<em><u>Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).</u></em>
Answer: This was curious, because during so-called REM sleep (rapid eye movement), our muscles are usually paralysed. Researchers realised that inducing a similar state in animals could allow them to probe how they dream.
<em><u>Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. </u></em>
