How does anatomy provide evidence for evolution?

Answers

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures. These are structures that unrelated organisms share because they evolved to do the same job.

Which biome covers the largest part of earth's surface?grassland
polar
marine
tropical rain forest

Answers

The oceans cover the earth's surface by approximately three-fourth or seventy five percent. It is the oldest and the largest biome. Thus, the marine biome is the largest biome which covers the earth's surface. This biome also is the common link among the other biomes in Earth.

Final answer:

The marine biome covers the largest part of Earth's surface, constituting about 71% of it. This biome is characterized by its saline water environment, diverse marine life, and significant role in maintaining the balance of Earth's ecosystem.

Explanation:

The biome that covers the largest part of Earth's surface is the marine biome, and it outflanks other biomes by a significant margin. Biomes are large biological environments characterized by certain types of flora and fauna, weather patterns, and other ecological traits. In our case, the various types of marine biomes altogether constitute approximately 71% of the Earth's surface, significantly outpacing the other biomes.

Characterized by its saline water-related features, this biome includes oceans, seas, reefs, and other bodies of saltwater. Marine life is incredibly diverse, encompassing extensive ranges of animal, plant, and microbial life forms. Unlike terrestrial biomes, such as the grassland, polar, and tropical rainforest, whose habitats are dominated by land-based life, the marine biome is characterized mainly by aquatic life.

It's important to note the significant role that the marine biome plays in the Earth's ecosystem. Its vast bodies of water regulate global weather patterns and provide a home for a massive quantity of the Earth's biodiversity.
