Explanation:
Australopithecus (first ape-man): Australopithecus is considered as the connecting link between apes and man as they shared the characteristics of both. The fossil records shows that they appeared around 5 million years ago. <em>Australopithecus africanus</em> was about 1.5 meters high and had human as well as ape like features. It was with bipedal locomotion, omnivorous in their diet and had erect posture. It had human like teeth with small canines and large chewing teeth. The brain was more like an ape with the brain capacity of about 500 cc similar to that of an ape. He lived in caves, had projected brow ridges with no chin. Its believed that <em>Australopithecus africanus</em> gave rise to <em>Homo habilis</em> about 2 million years ago.
The earliest species of Homo genus is <em>Homo habilis</em>. They were skill full man also called as handy man or the tool maker. He had erect posture with bipedal locomotion. The teeth were like modern man. He was skilled and made tools with stones. Slowly with evolution the prognathous face changed to orthognathous in cro magnon (<em>Homo sapiens fossilis</em>).

Answer:
<em>The correct option is D. It is carbon dioxide released by respiration.</em>
Explanation:
The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.
Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.
