Sean is trying to decide if a cell is a plant or animal cell. he studies the cell and is able to determine the function of many of the structures in it. which notable structure can him identify the cell?

Coordinates biofilm formation via chemical signaling among cells. (Ans B)

Explanation:

Quorum sensing in bacteria uses to regulate certain expressions such as phenotype which in turn, coordinate their behavior. Some common phenotype examples are biofilm formation, motility, and virulence factor expression.

Some bacteria have the ability to use quorum sensing to regulate nitrogen fixation, bioluminescence, and sporulation. Quorum sensing regulates genes involved in biofilm development, it helps to promote biofilm dispersion and upregulates the synthesis of surfactant molecules. Quorum sensing and biofilm development are known as social bacterial behaviors.
