3. which of the following is the most accurate distinction between organic molecules and inorganic molecules? organic molecules are composed primarily of carbon atoms bound to other atoms and most inorganic molecules are not. organic molecules contain carbon and inorganic molecules do not contain carbon. organic molecules are synthesized by living things and inorganic molecules are not. organic molecules are consumed by living things and inorganic molecules are not.

Organic molecules are composed primarily of carbon atoms bound to other atoms and most inorganic molecules are not.

Explanation:

Organic means that a molecule has a carbon backbone with some hydrogen thrown in for good measure. Living creatures are made of various kinds of organic compounds.

Inorganic molecules are composed of other elements. They can contain hydrogen or carbon, but if they have both, they are organic.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
