scientists draw about their experiment. Conclusions must be based on evidence-(observations and data that make you believe something is true). Scientist use their observations to draw a conclusion. They summarize what they have learned by analyzing their observations.
Mitosis is responsible for growth, repair and maintenance of an organism because it produces all the daughter cells that are genetically identical to one other and therefore creates new available cells that are specific to each tissue for growth and repair.

"The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 billion years ago. These fossils are of structures known as stromatolites, which are, in many cases, formed by the growth of layer upon layer of single-celled microbes, such as cyanobacteria. (Stromatolites are also made by present-day microbes, not just prehistoric ones.)
The earliest fossils of microbes themselves, rather than just their by-products, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago
Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago. However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible)."
