Whales use their lower jawbone to the middle ear. whereby they can ear clearly while they are in the water. Human ears and dolphins ears they work the same . They receive sound directly from the air.
In similar way dolphins and human ears are placed in basic anatomical location which is same as on the head. Without a medium hearing is not possible.
The medium sound for human is air. Sound travels 343 meters per second in air and 147 meters per second in water. The most effective way of transmitting sound waves is through water.
We can say that the sound will be fast to travel in medium if the molecules are closer.
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.
