natural selection

Explanation:

Competition leads to natural selection. Organisms always compete for scarce resources which enable them to survive in their environment. Some organisms inherited traits that give them an advantage over others in the competition for scarce resources in their environment.

These organism having such genetic or otherwise advantage are better able to survive in their environment compared to other members of their species lacking this advantage. This survival of the fittest is known as natural selection. It is a natural consequence of competition for scarce resources within the environment.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
