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 Thames flows through Oxford, Reading, Windsor and London. It ends in the Thames estuary. It used to be heavily polluted. In 1858, the 'Great Stink' caused sittings of Parliament (which is next to the river) to be abandoned, which caused the Victorian London sewerage system to be built.
