. for a certain series of lines in the lithium spectrum, the shortest wavelength is 253.5 nm. for the same series of lines in the beryllium spectrum, what is the shortest wavelength?

Domain eukarya; kingdom plantae should be the answer.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

When is this
