They are bonded by atoms.
The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.<span>

Answer:
The correct option is (C). The above mentioned definition is true for biofilm that resembles a slimy structure composed of cells attached to each other.
Explanation:
The adherent cells that results due to the formation of biofilm are known to invade the slimy extracellular matrix that are made up of extracellular polymeric substances. These embedded cells serves the function of production of EPS component that is composed of genetic material, polysaccharides and lipids. These biofilms are capable of growth on the living as well as the non living things.
Formation of biofilm by the microbes occurs due to several factors namely nutritional factors, antibiotic attack and cellular recognition to the attachment site. The defined steps of the biofilm formation includes initial attachment, Irreversible attachment, Maturation I, Maturation II and Dispersion.
