Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mt DNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Answer:
The majority of marine organisms are found in coastal regions.
Explanation:
The majority of marine organisms are found in coastal regions because ocean flows bring nutrient-rich water into coastal areas. Marine coasts are the type of environments that change through the weathering process and change in sea levels. Coastlines mostly consist of continental shelves that contain relatively shallow waters of having 200-meter depths only.
Since water is shallow here, photosynthetic processes are possible for marine life, which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the marine organisms so that they can use it. Aside from these reasons, cyclic upwellings in the sea also provide fresh and nutrient-rich waters for several species.
