Hubble's Law is the recessional velocity, which is the speed of a celestial body moving away from the observer, is proportional to its distance.
It states The Universe is expanding, our galaxy is expanding, red shift is proportional to a body's distance from us, and red shift is proportional to distance form the center of the universe.
Answer:
facilitated diffusion
Explanation:
In facilitated diffusion, certain transport proteins of membranes (channels and carriers) serve in transport of the substances across the membrane. The movement of the amino acid occurs down the concentration gradient only. In facilitated diffusion, transport of substances occurs from the region of their higher concentration to that of the lower concentration. It is a passive process. The addition of some other amino acid slows down the transport of the first amino acid due to the saturation effect. All the transport proteins that facilitate the diffusion of amino acids across the membrane become occupied. This slows down the transport of the amino acid.
