Explanation:

Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.

What are abiotic factors?

Abiotic factors are nonliving components of an ecosystem, such as temperature, light, wind, and moisture. They are the physical and chemical elements of an environment that influence the structure and function of ecosystems. Abiotic factors shape the biotic, or living, components of an ecosystem, which include plants, animals, and microorganisms. Abiotic factors determine what species of life can live in a particular ecosystem. For example, a cold, wet climate will support different species of plants and animals than a hot, dry climate. Abiotic factors also determine the carrying capacity, or the number of organisms that can be supported, of a given environment. Abiotic factors are essential to the functioning of all ecosystems and are constantly changing due to natural processes and human activities.
