Humans are different from each other in many ways, including in their sizes, shapes, skin color, facial features, and handedness
strojnjashka [21]

Answer:

<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.
