Edwin Hubble used the Doppler effect to determine that the universe is expanding. After years of scientific research and observation of different celestial bodies through a telescope, Hubble found that the light from distant galaxies was shifted towards the red end of the spectrum. This red shift indicates that stars are moving away from us and from each other. This phenomenon is called the 'expansion of the universe', also known as the big band theory.
There are four groups of macromolecules. Carbohydrate, Protein, Nucleic acid, and Lipids. Each macromolecule is essential for the growth and formation of cells. Carbohydrates are used for energy and help build the structure of the cell wall. Proteins help build and regulate muscle and tissue. Nucleic acid transfers
and stores information. Lastly Lipids insulate your body and help produce hormones.
