That each living thing on this earth derives from a single less complex ancestor common to all species

What are the names of the states of Hawaii?
Hawaii is one of the 50 US States. It contains Islands. It contains cities. It contains counties. It does not contain any countries or states.
What statement about Chargaffs rules is carrect?
Observations by Erwin Chargaff that concentrations of the four nucleotide bases differ among species. Within a species, the concentrations of adenine and thymine are always about the same and the concentrations of cytosine and guanine are always about the same. In each species, the amount of adenine equals the amount of thymine. The amount of guanine equals the amount of cytosine.

What did Erwin Chargaff accomplish in his life?
Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. The second of Chargaff's rules is that the composition of DNA varies from one species to another, in particular in the relative amounts of A, G, T, and C bases. Such evidence of molecular diversity, which had been presumed absent from DNA, made DNA a more credible candidate for the genetic material than protein.
