these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.  

prophase is the first step in mitosis and will show one huge circle (nucleus) and centrioles - nothing is being done to it. metaphase is the third step and where the chromatids meet in the middle and the centrioles are at opposite ends. anaphase is the fourth step and where the chromatids start to split/separate. telophase is the second to last step where the chromatids start to split along with the centrioles, it looks like there is getting ready to be two different cells. if you follow this, then it should you to answer what it looks like. have a great day and i hope i you! if i did not answer your question or you are confused, let me know and i will you as much as i can.
