What is the difference between inorganic and organic compounds?

The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms. ... Meanwhile, inorganic compounds include the salts, metals, and other elemental compounds.

Carbon backbone is present in organic molecules. Inorganic molecules do not have carbon.

Explanation:

The main difference between inorganic and organic compound is the presence of a carbon backbone in the organic molecules. While, inorganic compounds do not have it, this means it lacks a carbon atom (except CO2, which is considered inorganic)

Carbon has the ability to form large and complex molecules and bond to itself many times, and it can be bonded to hydrogen and also other atoms.

For example, living organisms are made of organic molecules because they form DNA, lipids, proteins and carbohydrates. Meanwhile, examples of inorganic compounds include metals, salts and others.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
