<span>Breakwaters, seawalls, and groins are all examples of shoreline structures.
</span>
Shoreline structures are built with the purpose to change ocean waves, sand movements and currents. Breakwaters are built to minimise the intensity of wave action reducing erosion in the coast or and creating a safe harbourage for ports. A seawall is a defence wall constructed to protect human habitation, or other areas of human interest, from the action of tides or waves maintaining the coastal area where the wall is unchanged. <span>A </span>groin structure<span> built from an ocean shore perpendicular to the shoreline</span><span> that stops the water flow and limits </span>sediment's movement<span>. It is constructed to prevent great movement of sediments and erosion.</span>
The answer is C I believe
Genetic diversity
Explanation:
Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population.
- Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring.
- Mutation is the process of altering genetic sequences in population to production new breeds called mutants.
- Crossing-over is the exchange of chromosomes between two homologous pairs.
All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.

<span>Polypeptide
</span><span>
When Polypeptides join together, they form protein. The term Polypeptide chain is used to define the combination of Polypeptides. They are joined together by the peptide bonds. These Polypeptides are chains of amino acids. When one or more Polypeptide chains joined together, that is the time when Protein was born. As we all know, protein is very essential to our body. Because protein helps our body to function well. Protein makes our cells function properly. Can you imagine our body without protein? Thanks to Polypeptides chains that are joined together to form Protein so our body can function well. </span>
