A bаcteriаl cell sitting оut оn аn оutdoor surface in the bright sunshine loses its ability to manufacture functional adhesin proteins that allow it to attach to the inside lining of the human pharynx. It still manufactures the adhesin proteins, but their amino acid sequences have been altered and are no longer functional. Explain what you think happened (consider that sunlight includes ultraviolet light) and how the functional adhesin proteins changed to become non-functional. Is this an example of natural selection? Why or why not? View the scoring rubric for this question, and be sure to include all details.
