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).
Sandy produced long-duration, record high waves on lower Lake Michigan earlier this week. According to the National Weather Service, the highest recorded wave height on the south mid-lake Michigan buoy during Sandy was 21.7 feet, at 11:50 a.m. CDT, Tues., Oct. 30. This is the second-highest wave height on record, which spans approximately 31 years. The record of 22.9 feet on Sept. 30, 2011 still stands.
