Diatomic molecules are molecules composed only of two atom s, of either the same or different chemical element s. The prefix di-means two in Greek. Common diatomic molecules are hydrogen (H 2), nitrogen (N 2), oxygen (O 2), and carbon monoxide (CO).he bond in a homonuclear diatomic molecule is non-polar and covalent. In most diatomic molecules, the elements are nonidentical. Prominent examples include carbon monoxide, nitric oxide, and hydrogen chloride, but other important examples include MgO and NaCl.
Africa, which developed the world's oldest human civilization, gave humanity the use of fire a million and half to two million years ago. It is the home of the first tools, astronomy, jewelry, fishing, mathematics, crops, art, use of pigments, cutting and other pointed instruments and animal domestication.In short Africa gave the world human civilization.illions of years ago human life started in Africa, Australopithecus aphaeresis and Australopithecus africanus and Australopithecus robustus were all key rungs in the development of humanity.
Best Answer: Human life began in Africa, e.g., Olduvai Gorge and Sterkfontaine contain some of the earliest human fossils. There was an initial radiation of the hominids out of Africa into and through the middle east and on to Asia.eport Abuse. Well, the oldest skulls are found in Africa and African people have the largest gene pool of any race. In fact, every race has some 'african' markers in their DNA...So YEAH, life probably did begin somewhere in that part of the world.
