I've seen the same planet colored differently in different photos. Here are the true colors of the planets, with links to some relevant images from NASA spacecraft. (Note that spacecraft photos appearing in the media often have false coloration.) Mercury: gray (or slightly brownish). Mercury has practically no atmosphere, so we just see the rocky surface.
The composition of the human body is expressed in terms of chemicals: 1  Water. 2  Proteins â including those of hair, connective tissue, etc. 3  Fats (or lipids) 4  Hydroxylapatite in bones. 5  Carbohydrates such as glycogen and glucose. 6  DNA. 7  Dissolved inorganic ions such as sodium, potassium, chloride, bicarbonate, phosphate.
Human body consists of Inorganic and Organic compounds. The human body is made up of atoms, ions and molecules. Life processes depend on the organization and interaction of these chemical units. An atom is the smallest amount of the chemical element that has the characteristic properties of that element.An ion is an electrically charged atom or a group of atoms.he human body is made up of atoms, ions and molecules.
