Answer 1

You are studying a new variant of a eukaryotic cell. The variant cell has mutated so that it no longer attaches well to surfaces or initiates the formation of a biofilm. The mutation in this cell has most likely affected the _____.

Mitochondria

Flagellum

Cell membrane

Glycocalyx

Answer:

Glycocalyx

Explanation:

Biofilms refer to the irregular layers of cells. These are formed when a group of cells arranges themselves at a solid or liquid surface.  The glycocalyx forms a layer around some animal cells. It has glycolipids and glycoproteins.   These substances allow the cells to recognize one another and to make contact with one another. The formation of adhesive communications that hold the cells in the biofilms is mediated by the components of the glycocalyx. Therefore, any mutation in the genes coding for components of glycocalyx would affect the ability of the cells to form biofilms.
