The earth is made up of many interacting system which are quite dynamic in nature. The earth is sub divided into four components which are THE ATMOSPHERE, THE HYDROSPHERE, THE BIOSPHERE AND THE GEOSPHERE. These are the separate systems that made up the earth system.
The hydrosphere is make up of all the water components on the earth surface and how the water cycle through nature. The atmosphere refers to the layers of gases that surround the planet earth while the biosphere refers to the living components on the earth surface. All these systems interact together to keep life existing on earth.
The density of the clay plate is 1970 kg m⁻³
the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams
so,V= 30 cm⁻³=3x 10-5 m and M= 59.1grams= 0.0591 kg
Therefore, the density of the plate is: M/V
=>d = 1970 kg m⁻³

A receptor refers to a protein molecule, which attains chemical signals from external of a cell. The receptor proteins are categorized by their location. On the other hand, the structural proteins refer to the fibrous proteins. One of the essential activity of the structural protein is to maintain the configuration of the cell.
In the nerve cells, the receptor proteins pick up signals of pain and structural proteins helps in maintaining the shape and configuration of the nerve cell.

Answer:
Both bacteria and blue algae are prokaryote organisms, meaning that they do not have a differentiated nucleus, and therefore they are more primitive. But blue algae are able to perform photosynthesis and so we can believe that the first forms of life on Earth date even further back than 3 and a half billion years ago.
Explanation:
