Answer:
B: Freshwater biomes are a vital source of drinking water.
Explanation:
It's not A because oceans are part of marine biomes, and oceans contain 97% of the Earth's water and covers 71% of the Earth's surface.
It's not C because marine biomes supplies more oxygen than freshwater biomes. Marine algae supply much of the world's oxygen supply, and they take in a huge amount of atmospheric carbon dioxide.
It's not D because freshwater biomes include streams, rivers, ponds, and lakes. Aquatic biomes include oceans, coral reefs, and estuaries.
It's B because freshwater biomes are very important to our survival because they supply people with more than half of their drinking water.
Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.
