<span>This finding that all known organisms use genetic information to produce protein molecules via the same genetic code strongly supports the hypothesis that all organisms are descended from a single common ancestor.
Genetic information is the biological information coded in the dna or rna sequences, like chromosomes.
A specie from which two different species are evolved is a common ancestor.</span>

The cell wall, capsule, pilus, and flagella are the bacterial structure that is located on the surface of a bacterial cell.
Cell wall: It is composed of a protein-sugar(polysaccharide) molecule which gives the cell its shape, and rigidity and protects it from the environment.
Capsule: It is a third protective covering that is made up of polysaccharides. It plays many roles but the important ones are to keep the bacterium from drying out and to protect it from engulfing by larger microorganisms.
Pilus: These are specifically small hairlike projections that emerges from the outside of the cell surface. It helps bacteria to attach to the host organism.
Flagella: (singular, flagellum) a hairlike structure that provides a means of location for bacteria. These are mainly found at either or ends of all over its surface.

Living things are placed into certain kingdoms based on how they obtain their food, the types of cells that make up their body, and the number of cells they contain. The phylum is the next level following kingdom in the classification of living things.
Answer:
C) All DNA has the same structure, so the modeled DNA could be found in any living organism.
Explanation:
The DNA is the abbreviation for deoxyribonucleic acid. all the living organisms have DNA as their hereditary material. The DNA is consist of nucleotides. The nucleotide are the combination of deoxyribose sugar, nitrogenous base and phosphate ion. The nucleotide unit is same in the DNA of all the organism including bacteria. The bases adenine, cytosine, guanine and thymine is present in all type of organism. The sequential arrangement of the bases determine the character of the organism.
