Answer:
Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometres.) Astronomers also measure luminosity — the amount of energy (light) that a star emits from its surface.

If we do not take in a certain amount of amino acids, we would not be able to make some proteins that are needed for the body. It would not mean all proteins wouldn’t be made, but if you are missing one essential amino acid it would lead to one type of protein not being made

Diffusion is movement of particles from an area of high concentration to an area of low concentration. Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a solution with a high solute concentration, down a solute concentration gradient.
