Answer:
end of cytokinesis
Explanation:
Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.
A) a large group of cells that grew without regulation.
A tumor is where there is a mutation that causes cells to lose their ability to self regulate, so they reproduce too fast and become unspecialised, causing a tumour.
Let me know if you have any questions
The answer is A because in the process of mitosis and meiosis chromosomes are single-stranded groups that are condensed to chromatin when the process of division of cells chromosomes replicate to make sure that the new daughter cells received the correct number of chromosomes
