Some ground-dwelling, toxin-loving organisms actually “breathe” the organohalide molecules in, separating some or all of the halogen molecules in the process, the same way humans inhale oxygen and.
Chemical properties Carbon does not dissolve in or react with water, acids, or most other materials. It does, however, react with oxygen. It burns in air to produce carbon dioxide (CO 2 ) and carbon monoxide (CO).The combustion (burning) of coal gave rise to the Industrial Revolution (1700-1900).

DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms.This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes.DNA is inherited by children from their parents. This is why children share traits with their parents, such as skin, hair.
