Homo erectus is believed to be the first confirmed species found outside Africa.

Explanation:

The human race is believed to have evolved in Africa because the evidences of evolution of major human species are found in Africa. The fossil evidences of Homo erectus were found in Georgia, China etc before millions of years. Evidences of all the human species that lived on earth before Homo erectus were found in the continent of Africa.

All the human species that lived before Homo erectus didn’t stand upright and move in two legs. It was only from the period of Homo erectus that humans stood upright and moved in two legs.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
