A hexahedron (plural: hexahedra) is any polyhedron with six faces. A cube, for example, is a regular hexahedron with all its faces square, and three squares around each vertex. There are seven topologically distinct convex hexahedra, one of which exists in two mirror image forms.
Some bacteria that can help the environment are called decomposers. They are nature's recyclers! They return basic chemicals to the environment for living things to reuse! For example, the leaves of many trees die in the Autumn and drop to the ground.ome bacteria that can help the environment are called decomposers. They are nature's recyclers!

Bacterial Cell Function. In the grand scheme of things, the function of each bacterial cell begins and ends with collecting enough nutrients to survive. Bacterial cells consist of a phospholipid bilayer, and in some cases a layer of peptidoglycan.n the grand scheme of things, the function of each bacterial cell begins and ends with collecting enough nutrients to survive.
