Ow many molecules of water are released during the polymerization of a 20 monomer-long cellulose molecule?

The correct answer will be- 19 H₂O molecules.

Explanation:

The formation or synthesis of large macromolecules from monomers is a dehydration reaction. During synthesis one -OH from one monomer while one-H from another monomer is released during bond formation. These two ions bind together and form H₂O molecules.

So a bond formation between two monomers releases one H₂O molecule. If the chain has 20 monomers it will have 19 bonds and thus 19 molecules of H₂O will be released.

Thus, 19 H₂O molecules are the correct answer.

d. groundwater flows through the subsoil and deposits minerals.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
