in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes.he size of the nucleolus is a function chiefly of the cellâs ribosome requirement; the nucleolus is, therefore, especially large in a cell that intensively synthesizes proteins. Protein synthesis, the end result of chromosome function, occurs mainly in the cytoplasm.
In physical oceanography, the significant wave height (SWH or H s) is defined traditionally as the mean wave height (trough to crest) of the highest third of the waves (H 1/3).

The United States Wave Height image shows the expected wave height for coastal areas for the current day. Ocean surface waves are surface waves that occur in the upper layer of the ocean. They usually result from wind or geologic effects and may travel thousands of miles before striking land. They range in size from small ripples to huge tsunamis.
