The two basic factors which are most important in determining the current appearance of a star are its mass and its stage of life. Stars are born with 75% Hydrogen and 25% Helium, with no more than 3% of that being heavier elements. A star burns its supply of elements over its lifetime, the larger the mass of the star then the greater it's brightness, luminosity and surface temperature will be. Dependant on the stage of the star's life, the color of the light will change.

Since the body is mainly composed of water solutions, molecules in the body need to be hydrophilic to interact positively with the water. For proteins to dissolve well in the body the hydrophilic groups are located on the outside of the folded proteins while the hydrophobic groups are ‘hidden’ in the inside of the protein. If the hydrophobic parts were located in the outside, the proteins would clump up togetehr and interfere with their functions.
