The greater the number of amino acid differences in a protein like hemoglobin, the more closely related two species are.

This is false. The more similarities the the amino acid sequences have, the closer related are the species. Therefore the more differences in the sequence, the more further related the two species are.

Dthe lipid is most likely

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
