Explanation / Answer

Ans.1 (B)

there are 10 times more bacterial cells in your body than human cells

Ans.2 (E)

All the choices are correct as microorganisms are involved in all of these. They are used in cleaning pollutants, they cause diseases , they are used in various medications for curing diseases and they are used in baking industry for preparing food.

Ans.3 (C)

Bacteria provide protection to our body by protecting us from disease causing bacteria.

Ans.4 (E)

All the choices are correct as archea are found in rods, spheres and spirals form, they contain rigid cell walls, they are found as single cells and they reproduce by binary fission.
