Answer:
<h2>
Operons
</h2>
Explanation:
1. Operon: is a set of genes which are transcribed under the control of an operator gene. These genes are transcribed according to the requirement in the cell under a regulatory mechanism.
2. Or, an operon is a segment of DNA containing adjacent genes including i) structural genes, ii) an operator gene, and iii) a regulatory gene, which are transcribed together.
3. Thus an operon is a functional unit of transcription and genetic regulation which is regulated in a strict manner.
4. Example of operon; i) Lac operon in E.coli.

The DNA or deoxyribonucleic acid is the carrier of genetic information from all forms of living organisms. This is the main reason of the inheritance of traits, behaviors, attitude, physical appearances, and many more that helped, not just the human being, but all living organisms in the planet to adapt, adjust, evolve, and survive for generations and generations. The DNA is carried by the cells of the living organisms' body and is stored and shared eventually. Though it was discovered that the DNA is a long complicated helix that contains mostly all the information of life, this is stored in the nucleus of a cell because it is folded and condensed together with the other genetic materials.
Ocean acidification causes a decrease in the pH concentration of the oceans, mostly arises as a result of the entry of carbon dioxide from the atmosphere.
A fisherman noticing a shellfish's shell being very small and lack the thick hard shell may be due to Ocean acidification (option A).
- Ocean acidification is mainly caused by fossil fuels and leads to a decrease in the water's pH.
- It also causes a reduction in the amount of carbonate, a building block of shells and skeletons in seawater.
- This makes it very difficult for marine organisms, such as shell fish and corals, to form their shells and skeletons, and those with existing shells may begin to dissolve.
