(A)The first organisms to travel from Earth to space were not human beings but fruit flies. In 1947, the United States military launched a rocket into space containing the fruit flies to test the effects of radiation at high altitudes. The rocket traveled 109 kilometers and opened its parachute. Scientists recovered the fruit flies, which were still alive after their space journey.
