The gel-like material within the cell membrane is referred to as the cytoplasm. It is a fluid matrix, the cytosol, which consists of 80% to 90% water, salts, organic molecules and many enzymes that catalyze reactions, along with dissolved substances such as proteins and nutrients.
The River Thames is the second longest river in the United Kingdom and the longest river entirely in England, rising at Thames Head in Gloucestershire, and flowing into the North Sea at the Thames Estuary.
The river gives its name to the Thames Valley (Wikipedia page [1]), a region of England centred around the river between Oxford and West London, the Thames Gateway, the area centred around the tidal Thames, and the Thames Estuary to the east of London.
