The answer is salt water.
Salt water can conduct electricity or we can say that an electric current is conducted by salt water as salt water is a good conductor of electricity when salt that is sodium chloride or NaCl is dissolved in water , positively charged sodium (Na⁺) and negatively charged chlorine(Cl⁻) molecules are set apart by the water molecule so that they can float easily and freely. We can define the conductivity of a substance as the mobility or movement of ions. So as in water, sodium and chlorine are set apart and can move freely so it become a electrolyte that can conduct electricity.
If the Suns heat is being reflected, then it is making the Earth cooler.
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
Answer:

The reactant that is reduced is 
Explanation:
The complete equation is as below:

<em>Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.</em>
In the above reaction,
loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to
, hence the reducing agent.
<u>In order words, </u>
<u> is reduced while coenzyme Q is oxidized.</u>
