Answer: 4
Explanation:
A monomer is a small molecular mass molecule that is attached to other monomers, sometimes hundreds or thousands, by chemical bonds, usually covalent, forming macromolecules called polymers. Polymerization is the process of covalent bonding of the smallest monomers to the polymer. During polymerization, chemical groups are lost from the monomers so that they can bond. Examples are:
- Amino acids are the monomers of proteins.
- Nucleotides are the monomers of nucleic acids.
- Monosaccharides are the monomers of polysaccharides.
- Lipid monomers are the monomers of fatty acids
In this case, if we have the A and B monomers, the combinations can be A attached to A, A attached to B, B attached to B and B attached to A. This gives us a total of 4 different polymers.
The option which best explains how water conservation can reduce waterborne diseases in a community is 1. more people will have clean water to drink and bathe in.
If you have clean water, it is less likely you will contract a virus or some kind of a disease from water. So, there is no need to import water if you can just clean the one you have.
Full moon. a full moon happen quite often.
That would be a covalent bond. Hope this helps!
