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.
The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular components of the body. The adult male body is about 60% water for a total water content of some 42 litres.
