Which is one common property of inorganic substances? They are solid at room temperature. They are poor conductors of electricity. They contain carbon. They burn readily.

They are solid at room temperature.

Explanation:

Inorganic substances are substances that does not have carbon and hydrogen. Most inorganic compounds are metals or alkali metals which make them to be able to conduct electricity.

They are solid at room temperature which make them to be poor conductor of electricity at solid state. In the solid state, the individual particles of a substance are in fixed positions to each other because there is not enough thermal energy to be able to overcome the intermolecular interactions between the particles.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
