Explain the process of mitosis in a tissue culture for cancer cells

Answer and explanation;

-Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

-In tissue culture, cancer cells are taken from a living organism and grown in a culture. Cancer cells grow at an uncontrolled rate. Cancer cells do not stop growing when they are touching; they continue growing. Cancer cells grow multiple layers thick. Cancer cell growth differs from normal cell growth and the number of mitotic divisions are unlimited.

-Producing three or more daughter cells instead of normal two is a mitotic error called tripolar mitosis or multipolar mitosis (direct cell triplication / multiplication). Other errors during mitosis can induce apoptosis (programmed cell death) or cause mutations. Certain types of cancer can arise from such mutations.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
