Identification of the study groups, involved variables -independent, dependent, and control-.

Methodology description. Steps needed to get data.

Results. It includes data statistical analysis. This step involves testing the observations.

Discussion and Conclusion, through which the hypothesis might be rejected or accepted.

                        Factors that govern the ultimate size of hailstones are hail has strong storm clouds, especially strong heat, high liquid water content, large vertical range, large water droplets, and many cloud layers are formed by clouds below 0 ° C (32 ° F). This type of intense heat may also indicate the presence of a tornado.

Your body constantly produces new cells. Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells. So, as a tumour gets bigger, cancer cells can spread to surrounding tissues and structures by pushing on normal tissue beside the tumour. Cancer cells also make enzymes that break down normal cells and tissues as they grow. Cancer that grows into nearby tissue is called local invasion or invasive cancer.
