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 area of land which supplies a river with water is called its drainage basin or catchment area. The Thames basin is the name of the area surrounding the River Thames. Any rain falling on it ends up in the Thames, which takes it to the sea.
