The atomic number of hydrogen is 1 (count the protons). The atomic mass number of hydrogen is also one (there are no neutrons!). For carbon, the atomic number is 6, and the atomic mass number is 12 (6 protons plus 6 neutrons). Adding the two neutrons changes our atom.
Crude oil is usually found below natural gas reservoirs, so the answer is C. Keep in mind, however, that this is not always the case, and that crude oil can be found above gas as well.

Enzymes catalyze specific reactions.
Explanation:
Enzymes are known as both biological catalysts and proteins. It is a substance that acts as a biological catalyst in an organism. The biological processes are chemical reactions, most are regulated by the help of enzymes that occur within all living organisms.
Enzymes are the highly selective catalyst in nature means each enzyme only helps to speed up a specific reaction. Catalysts help to lower the activation energy for reactions. So, if lower the activation energy for a reaction, the faster the rate of reaction.
