This is because these lamps have sodium vapor in them. When the light from the tungsten filament hits the sodium vapour molecules, the sodium emits a yellow glow. This is the electromagnetic spectrum of sodium atoms. This is also why when you burn salt (Sodium Chloride) in a flame it burns with a yellow glow. Streetlight is made of sodium vapour becaue they use less electricity hence conserve energy.
Answer:
<u><em>The enzyme 's active site binds to the substrate. When an enzyme binds its substrate it forms an enzyme-substrate complex. Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur</em></u>

<span>The body maintains homeostasis by utilizing homeostatic control systems composed of three parts. the first part, the ___RECEPTOR_ , is the body structure that detects changes in a variable that is either the substance or process that is regulated. these usually consist of ___SENSORY NERVES__ . the change in the variable is the ___STIMULUS__ . The second component is the __CONTROL CENTER__ . It is the structure that interprets input from the receptor and initiates changes through the __EFFECTOR_ (the final component). this final component is the structure that brings about the change to alter the __STIMULUS_ .</span>
Yes, they are.
Minerals are the result of rock metamorphic cycles and other volcanic activities that result to these mixture of different minerals. Minerals can also be the cause of some biogeochemical cycles that occurs on the earth's different spheres.
