In drastic reduction, what is being described above is the process called the founder effect. The founder effect is also the other term called in which it applies the definition above. This is made when a population has been created with the means of having small numbers and not too many individuals.
Cancer cells are the cells that divide rapidly than any other cells in the body. The drugs used in chemotherapy work on rapidly dividing cancer cells. Some cells of our body apart from cancer cells also divide rapidly along with the cancer cells such as the cells that line the stomach and the digestive tract. Chemotherapy drugs cannot differentiate the cancer cells and the normal cells so these drugs also attack the normal cells which divide rapidly along with the cancer cells. The drugs also attack the cells that are present in the roots of the hair. So, this results in the hair loss. Hair loss does not occur immediately after the chemotherapy treatment instead it starts after few treatments. The degree of the hair loss after chemotherapy depends on the drug type and process. So when the chemotherapy drugs are used it results in the hair loss and nausea.
Therefore, when chemotherapy drugs attack normal cells including the roots of the hair instead of cancer cells that divide rapidly along with the cancer cells it results in the hair loss and nausea.
Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
<span>By rebonding with another phosphate molecule through oxidative phosphorylation, it becomes recharged and the ADP to ATP process can be restarted. This allows for more cellular energy to be produced, and more metabolic actions to be undertaken. This is the major aspect of cell respiration.</span>
