Humans are different from each other in many ways, including in their sizes, shapes, skin color, facial features, and handedness
. However, all humans are classified as one species because it is possible for one person from one location on the Earth to reproduce with another person from a different location on the Earth. What other evidence can be used in support of the idea that humans are a single species and unique from other species? A. All humans have one vertical line of symmetry in their body plans. B. Humans from different locations speak different languages. C. Humans from different locations can donate blood and organs to one another. D. All humans possess body hair.
<em>The correct option is C) Humans from different locations can donate blood and organs to one another.</em>
Explanation:
Organisms belonging to the same species can interbreed and produce fertile offsprings. As humans all around the world can interbreed and produce fertile embryo hence all human beings belong to the same species. Also, the organs and blood of organisms from the same species can be transferred depending on the compatibility. It is less likely for the human body to reject a graft from other human being rather than another species. Although, xenotransplantation has been practiced in the laboratory by scientists but it has not produced any good results.
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles.
The core, or middle, of the Sun is the hottest part. Hot gasses bubble up from the core to the surface of the Sun. When the gasses burn, heat and light are produced.
