<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
Answer:
The diagram represents the Law of Dominance
Explanation:
Any particular trait can be dominant or recessive in an individual who is heterozygous for it depending on their inheritance pattern from the parent genotype. Although the individual will be carrying the recessive allele in their genetic code too, it is only the dominant phenotype that is expressed. The dominant trait is represented by the capital letter whereas the recessive trait is represented by a small case letter.

Answer:
Here are some. I discovered that the clean and unclean food and hygiene laws found in the Book of Leviticus have been based all this time on the God of Abraham's working knowledge of the germ theory of disease and the modern human body and other advanced fields of science unknown to mankind at that time and some fields of science still unknown to mankind today. These laws and instructions still apply to modern times for all humans to follow to help keep our bodies healthy and disease free until we grow old and die of old age.

answer:Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems (1). Key terms in this definition reflect some of the important principles of epidemiology.
