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).
Contours of the sea floor and coastline have a profound influence on the height of waves. In 1993, Okushiri, Japan, the wave run-up on the coast averaged ~15-20 meters (50-65 feet). In one spot, waves pushed into a V-shaped valley open to the sea, concentrating the water in a tighter and tighter space.eacher Background Wave height-vertical measurement of the wave before it reaches the shore Run-up-vertical height a wave reaches above a reference sea level as it washes ashore.
