Ethylene Glycol is an antifreeze is an additive which lowers the freezing point of a water-based liquid and increases its boiling point. 

Cathode ray is a beam of electrons emitted   from   the   cathode   of   a vacuum    tube.    It    is    invisible. Cathode  ray  tubes  are  also  found in     televisions     and     computer monitors.  Since  cathode  ray  is  a beam of electrons and all electrons are  identical,  charge  to  mass  ratio is same for all the gases and does not depend on the nature of gas.

SO2 has a net dipole moment and has a bent shape in its structure as water molecule. Hence it is a polar molecule.

A nitrogenous base is an element that contains nitrogen that have same chemical properties of the base.

An enzyme is a variety of catalyst and is the relation between tham. A catalyst is a chemical that increases the rate of a chemical reaction without itself being changed by the reaction.
