Glaciers, groundwater and polar ice are part of the hydrosphere.
Explanation:
The hydrosphere is made up of all the water found on the planet. Thus, the Earth's hydrosphere includes surface waters such as seas, lakes and rivers, but also groundwater, glaciers and water bound to the atmosphere and vegetation. In the hydrosphere, water circulates from one place to another and from one state to another.
The terrestrial hydrosphere reaches as far as the highest layers of the atmosphere where water molecules occur, and is therefore mainly limited to the troposphere. Almost no water is present in the stratosphere, from a height of around 15 km.
Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly.
