Answer:
A)The limb bones are similar across these species because they share a common ancestor.
Explanation:
The forelimb of humans, horses, goats, and mice are homologous organs. Homologous organs are those which are similar in origin but dissimilar in function. These organs are made of the same bones humerus, ulna, and radius. The above for limb in the given animals perform different functions as they live in different habitats. The homologous structures indicates divergent evolution.
Answer with Explanation:
"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.
The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.
Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."
Sedimentary rocks form when sediments come together and forms the rocks, while metamorphic rock are those formed when sedimentary and igneous rocks compress under great heat and pressure.
