Explanation:
Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
