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).
Tsunamis range in size from inches to over a hundred feet. In deep water (greater than 600 feet/180 meters), tsunamis are rarely over 3 feet (1 meter) and will not be noticed by ships due to their long period (time between crests). As tsunamis propagate into shallow water, the wave height can increase by over 10 times.Tsunami heights vary greatly along a coast.
