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.
(Because of its low atomic weight, even though 63% of the atoms in a body are Hydrogren, this equates to just 10% of the mass of a body). 99% of the mass of the human body is made up of the six elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus.Because of its low atomic weight, even though 63% of the atoms in a body are Hydrogren, this equates to just 10% of the mass of a body). 99% of the mass of the human body is made up of the six elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus.
