Carbohydrates and proteins are built up from their basic building blocks by the a. removal of a nitrogen atom between each two units b. addition of a water molecule between each two units c. removal of a water molecule between each two units d. addition of a carbon atom between each two units

Carbohydrates and proteins are built up from their basic building blocks by the removal of a water molecule between each two units.

Polymerization is defined as the process by which small molecules (monomers) aggregate to form larger molecules called polymers.

Polymerization may occur in two ways;

Carbohydrates and proteins are built up from their basic building blocks by the removal of a water molecule between each two units. The building blocks of proteins are amino acids while the building blocks of carbohydrates are monosaccharides.

it should be all of them because it asks if you included all of those in your answer

explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
