Answer:

How long ago did two species of birds share an ancestor?

Explanation:

Molecular clocks estimates the time of divergence of two species or populations from each other. The process compares the total number of different nucleotide present in genome of two organisms. The average rate at which the specific gene evolves tells about the dates of evolutionary branch points. By comparing the total number of different nucleotides present in genome of two birds species, molecular clock can answer "How long ago did two species of birds share an ancestor?"

slavikrds [6]

The ribosomal RNA studies that led to the division of prokaryotic organisms into the bacteria and the archaea were begun by Woese.

Ribosomal RNA makes the maximum portion of RNA in the cells. However, it is not translated into proteins. But it plays a major role in the translation of m-RNA. They are responsible for deducing the order of the amino acid sequence and linking the amino acids together to form the polypeptide.

Archaea are a group of organisms that are similar to bacteria, yet have evolutionary differences. They are found in extreme locations like hot spring, salty water bodies, or areas where methane if formed. Therefore, they are also known as extremophiles.

Can molecules made from the same atom form ionic bonds. Why?
Digiron [165]
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
