Why is it easier to have degradation of petroleum hydrocarbons that inorganic compounds like uranium or lead after an accident spill? A) Microorganisms have naturally evolved mechanisms to reduce the hydrocarbons B) Petroleum is an organic compound, so all microorganisms have methods to oxidize it C) Microorganinsms have been engineered in the lab to oxidixe the hydrocarbons D) Microorganisms have naturally evolved mechanisms oxidize these hydrocarbons Solution D) Microorganisms have naturally evolved mechanisms oxidize these hydrocarbons Since petrol and petroleum producta are organic, several microorganisms have a natural mechanisms to oxidize them into simple compounds..
