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.

Answer:
Proteinuria occurs when the filtration membrane becomes leaky, allowing proteins to cross. This impacts the blood colloid osmotic pressure by decreasing the osmolarity gradient between the blood and filtrate, thereby reducing the strength of this pressure.
Explanation:
Proteinuria is the medical term that describes the presence of proteins in the urine. <u>Proteins, in normal conditions, are not capable of filtrating through the membrane</u> but, in the presence of a disease, this is possible. 
Proteins are responsible for the colloid osmotic pressure in the blood vessels, so when proteins get filtered, this pressure decreases and so does the osmolarity gradient between the blood and filtrate. <u>The decrease in osmolarity gradient also produces a decrease of the colloid osmotic pressure because the strength of the pressure is as big as the gradient between the two compartments</u>.
