Question

7. The diagram below represents cellular growth that can occur in human skin after long exposure to ultraviolet light.Which statement provides the best explanation for this growth pattern?A. Uncontrolled mitotic division occurred as a result of gene mutations.B. Manipulation of genes caused the movement of embryonic skin cells.C. An immune reaction triggered the formation of excess blood cells.D. Exposure to light stimulated the development of cells containing ozone.

Answer 1

This abnormal growth of the skin's cells can be attributed to the ultraviolet light that can cause mutations in the genes that control their mitotic processes. We can see how this is stated in the first answer option: "A. uncontrolled mitotic division occurred as a result of gene mutations".
